Baby food pouches and Baby-Led Weaning: Associations with energy intake, eating behaviour and infant weight status.

Although concern is frequently expressed regarding the potential impact of baby food pouch use and Baby-Led Weaning (BLW) on infant health, research is scarce. Data on pouch use, BLW, energy intake, eating behaviour and body mass index (BMI) were obtained for 625 infants aged 7-10 months in the First Foods New Zealand study. Frequent pouch use was defined as ≥5 times/week during the past month. Traditional spoon-feeding (TSF), "partial" BLW and "full" BLW referred to the relative proportions of spoon-feeding versus infant self-feeding, assessed at 6 months (retrospectively) and current age. Daily energy intake was determined using two 24-h dietary recalls, and caregivers reported on a variety of eating behaviours. Researchers measured infant length and weight, and BMI z-scores were calculated (World Health Organization Child Growth Standards). In total, 28% of infants consumed food from pouches frequently. Frequent pouch use was not significantly related to BMI z-score (mean difference, 0.09; 95% CI -0.09, 0.27) or energy intake (92 kJ/day; -19, 202), but was associated with greater food responsiveness (standardised mean difference, 0.3; 95% CI 0.1, 0.4), food fussiness (0.3; 0.1, 0.4) and selective/restrictive eating (0.3; 0.2, 0.5). Compared to TSF, full BLW was associated with greater daily energy intake (BLW at 6 months: mean difference 150 kJ/day; 95% CI 4, 297; BLW at current age: 180 kJ/day; 62, 299) and with a range of eating behaviours, including greater satiety responsiveness, but not BMI z-score (6 months: 0.06 (-0.18, 0.30); current age: 0.06 (-0.13, 0.26)). In conclusion, neither feeding approach was associated with weight in infants, despite BLW being associated with greater energy intake compared with TSF. However, infants who consumed pouches frequently displayed higher food fussiness and more selective eating.

Development and validation of the baby eating behaviour coding system (BEBECS) to assess eating behaviour during complementary feeding.

Eating behaviour in children is a matter of study for which diverse tools have been designed. Coding systems for videotaped meals allow the extraction of detailed in vivo information; however, there is no tool available for infants following a Baby-Led Weaning (BLW) method. This study aimed to create and validate a new tool to assess eating behaviour in infants during weaning, applicable regardless of the complementary feeding method. The Baby Eating Behaviour Coding System (BEBECS) was developed comprising time variables, behaviours, feeder-led actions, and other meal-related variables. Sixty videos of infants aged 6-18 months following spoon-feeding (SF) or BLW methods were coded by two trained coders. These scores were analysed together with intake and maternal ratings of liking and calmness. Additionally, combined analysis and internal comparison assessed the possible differences in BEBECS variables between SF and BLW. Inter-rater and test-retest reliability had good to excellent agreement: Cohen's Kappa >0.75, Lin's CCC >0.70, and Intraclass Correlation Coefficient >0.75, for almost all variables. Infants' liking and intake of the offered food correlated positively with meal duration and total count of mouth approaches but negatively with having leftovers and time between mouth approaches. Infants' calmness and tiredness were negatively correlated. More food than initially offered was available during the meal in BLW but not in SF. There was a tendency towards more autonomous behaviour in BLW infants regarding changes observed in the time the food was in the mouth at each stage (6, 12, and 18 months). In conclusion, BEBECS has the potential to be a valid tool for application in the research of infant eating behaviour during weaning by trained coders.

Household food insecurity and novel complementary feeding methods in New Zealand families.

Optimal nutrition during infancy is critical given its influence on lifelong health and wellbeing. Two novel methods of infant complementary feeding, commercial baby food pouch use and baby-led weaning (BLW), are becoming increasingly popular worldwide. Household food insecurity may influence complementary feeding practices adopted by families, but no studies have investigated the use of BLW and baby food pouches in families experiencing food insecurity. The First Foods New Zealand study was a multicentre, observational study in infants 7.0-9.9 months of age. Households (n = 604) were classified into one of three categories of food insecurity (severely food insecure, moderately food insecure, and food secure). The use of complementary feeding practices was assessed via a self-administered questionnaire, both at the current age (mean 8.4 months) and retrospectively at 6 months. Mothers experiencing severe food insecurity had 5.70 times the odds of currently using commercial baby food pouches frequently (≥5 times/week) compared to food secure mothers (95% CI [1.54, 21.01]), reporting that pouches were 'easy to use' (89%) and made it 'easy to get fruits and vegetables in' (64%). In contrast, no evidence of a difference in the prevalence of current BLW was observed among mothers experiencing moderate food insecurity (adjusted OR; 1.28, 95% CI [0.73, 2.24]) or severe food insecurity (adjusted OR; 1.03, 95% CI [0.44, 2.43]) compared to food secure mothers. The high prevalence of frequent commercial baby food pouch use in food insecure households underscores the need for research to determine whether frequent pouch use impacts infant health.

Complementary feeding approach and maternal responsiveness in 8- and 12-month-old Italian infants: A longitudinal study.

In Western countries, infants are usually introduced to solids through spoon-fed puréed foods (parent-led weaning, PLW). However, an alternative approach known as "baby-led weaning" (BLW), in which infants usually participate in family meals and eat independently, is becoming increasingly popular. We investigated the relationship between the type of complementary feeding approach and maternal responsiveness to infant feeding cues in a longitudinal sample of 178 infants observed at 8 and 12 months. Mothers reported the complementary feeding method used and, from video-recorded meals, we coded the proportion of time infants self-fed and rated maternal responsiveness by means of the Responsiveness to Child Feeding Cues Scale (Hodges et al., 2013). Responsiveness to infant receptiveness and fullness cues were significantly correlated at 8 months, but not at 12 months, when unresponsiveness decreased for receptiveness but remained stable for fullness cues. Thus, as infants got older, mothers were increasingly tuned in to their receptiveness cues. However, we did not observe the same pattern for fullness cues, perhaps because mothers were concerned that their infants did not eat enough. Moreover, at both time points, mothers were more responsive to infants' receptiveness than fullness cues, possibly due to an evolutionary drive to protect infants from starvation. Finally, responsiveness to fullness, but not responsiveness to receptiveness, was positively related to the proportion of infant self-feeding, but there were no significant differences in responsiveness depending on the self-reported complementary feeding approach. Thus, a weaning style that emphasizes independent feeding, regardless of whether this is labeled as BLW, may promote more infant-centered maternal responses at the end of the meal, with potential implications for promoting infant self-regulation not only at mealtimes, but also in other domains.

To feed or let eat! A scale of independence, exploration, and family to measure baby-led weaning as a complementary feeding approach.

BACKGROUND: This article reports the development and validation of a measure of parents' use of baby-led weaning (BLW). BLW is a child-centred approach to complementary feeding where the infant is allowed to eat whole foods (rather than purees) and explore a variety of foods and textures. To date, parents' use of BLW has been assessed using either single items or a wide variety of measures. METHOD: In this study, exploratory and confirmatory factor analyses on independent samples supported three BLW subscales: independence, exploration, and family. RESULTS: The final 13-item scale showed adequate fit statistics and good reliability (χ2 (62) = 115.02, p < 0.001; CFI = 0.98; TLI = 0.98; RMSEA = 0.05; SRMR = 0.06; exploration a = 0.738; family a = 0.715; independence a = 0.809). In addition, the scale demonstrated good external validity and related in theoretically expected ways to an infant feeding-style measure and parent report of complementary feeding approach. This study was limited as it was mostly white parents, and the scale should be validated on a more diverse sample. CONCLUSIONS: Future research can use this scale to examine if BLW relates to infant taste preferences, parenting styles, and child eating behaviours to improve child nutrition and health outcomes.

Baby-led weaning: A thematic analysis of comments made by parents using online parenting forums.

BACKGROUND: Baby-led weaning (BLW) centres on making the baby an active partner, rather than a passive recipient of complementary feeding. Key features of BLW include self-feeding foods in their natural form, eating with the rest of the family and consuming family foods. This differs from traditional weaning (TW) where parents initially spoon feed purees, alongside finger foods, before graduating to more textured food. Previous research, however, has suggested parents may not fully adhere to one weaning style. The present study aimed to explore how the meaning and interpretation of BLW may contribute to the weaning style used. METHODS: Messages and responses posted on three UK parenting forums, and relating to complementary feeding, were analysed using an interpretive thematic approach. RESULTS: The characterisation of BLW by parents was varied, although they described BLW having an ethos which included trusting the baby, role modelling, developing confidence with food and sharing the social aspects of mealtimes. BLW also offered an alternative to those actively seeking something different or a default for those whose baby refused purees or spoon feeding. BLW felt like a natural progression, with low parental effort for some, and a source of anxiety, stress, choking risk and mess for others. Many parents struggled to find a process (what to eat and when) within BLW that they could follow. Finger foods were used synonymously with BLW, but many mixed/blurred aspects of both TW and BLW. CONCLUSIONS: The interpretation of BLW varies considerably between parents and a broader definition of BLW may be required, along with guidance on the process and purpose of BLW.

Infant egg consumption during introduction to solid food remains low in the United Kingdom but increases with infant age and a baby-led weaning approach.

BACKGROUND: As a nutritious food-providing protein, essential fatty acids, vitamin D, iodine and choline eggs have historically been central to an infant weaning diet. However, food poisoning scares and allergy concerns have contributed to low consumption among infants aged 6-12 months. METHODS: This paper presents a secondary data analysis of infant egg exposure and intake using three weaning data sets: a 7-day food frequency questionnaire (n = 297), a 24-h recall (n = 180) and a 3-day weighed food diary (n = 71). Egg introduction, frequency of consumption and intake in grams were analysed for infants aged 6-8, 9-10 and 11-12 months). Comparisons were made by whether infants were following a baby-led approach to weaning (where infants self-feed family foods) or a traditional approach where pureed foods are given alongside finger foods. Data were collected in the United Kingdom between 2015 and 2018. RESULTS: Our data showed that despite introduction being recommended from the start of weaning at 6 months of age by the Department of Health, just 54% of infants aged 6-8 months had ever been offered eggs. Average egg intake was one to two times per week, increasing with age. However, in terms of frequency and grams consumed, our data suggest a small increase in consumption compared with previous research, although limitations of our smaller sample size should be noted. Finally, a baby-led approach was associated with increased exposure and consumption; baby-led infants consumed eggs twice as frequently as spoon-fed infants. CONCLUSIONS: The findings have important implications for public health messaging and for supporting families in introducing solid foods.

Relationship of baby led weaning to other parenting and feeding constructs.

BACKGROUND: Baby-led weaning (BLW), a popular complementary feeding style, prioritizes exploration of foods, independence of children in eating, and eating with family. Though BLW has received popular attention, empirical evidence is limited. This study measured parents' reports of BLW, parenting style, and feeding practices; analyzed BLW's relation to children's dietary intake; examined how demographic variables such as age, parent sex, education, and marital status related to the prevalence of using BLW. METHODS: This cross sectional study recruited 313 parents with children ages 6-30 months via Cloud Research, an online survey platform where individuals complete surveys for compensation. Hierarchical regressions examined how feeding style, dietary intake, and parenting style related to independence, exploration, and family subscales of BLW after controlling for relevant demographics. FINDINGS: The majority (69.3%) of participants identified as female, white (76.6%), middle-class (52.4%), married (69%), and a third had a bachelor's degree (37.4%). Restrictive feeding practices, Ellyn Satter's division of responsibility, and the parents' sex were significant predictors of all subscales of BLW. DISCUSSION: Parents who use BLW allowed for an autonomous food experience and were less likely to restrict or control the child's eating. BLW appears to be related to, but distinct from, well-researched parent feeding practices such as restriction and division of responsibility. APPLICATION TO PRACTICE: These findings might be useful in education and interventions for healthcare professionals. Future research on BLW should examine how child behavior and nutrition outcomes compare to other feeding practices.

The effect of baby-led weaning and traditional complementary feeding trainings on baby development.

PURPOSE: The aim of this study was to evaluate the risks of self-feeding, transition to early solid food and family meals, choking risk, anemia risk and obesity risk in 6-12-month-old infants who were introduced to complementary feeding using the traditional complementary feeding (TCF) and baby-led weaning (BLW) methods/training. DESIGN AND METHODS: Mothers of infants who had not yet transitioned to complementary feeding were included in this randomized study. The mothers of 62 infants included in the study were randomized into the intervention groups as TCF and BLW, classified according to the number of children and education level. The research was carried out according to the CONSORT-2010 guidelines after randomization and was concluded with 52 infants and their mothers. RESULTS: It was found in the study that self-feeding and transition to solid foods in infants fed with the BLW method was higher than the infants fed with the TCF method (p < 0.05). A significant increase was observed in the hemoglobin level of infants fed with the BLW method over time (p < 0.001). CONCLUSIONS: It was concluded that the BLW method did not lead to risks of obesity, anemia and iron deficiency in transition to complementary feeding. Secondary results indicated that feeding with the BLW method promoted self-feeding and early transition to solid foods and did not lead to the risk of choking. PRACTICE IMPLICATIONS: Complementary feeding with the BLW method can be safely used by both mothers, healthcare professionals and researchers. TRIAL REGISTRATION: register.

The weaning practices: A new challenge for pediatricians?

Introduction of complementary feeding, or weaning, is the period where infants are gradually introduced to solid foods, with a progressive reduction of breastfeeding or bottle-feeding. Weaning represents a crucial nutritional moment in the growth and development of infants, and it can also affect future health. Throughout the years, various weaning strategies have been proposed, ranging from classic to baby-led weaning. Recently, vegetarian-/vegan-based approaches are also being increasingly adopted by young parents. This rostrum aims to critically address the safety profiles of current weaning practices for infants and to highlight the important role of pediatricians in choosing the most advisable weaning approach for their patients.

Comparison of food and nutrient intake in infants aged 6-12 months, following baby-led or traditional weaning: A cross-sectional study.

BACKGROUND: A baby-led approach to weaning (BLW) encompasses self-feeding and self-selecting graspable foods, offering an alternative to traditional weaning (TW). This cross-sectional study explored adherence to characteristics of BLW and differences in food group exposure and nutrient intake between babies following either TW or BLW. METHODS: Nutritional data were collected via multiple-pass 24-h recall, following parental completion of an online survey. RESULTS: Infants were grouped according to age (6-8 months; TW [n = 36] and BLW [n = 24]) and (9-12 months; TW [n = 24] and BLW [n = 12]). BLW babies were more likely to be breast fed (p = 0.002), consumed a higher percentage of foods also consumed by their mother (p = 0.008) and were fed less purees (p < 0.001) at 6-8 months. TW babies were spoon fed more (p ≤ 0.001) at all ages. Amongst babies aged 6-8 months, total intake (from complementary food plus milk) of iron (p = 0.021), zinc (p = 0.048), iodine (p = 0.031), vitamin B12 (p = 0.002) and vitamin D (p = 0.042) and both vitamin B12 (p = 0.027) and vitamin D (p = 0.035) from complementary food alone was higher in babies following TW. Compared to TW, BLW babies aged 6-8 months had a higher percentage energy intake from fat (p = 0.043) and saturated fat (p = 0.026) from their milk. No differences in nutrient intake were observed amongst infants aged 9-12 months. Few differences were observed between groups in their number of exposures to specific food groups. CONCLUSIONS: TW infants had higher intakes of key micronutrients at 6-8 months, although there were few differences in nutritional intake at 9-12 months or food group exposure between babies following TW or BLW. BLW appears to be socially desirable. Guidance for parents is required, along with larger, longer-term studies, which explore the potential impact of BLW in later childhood.

Estimated energy and nutrient intake for infants following baby-led and traditional weaning approaches.

BACKGROUND: Baby-led weaning (BLW), where infants self-feed without the use of spoon-feeding by a caregiver, continues to be a popular approach for starting solids. However, concerns remain amongst health professionals that infants using this method may not consume sufficient energy or nutrients from solid foods. Little research has examined how different weaning approaches shape dietary intake. The present study aimed to use a 3-day weighed diet diary to measure estimated energy and nutrient intake in infants aged 6-12 months. METHODS: Diet diaries were completed by 71 parents and analysed to compare estimated infant intake from milk and solid foods for those either following a BLW or traditional spoon-feeding approach (TW). Intake was analysed for each weaning group in two age groups: 26-39 and 40-52 weeks, to account for different eating patterns at the start and end of the weaning process. RESULTS: For the younger infants, significant differences in estimated energy intake were found, with TW infants consuming 285 kcal from solid foods compared with 120 kcal for BLW infants. Conversely, BLW infants consumed more calories and nutrients from breast or formula milk, consistent with a slower transition to solid foods. No differences were found in estimated intake amongst older infants, suggesting that BLW infants had 'caught up' with their spoon-fed peers. CONCLUSIONS: Overall, few infants regardless of weaning group met recommended intake guidelines for energy (either over or under consuming) with many deficient in iron and zinc intake. The findings are important for those supporting parents through the transition to solid foods.

A quasi-experimental intervention protocol to characterize the factors that influence the acceptance of new foods by infants: mothers' diet and weaning method. Dastatuz project.

BACKGROUND: Children usually refuse to eat and taste fruits and vegetables; and turning unhealthy eating habits around is an important social challenge in industrialized countries. The Dastatuz project aims to study children food neophobia and to enhance fruit and vegetable acceptance. METHODS: A quasi-experimental, multicentre, controlled and prospective intervention study is proposed, in which early factors influencing new food acceptance will be studied. Mothers in the third trimester of pregnancy (n = 144) and their infants will be the study population. Experimental groups will be established based on mothers´ fruit and vegetable intake (standard or high intake) and weaning method (baby lead weaning vs spoon feeding). The project will assess the possible impact of maternal diet and complementary feeding on infants eating behaviour until 18 months of age. Outcome measures will comprise maternal diet and psychological features during pregnancy and breast-feeding (validated questionnaires). Compositional and physicochemical analysis of milk during breastfeeding will also be carried out. During weaning, until 18 months of age, children's diet will be assessed with 24 h recalls and acceptance of new fruits and vegetables will be studied using video recording. DISCUSSION: If the intervention is effective, this research work would have a high potential to be transferred to future public health programs or nutrition guidelines, as a feasible solution to achieve a higher intake of fruits and vegetables among children. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov. Identifier: NCT04262102 . Registration date: February 10, 2020 - Retrospectively registered.

Baby-led weaning in Italy and potential implications for infant development.

Baby-led weaning is an approach to complementary feeding that emphasizes an infant's ability to self-feed rather than being spoon fed, and to eat minimally-processed foods rather than puréed foods. This study aimed to investigate the variability in infant feeding practices and the possible association with developmental milestones in an Italian population. A sample of 1245 mothers of 6-12 month-old infants completed an online survey about complementary feeding and their infant's attainment of developmental milestones. Infants' eating of family food was positively related to self-feeding and to a lower consumption of puréed foods. As in previous studies in the UK and New Zealand, a baby-led weaning style was positively associated with breastfeeding, exposure to complementary foods around six months of age, earlier exposure to both finger and family foods, and higher interest in family food and shared family meals. Infants who were introduced to solid foods using a baby-led weaning approach were more likely to have met important developmental milestones; when controlling for covariates, percentage of family feeding was positively associated with sitting unsupported at an earlier age and a low spoon-feeding style was associated with crawling at an earlier age. These data suggest that baby-led weaning should be defined more comprehensively. Moreover, its potential influence on developmental domains beyond diet and eating behavior warrants future targeted exploration.

Baby-led weaning: prevalence and associated factors in Spain.

The main goals of this study are to estimate the percentage of mothers who declared feeding their children with baby-led weaning (BLW) and to characterize them. A cross-sectional survey was carried out in 2016 targeting women who had given birth in 2016 (sample size 6777) in Galicia (Spain). The questionnaire included questions regarding the mother's characteristics and behaviors, attitudes, and practices related to BLW. Prevalence of exclusive and non-exclusive BLW was estimated. Different maternal characteristics were evaluated for their possible association with BLW using a logistic regression model. The percentages and ORs were presented with a 95% confidence interval. The study included 6355 women, of which 38.6% (37.4-39.9) had heard of BLW and the overall prevalence of BLW was estimated at 14.0% (13.1-14.9). Prevalence of exclusive BLW was estimated at 2.1% (2.4-3.3). No differences were observed when age was taken into consideration. Children fed with BLW were more likely among mothers who continue with exclusive breastfeeding (OR, 4.1 (95% CI, 3.3-5.0)); live in an urban setting (OR, 1.6 (1.2-2.2)); or have a higher level of education (OR, 1.3 (1.1-1.5)).Conclusion: Full adherence to BLW seems low among mothers who claimed to have fed their children following this method.What is Known:• Baby-led weaning (BLW) has been present in our society for almost two decades, but it remains unclear how many mothers choose BLW for their children.What is New:• BLW is not a common choice for weaning in Spain, and more than half of the mothers had not heard about it.• Full adherence to BLW seems low among mothers who claimed to have fed their children following this method.

Spoonfeeding is associated with increased infant weight but only amongst formula-fed infants.

Infant feeding experiences are important for the development of healthy weight gain trajectories. Evidence surrounding milk feeding and timing of introduction to solids is extensive; however, the impact of the method of introducing solids on infant growth has been relatively underexplored. Baby-led weaning (where infants self-feed family foods) is proposed to improve appetite regulation, leading to healthier weight gain and a reduced risk of obesity. However, the evidence is mixed and has methodological inconsistencies. Furthermore, despite milk being a large part of the infant diet during the period infants are introduced to solid foods, its influence and interaction with introductory style have not been considered. The aim of this study was to explore growth among infants aged 3-12 months according to both style of introduction to solid foods and milk feeding; 269 infants were weighed and measured, and body mass index (BMI) computed. The results showed that overall, infants who were spoon-fed (compared with self-fed) at introduction to complementary feeding (CF) had greater length (but not weight or BMI). However, when milk feeding was accounted for, we found that infants who were both spoon-fed and fully formula fed had greater weight compared with spoon-fed, breastfed infants. There was no significant difference in weight among self-fed infants who were breastfed or formula fed. The results highlight the importance of considering infant feeding as a multicomponent experience in relation to growth, combining both milk feeding and method of CF. This relationship may be explained by differences in maternal feeding style or diet consumed.

Standard v. baby-led complementary feeding: a comparison of food and nutrient intakes in 6-12-month-old infants in the UK.

OBJECTIVE: To compare food and nutrient intakes of infants aged 6-12 months following a baby-led complementary feeding (BLCF) approach and a standard weaning (SW) approach. DESIGN: Participants completed an online questionnaire consisting of sociodemographic questions, a 28 d FFQ and a 24 h dietary recall. SETTING: UK. PARTICIPANTS: Infants (n 134) aged 6-12 months (n 88, BLCF; n 46, SW). RESULTS: There was no difference between weaning methods for the food groups 'fruits', 'vegetables', 'all fish', 'meat and fish', 'sugary' or 'starchy' foods. The SW group was offered 'fortified infant cereals' (P < 0·001), 'salty snacks' at 6-8 months (P = 0·03), 'dairy and dairy-based desserts' at 9-12 months (P = 0·04) and 'pre-prepared baby foods' at all ages (P < 0·001) more often than the BLCF group. The SW group was offered 'oily fish' at all ages (P < 0·001) and 6-8 months (P = 0·01) and 'processed meats' at all ages (P < 0·001), 6-8 months (P = 0·003) and 9-12 months (P < 0·001) less often than the BLCF group. The BLCF group had significantly greater intakes of Na (P = 0·028) and fat from food (P = 0·035), and significantly lower intakes of Fe from milk (P = 0·012) and free sugar in the 6-8 months subgroup (P = 0·03) v. the SW group. Fe intake was below the Reference Nutrient Intake (RNI) for both groups and Na was above the RNI in the BLCF group. CONCLUSION: Compared with the SW group, the BLCF group was offered foods higher in Na and lower in Fe; however, the foods offered contained less free sugar.

Differences in dietary composition between infants introduced to complementary foods using Baby-led weaning and traditional spoon feeding.

BACKGROUND: Baby-led weaning (BLW) is a method of introducing solid foods to infants, which centres around the infant self-feeding family foods. BLW has grown in popularity over the last 10 years; however, although research is starting to build around the safety and impact of the method, research examining intake is sparse. This is important because concerns have been raised by healthcare providers regarding the nutrient and energy sufficiency of BLW. The present study aimed to invstigate exposure to different food types based on different weaning approaches. METHODS: One hundred and eighty parents completed a 24-h recall of the foods given to their babies aged 6-12 months. Respondents were split into those following strict BLW, loose BLW and traditional spoon-feeding. Recalls were examined to ascertain the number of times in 24 h infants were given different types of foods, including iron-containing foods. The results were then compared between different weaning groups and age groups. RESULTS: Several significant differences were found between the frequency of foods eaten by different weaning and age groups: in the youngest age group, strict BLW infants were more likely to be exposed to vegetables (P = 0.000) and protein (P = 0.002) than traditionally weaned babies, whereas, at all age groups, the traditionally weaned group had the highest exposure to composite meals. However, no significant differences were found in reported exposure to iron-containing foods between weaning groups at any age. Maternal age, education and milk feeding method were controlled for throughout the analyses. CONCLUSIONS: The findings add to a growing body of evidence that suggest a BLW approach may be safe and sufficient.

Mediation Analysis as a Means of Identifying Dietary Components That Differentially Affect the Fecal Microbiota of Infants Weaned by Modified Baby-Led and Traditional Approaches.

The introduction of "solids" (i.e., complementary foods) to the milk-only diet in early infancy affects the development of the gut microbiota. The aim of this study was to determine whether a "baby-led" approach to complementary feeding that encourages the early introduction of an adult-type diet results in alterations of the gut microbiota composition compared to traditional spoon-feeding. The Baby-Led Introduction to SolidS (BLISS) study randomized 206 infants to BLISS (a modified version of baby-led weaning [BLW], the introduction of solids at 6 months of age, followed by self-feeding of family foods) or control (traditional spoon-feeding of purées) groups. Fecal microbiotas and 3-day weighed-diet records were analyzed for a subset of 74 infants at 7 and 12 months of age. The composition of the microbiota was determined by sequencing of 16S rRNA genes amplified by PCR from bulk DNA extracted from feces. Diet records were used to estimate food and dietary fiber intake. Alpha diversity (number of operational taxonomic units [OTUs]) was significantly lower in BLISS infants at 12 months of age (difference [95% confidence interval {CI}] of 31 OTUs [3.4 to 58.5]; P = 0.028), and while there were no significant differences between control and BLISS infants in relative abundances of Bifidobacteriaceae, Enterobacteriaceae, Veillonellaceae, Bacteroidaceae, Erysipelotrichaceae, Lachnospiraceae, or Ruminococcaceae at 7 or 12 months of age, OTUs representing the genus Roseburia were less prevalent in BLISS microbiotas at 12 months. Mediation models demonstrated that the intake of "fruit and vegetables" and "dietary fiber" explained 29% and 25%, respectively, of the relationship between group (BLISS versus control) and alpha diversity.IMPORTANCE The introduction of solid foods (complementary feeding or weaning) to infants leads to more-complex compositions of microbial communities (microbiota or microbiome) in the gut. In baby-led weaning (BLW), infants are given only finger foods that they can pick up and feed themselves-there is no parental spoon-feeding of puréed baby foods-and infants are encouraged to eat family meals. BLW is a new approach to infant feeding that is increasing in popularity in the United States, New Zealand, the United Kingdom, and Canada. We used mediation modeling, commonly used in health research but not in microbiota studies until now, to identify particular dietary components that affected the development of the infant gut microbiota.

Patterns and predictors of food texture introduction in French children aged 4-36 months.

The aims of this study were to describe which and when food textures are offered to children between 4 and 36 months in France and to identify the associated factors. An online cross-sectional survey was designed, including questions about 188 food texture combinations representing three texture levels: purées (T1), soft small pieces (T2) and hard/large pieces and double textures (T3). Mothers indicated which combinations they already offered to their child. A food texture exposure score (TextExp) was calculated for all of the texture levels combined and for each texture level separately. Associations between TextExp and maternal and child characteristics and feeding practices were explored by multiple linear regressions, per age class. Answers from 2999 mothers living in France, mostly educated and primiparous, were analysed. Over the first year, children were mainly exposed to purées. Soft and small pieces were slowly introduced between 6 and 22 months, whereas hard/large pieces were mainly introduced from 13 months onwards. TextExp was positively associated with children's number of teeth and ability to eat alone with their finger or a fork. For almost all age classes, TextExp was higher in children introduced to complementary feeding earlier, lower for children who were offered only commercial baby foods and higher for those who were offered only home-made/non-specific foods during the second year. Our study shows that until 12 months of age the majority of French children were exposed to pieces to a small extent. It provides new insights to further understand the development of texture acceptance during a key period for the development of eating habits.
