The Co-Parenting Across Family Structures Scale: Replication for Mandarin parents.

Co-parenting, the undertaking of parents working together to raise their children, is well documented as an important consideration of children's adjustment in Western countries, but we know less about the role of co-parenting in other cultures. In China, for example, co-parenting has only recently emerged in the social science literature. This study aimed to examine the cultural sensitivity of the CoPAFS instrument among Chinese Mandarin-speaking parents. CoPAFS is a 27-item survey designed to assess co-parenting across married and unmarried family structures originally developed in English. Data were collected from 729 Chinese-speaking and 348 English-speaking respondents. Factor analyses and confirmatory factor analyses indicated that the overall model fit for the translated co-parenting measure was acceptable in Mandarin. However, the five CoPAFS subscales (trust, respect, communication, acrimony, and value) differed across comparison groups, with communication notable for its lack of endorsement among Chinese couples. Implications of measuring co-parenting within Chinese families are offered.

Grappling with tradition: the experiences of cisgender, heterosexual mothers and fathers in elective co-parenting arrangements.

Elective co-parenting families, meaning two (or more parents) who are not in a romantic relationship having a child together, are becoming more common amongst cisgender, heterosexual parents. The study of elective co-parenting families offers researchers a unique opportunity to decouple co-parenting relationships from romantic relationships, but little research to date has explored their experiences. This study explored two research questions: why do individuals decide to enter into elective co-parenting arrangements? And how do they manage their co-parenting arrangement and their relationship with their co-parent? Interview data from 10 elective co-parents (5 mothers and 5 fathers) were analyzed according to the principles of reflexive thematic analysis. Sociological theorisations of family practices, family display and family thinking were utilized to make sense of the data. The results centred around two organizing themes ('Reproducing the traditional family' and 'Modernising the traditional family'), and participants experienced a tension between these two ideas. Participants aimed to manage their co-parenting relationship with shared values and friendship, but defining their relationship was complex and gendered parenting patterns were ubiquitous. Findings add nuance to theorisations of family life and demonstrate that traditional parenthood ideologies remain pervasive, as parents aim to imagine and pursue parenthood on their own terms.

Asked to be a sperm donor: disclosure dilemmas of gay men living with HIV.

Previous research has documented the various challenges people living with HIV face as they navigate intimate relationships, including what is often referred to as disclosure. In studies of gay, bisexual and other men who have sex with men, the issue of telling or not telling others about an HIV-positive status has been examined primarily in relation to communication with sexual partners, with few studies focusing on other aspects of intimacy. Drawing on interviews with gay men living with HIV, conducted in four clinics in London, this article explores the narratives of men who have been asked by female friends about the possibility of being a sperm donor. The narratives highlight layers of complexity which have received little attention, not only in research on HIV but also in studies of sperm donation and co-parenting. The article advances dialogue between these two largely separate bodies of work. Our data suggest that reluctance to share an HIV-positive status with others can be an important factor in deciding how to answer the 'sperm donor question'. Examining reproductive relationships of a specific kind - those based on friendships between women and gay men - the article develops the understanding of how secrecy about HIV shapes intimate lives.

Maternal and co-parental experiences and satisfaction with a co-parenting breastfeeding eHealth intervention in Canada.

BACKGROUND: Suboptimal breastfeeding rates are a public health priority. Interventions that include both breastfeeding women and their co-parents can increase breastfeeding initiation, duration, and exclusivity. eHealth can be an effective means of designing such interventions, as parents increasingly use the internet to access health information. The objective of this study was to determine maternal and co-parent satisfaction with an eHealth intervention. METHODS: The study was part of a larger randomized controlled trial that took place in Canada between March 2018 and April 2020. Data was collected from mothers (n = 56) and co-parents (n = 47). INTERVENTION: The eHealth intervention group received: 1) continued access to an eHealth breastfeeding co-parenting resource from the prenatal period to 52 weeks postpartum; 2) a virtual meeting with a research assistant; and 3) 6 weekly emails reminders. Follow-up data were collected via online questionnaires completed at 2 weeks post enrollment and 4, 12, 26, and 52 weeks postpartum to determine use and satisfaction with the intervention components. FINDINGS: The majority of mothers and co-parents independently reviewed the eHealth resource (95% and 91%, respectively), with higher use in the prenatal period. Participants found the resource to be useful (92%), informative (93%), targeted both parents (90%), and easy to understand (97%). Participants indicated the resource was comprehensive, easily navigated, convenient, and engaging. APPLICATION TO PRACTICE: Providing mothers and their co-parents with breastfeeding co-parenting support via an eHealth intervention delivers accessible, comprehensive information which may assist them in meeting their breastfeeding goals.

[Representations of co-parenthood among primiparous and multiparous fathers-to-be]. / Représentations de la coparentalité des futurs pères primipares et multipares.

From the moment they become pregnant, future parents anticipate how they will coordinate, support and divide the tasks related to their child. This is known as co-parenting. Research carried out in three french gynaecology-obstetrics departments and in social network examined fathers' perceptions of co-parenthood and sought to determine whether these were in line with scientific conceptions of the concept.

TRUE Dads: The impact of a couples-based fatherhood intervention on family relationships, child outcomes, and economic self-sufficiency.

TRUE Dads, a federally funded Responsible Fatherhood intervention, aims to strengthen three of men's key roles in the family: (1) as fathers, building and maintaining positive engagement with their child; (2) as partners, maintaining a positive relationship with their co-parent; and (3) as providers, through fostering employment and economic self-sufficiency. A feature of the program is that low-income fathers and their co-parenting partners participate together in 6 3-hour group workshops, followed by optional participation in an additional 6 3-hour workshops. Fathers in the intervention condition were offered a chance to participate in a 2-week employment program. 1,042 co-parenting teams were recruited and randomly assigned to TRUE Dads' group intervention (60%) or a no-treatment control group (40%). In analyses of single measures, one year after study entry, compared with no-treatment controls, TRUE Dads program participants reported fewer depressive symptoms, less destructive couple communication and domestic violence, and increased employment for fathers. Using expanded latent variable measures of core constructs, Structural Equation Modeling revealed indirect effects of the intervention, in which reductions in both parents' negative symptoms and destructive couple communication were associated with (a) reductions in negative parenting qualities and children's behavior problems and (b) increases in fathers' economic self-sufficiency. Reducing parents' personal distress and improving relationship quality between co-parents appears to be important to enhancing fathers' positive family engagement. From a family policy perspective, the results suggest that integration rather than separation of healthy marriage, responsible fatherhood, and employment programs could provide synergistic power to programs designed to strengthen low-income families.

TRUE Dads, una intervención en la paternidad responsable financiada con fondos federales, tiene como finalidad fortalecer tres de los papeles fundamentales de los hombres en la familia: 1) como padres, construir y mantener un compromiso positivo con su hijo; 2) como compañeros de cocrianza, mantener una relación positiva con el otro padre; y 3) como proveedores, fomentar el empleo y la autonomía económica. Una característica del programa es que los padres de bajos recursos y sus compañeros de cocrianza participan juntos en 6 talleres grupales de 3 horas, y luego pueden participar de manera opcional en otros 6 talleres de 3 horas. A los padres del grupo de intervención se les ofreció una oportunidad de participar en un programa de empleo de dos semanas. Se convocó a 1042 equipos de cocrianza, los cuales fueron asignados aleatoriamente a una intervención grupal de TRUE Dads (60%) o a un grupo de referencia sin tratamiento (40%). En los análisis de medidas simples, un año después del ingreso en el estudio, en comparación con los integrantes del grupo de referencia sin tratamiento, los participantes del programa TRUE Dads informaron menos síntomas depresivos, menos comunicación destructiva de pareja y violencia doméstica, y un aumento del empleo para los padres. Usando medidas variables latentes ampliadas de constructos centrales, el modelo de ecuación estructural reveló efectos indirectos de la intervención, en los cuales las reducciones en los síntomas negativos y la comunicación destructiva de la pareja en ambos padres estuvieron asociadas con (a) disminuciones de las cualidades negativas de crianza y de los problemas de conducta de los niños, y (b) aumentos de la autonomía económica de los padres. La reducción del distrés personal de los padres y la mejora de la calidad de la relación entre los copadres parece ser importante para mejorar el compromiso familiar positivo de los padres. Desde una perspectiva de política familiar, los resultados indican que la integración, en lugar de la separación de un matrimonio saludable, la paternidad responsable y los programas de empleo podrían aportar poder sinérgico a los programas diseñados para fortalecer a las familias de bajos recursos.

The Case for Multidimensional Co-Parenting Behaviors as Sources of Chronic Stress: Understanding Pathways to Mental Health Symptomology Among Divorced and Separating Adults.

The co-parenting relationship matters for postdivorce parental adjustment. This study explores the relative impact of different forms of co-parenting behaviors, coupled with an individual's psychological resources, in explaining parent mental health in recently divorced or separated parents (n = 355). A latent variable structural equation model was fit to examine pathways between dimensions of co-parenting (support, overt conflict, self-controlled covert conflict, and externally controlled covert conflict), various psychological resources (satisfaction with the divorce decree, perceived competence of the co-parent, and self-efficacy), and adverse mental health symptomology. Significant direct pathways were identified between overt co-parenting conflict and adverse mental health. Indicators of co-parenting quality were tied differentially to various resources. Indirect effects were found for both self-controlled covert conflict and overt conflict on adverse mental health symptomology through self-efficacy. Leverage points and considerations for health professionals and practitioners working with divorcing parents are discussed.

Experiences of intergenerational co-parenting during the postpartum period in modern China: A qualitative exploratory study.

Most studies conducted in the West on the role played by intergenerational families in co-parenting have focused mostly on families with a single mother or those in difficult circumstances, while little is known about the experiences of members of intergenerational intact families during the early postpartum period. This study aimed to explore the intergenerational co-parenting experiences of young parents and grandmothers in China, focusing on how they shared the responsibility of caring for the new mother and infant during the postpartum period. A total of 16 eligible intergenerational intact families, including 16 mothers, 15 fathers and 12 grandmothers, were interviewed. The data set was analysed using the approach of directed content analysis guided by Feinberg's Ecological Model of Co-parenting. The data were categorized into four themes: 'division of labour', 'postpartum and infant care agreement', 'support-undermining' and 'joint family management'. An additional theme, 'expressed a need for family support', emerged from the data on these intergenerational families. The findings emphasize the importance of intergenerational co-parenting relationships in families where two generations co-parent the newborn together.

Children's Adjustment to Parents' Break Up: The Mediational Effects of Parenting and Co-parenting.

Although past studies have shown an association between union instability (i.e., change in family structure) and children's aggressive behaviors, the mechanism by which this occurs is less understood. This study (n = 3,387) examined whether father and mother involvement, co-parenting support, and maternal responsiveness explained the association between union instability in early life and children's aggressive behaviors at 9 years, and whether relationship status moderated this association. Findings reveal that only co-parenting support mediated this association and only for children whose mothers divorced (not for mothers who experienced a non-marital separation), suggesting that when a divorce occurs, the relationship between partners (co-parenting) is more important than the relationship with children (parenting) for children's social adjustment.

Family Change and Co-parenting in Resident Couples and Children's Behavioral Problems.

Using data from the Fragile Families and Child Wellbeing study (n = 1,553), the present study examined whether father involvement and co-parenting quality mediated the association between union instability (number of residential romantic partner changes) over the first 5 years of life and children's externalizing problem behaviors (EPB) at 5 years. The results indicate that only co-parenting support mediated the association between union instability and children's EPB, controlling for known covariates of children's EPB. The findings suggest that the union instability associated with romantic partner transitions has a deleterious effect on children's behaviors because the change in union status decreases the quality of the co-parenting relationship.

Developing a Prenatal Couple Education Program Focusing on Coparenting for Japanese Couples: A Quasi-Experimental Study.

Having and raising children can be a source of joy for parents. However, the transition to parenthood is associated with a certain degree of strain and stress, and couple relationship quality often declines during the transition. Coparenting, the shared responsibility of childrearing, benefits both parents and children and is an important aspect of the transition to parenthood. In this quasi-experimental study, we aimed to develop a couple education program in Japan that focuses on coparenting among couples expecting their first child. Twenty-one healthy couples voluntarily participated in the intervention group (n = 16) or the control group (n = 5). Couples in each group could voluntarily participate in standard childbirth education classes. The intervention was a couple education program designed to enhance coparenting and consisted of two interactive classes, including discussions within each couple and watching a short video showing an example of childrearing. We collected outcome measures on childrearing, couple relationship, parental mental health, and child adjustment at 1 month and 3 months after childbirth. Multiple regression analysis was performed and showed positive effects of the intervention on childrearing and child adjustment. Being in the intervention group had a significant positive effect on Coparenting Support scores at 1 month after childbirth (ß = 0.457, p < 0.003, R2 = 0.187) and Soothability scores for child adjustment at 3 months after childbirth (ß =0.429, p < 0.006, R2 = 0.157). In conclusion, we have developed the prenatal education program focusing on coparenting for Japanese couples.

Is Variation in Biological and Residential Ties to Children Linked to Mothers' Parental Stress and Perceptions of Coparenting?

Mothers with children from prior relationships or with stepchildren may perceive greater challenges in parenting than their counterparts in less complex families. We use the Families and Relationships Study (FRS) to analyze parental stress and perceptions of co-parenting among cohabiting and married mothers with resident minor children (N = 679). Compared to mothers with only shared children, parental stress and perceptions of co-parenting generally do not differ when mothers have children from prior unions. However, mothers with resident stepchildren evaluate the distribution of childcare as less fair, consider their partners as less reliable co-parents, and rate their partner more poorly as a co-parent relative to those with no stepchildren. These findings suggest that creating a stepfamily through one's own children may not present additional parenting challenges or stressors whereas having stepchildren introduced through a partner may be linked to a different, and less positive, parenting experience.

Co-parenting and feeding in early childhood: Reflections of parent dyads on how they manage the developmental stages of feeding over the first three years.

Family-level influences on the development of healthy eating behaviors start in infancy and toddlerhood with how families manage developmental stages of feeding. Little research on home feeding environments for young children has examined how mothers and fathers collaborate around feeding issues or contribute jointly to feeding. The purpose of this qualitative study is to examine co-parenting with regard to infant/toddler feeding practices. Twenty-four sets of co-resident, biological parents with a child between 6 months and 3 years were interviewed together about their feeding practices and how they discussed and collaborated on feeding during the main stages of feeding development in the first three years. Analyses illuminate themes related to how specific domains of co-parenting (satisfaction with labor, support, agreement, conflict) factor into infant and toddler feeding as well as how additional factors such as having older children and employment schedules shape how both food parenting practices and co-parenting are managed in relation to feeding. Mothers were the primary managers of feeding labor. Fathers participated in feeding in different ways and levels starting in infancy and increased involvement in feeding over the first few years requiring an ongoing negotiation around co-parenting related to feeding. Overall, this study develops insights into how multiple caregivers construct a family environment specifically related to early feeding - a perspective missing from current conceptualizations of home feeding environment. Attention to the concept of co-parenting within home feeding environments should help inform more effective approaches to intervene with families on issues around childhood obesity and family health.

'Friendly allies in raising a child': a survey of men and women seeking elective co-parenting arrangements via an online connection website.

STUDY QUESTION: What are the characteristics, motivations and expectations of men and women who search for a co-parent online? SUMMARY ANSWER: Male and female prospective co-parents differed in terms of their motivations, choice of co-parent and expectations of co-parenting, while differences according to sexual orientation were less marked. WHAT IS KNOWN ALREADY: Very few studies have addressed the experiences of elective co-parents, i.e. men and women who are not in a relationship with each other creating and raising a child together. No study has examined the motivations and experiences of those who seek co-parents online. STUDY DESIGN, SIZE AND DURATION: An online survey was completed by 102 participants (61 men, 41 women) who were members of Pride Angel, an online connection website that facilitates contact between people looking for someone with whom to have a child. The survey was live for 7 weeks. PARTICIPANTS/MATERIALS, SETTING, METHODS: Details of the survey were emailed to all members of Pride Angel. The survey obtained data on participants' demographic characteristics, motivations, choice of co-parent and expectations of co-parenting. Data were analysed to examine differences by gender and by sexual orientation within each gender. MAIN RESULTS AND THE ROLE OF CHANCE: Approximately one-third of men and one half of women seeking co-parenting arrangements were heterosexual. The majority (69, 68%) of participants were single, although significantly more gay and bisexual men (15, 36%) and lesbian and bisexual women (11, 55%) had a partner compared with heterosexual men (4, 20%) and heterosexual women (2, 12%), respectively. Overall, the most important motivation for seeking co-parenting arrangements was in order for both biological parents to be involved in the child's upbringing. Co-parents were looking for someone with a good medical history. Most female co-parents expected the child to live with them, whereas male co-parents either wished the child to reside with the mother or to live equally in both households. A higher proportion of gay and bisexual men than heterosexual men wanted daily contact with the child. LIMITATIONS, REASONS FOR CAUTION: Although this study presents data from the largest sample of elective co-parents to date, the main limitations were the low response rate and that only members of one website were approached. The findings may not be representative of all potential elective co-parents. WIDER IMPLICATIONS OF THE FINDINGS: This study provides important insights into the new phenomenon of elective co-parenting. With the increasing use of assisted reproductive technologies and the diversification of family forms, a growing number of people are seeking co-parenting arrangements to have children. While up until now, elective co-parenting has been principally associated with the gay and lesbian community, this study shows that, with the rise of co-parenting websites, increasing numbers of heterosexual men and women are seeking these types of parenting arrangements. This study generates the first findings on the expectations and motivations of those who seek co-parents online and examines whether these differ according to gender and sexual orientation. Future studies are needed to assess the impact of this new form of parenting on all involved, particularly the children. STUDY FUNDING/COMPETING INTERESTS: This study was supported by the Wellcome Trust (097857/Z/11/Z). Erika Tranfield is the co-founder of the website Pride Angel, the remaining authors have no conflicts of interest to declare.

Fathers and Asthma Care: Paternal Involvement, Beliefs, and Management Skills.

OBJECTIVE: To compare asthma care roles of maternal and paternal caregivers, and examine associations between caregiver involvement and the outcomes of adherence, morbidity, and parental quality of life (QoL). METHODS: Mothers and fathers in 63 families of children, ages 5-9 years, with persistent asthma completed semistructured interviews and questionnaires. Adherence was measured via electronic monitoring. Paired t tests compared parental asthma care roles, and analysis of covariance, controlling for socioeconomic status, evaluated associations of asthma outcomes with caregiver involvement scores. RESULTS: Mothers had higher scores on measures of involvement, beliefs in medication necessity, and on four subscales of the Family Asthma Management System Scale interview (Asthma Knowledge, Relationship with Provider, Symptom Assessment, and Response to Symptoms). Maternal QoL was lowest when both maternal and paternal involvement was high. Paternal involvement was associated with increased morbidity. CONCLUSIONS: There is room for enhancement of fathers' asthma care roles. Higher levels of paternal involvement may be driven by family need.

Co-Parenting Relationship Experiences of Black Adolescent Mothers in Active Romantic Partnerships With the Fathers of Their Children.

We conducted an interpretive description of co-parenting relationship experiences of romantically involved Black adolescent mothers and fathers with shared biological children. The study was conducted in Brooklyn, New York, using data from individual in-depth interviews with adolescent mothers and fathers (n = 10). Four themes were identified: (a) putting our heads together; (b) balancing childhood and parenthood; (c) less money, more problems; and (d) if we use condoms, it is for contraception. The co-parenting couples managed very complex relationships, but their mutual interest in the welfare of their children was a relational asset. Co-parents had sparse financial resources but used a moral economy strategy to provide mutual support. Future research is needed that focuses on identifying other co-parent relationship assets and integrating and evaluating their utility for enhancing interventions for adolescent families.

The effect of communication change on long-term reductions in child exposure to conflict: impact of the promoting strong African American families (ProSAAF) program.

African American couples (n = 331) with children, 89% of whom were married, were assigned to either (a) a culturally sensitive couple- and parenting-enhancement program (ProSAAF) or (b) an information-only control condition in which couples received self-help materials. Husbands averaged 41 years of age and wives averaged 39 years. We found significant effects of program participation in the short term on couple communication, which was targeted by the intervention, as well as over the long term, on self-reported arguing in front of children. Long-term parenting outcomes were fully mediated by changes in communication for wives, but not for husbands. For husbands, positive change depended on amount of wife reported change. We conclude that wives' changes in communication from baseline to posttest may be more pivotal for the couples' long-term experience of decreased arguing in front of children than are husbands' changes, with wives' changes leading to changes in both partners' reports of arguments in front of children.

Mothers' Perceived Co-Parenting and Preschooler's Problem Behaviors: The Mediating Role of Maternal Parenting Stress and the Moderating Role of Family Resilience.

Introduction: Problem behaviors in preschoolers signals social adjustment challenges. This study investigates the mediating role of parenting stress in the relationship between co-parenting and these behaviors, and examines how family resilience impacts this dynamic. Methods: A detailed survey was conducted with 1279 mothers of 3-6-year-olds in Shanghai, China, focusing on co-parenting, family resilience, parenting stress, and children's behaviors. We employed SPSS 26 for initial tests and the Hayes PROCESS macro in SPSS 23.0 for advanced analysis, using bootstrap methods to assess mediation and moderation effects. Results: The analysis revealed that maternal parenting stress mediates the relationship between co-parenting and children's problem behaviors. Specifically, unsupportive co-parenting or low levels of supportive co-parenting heightened maternal stress, which in turn increased children's problem behaviors. Family resilience was found to moderate this relationship, buffering the impact of unsupportive co-parenting on maternal stress. High family resilience levels were associated with lower parenting stress, regardless of co-parenting quality. Conclusion: These findings highlight the importance of enhancing family resilience and supportive co-parenting to mitigate parenting stress and reduce problem behaviors in children. It has practical implications for developing family-centred interventions and policies to strengthen family resilience and co-parenting skills.

The Effect of Paternal Co-Parenting on Preschool Children's Problem Behaviors: The Chain-Mediating Role of Maternal Parenting Burnout and Psychological Aggression.

Objective: With the social changes, a growing number of women have joined the workforce, leading to a shift in the traditional roles of child-rearing. There has been a growing focus on the significance of fathers' roles in child development, particularly the influence of fathers on children's problematic behaviors, making it an increasingly prominent issue. However, there is limited understanding regarding the potential mechanisms through which fathers may exert influence on children's problem behaviors. To address this gap, this study sought to investigate the link between paternal co-parenting and preschool children's problem behaviors, and the mediating effects of maternal parenting burnout and psychological aggression. Methods: This study used the Personal Information Form and four scales to administer questionnaires to 1164 mothers of preschool children (Mage = 4.26 ± 0.85) in Guangdong Province, China. The collected data underwent processing and analysis using SPSS 22.0. Results: Paternal co-parenting demonstrated a significantly positive correlation with problem behaviors among preschool children. The impact of paternal co-parenting on children's problem behaviors was mediated by maternal parenting burnout, maternal psychological aggression, and the combined effect of maternal parenting burnout and psychological aggression. Conclusion: Maternal parenting burnout and maternal psychological aggression play a sequential mediating role between paternal co-parenting and problem behaviors among preschool children. This study revealed the internal mechanism through which paternal co-parenting influenced problem behaviors exhibited by children. It provides some evidence to support the important role of fathers in child development, and provides a reference for policymakers and educators to develop interventions for children's problem behaviors.

Co-Parenting Impact on Breastfeeding: Systematic Review and Meta-Analysis.

Background: Although the beneficial effects of exclusive breastfeeding (EBF) on infants and mothers have been identified, EBF rates remain unsatisfactory. Co-parenting interventions for perinatal couples have not been systematically evaluated and analyzed for their effects on breastfeeding outcomes. Aims and Objectives: To systematically evaluate the effects of co-parenting interventions on the rate of EBF, breastfeeding knowledge, breastfeeding attitude, breastfeeding self-efficacy, parental relationship, and partner support. Methods: Randomized controlled trials and quasi-experimental studies were systematically screened in eight online databases from inception to November 2022. Trials included in this review were assessed using the Cochrane Risk of Bias Assessment Tool. Eligible trials were used to conduct a meta-analysis using Review Manager software. The I2 statistic was used to assess heterogeneity between studies. When it was not possible to conduct a meta-analysis, a descriptive analysis was used to present the findings due to insufficient data from the included studies. Results: Fifteen of the 1,869 articles reviewed met the inclusion criteria. Co-parenting interventions significantly improved the EBF rate at 16 weeks (odds ratio [OR] = 3.85, 95% confidence interval, CI [1.84 to 8.03], p < 0.001, I2 = 69%) and 6 months (OR = 2.82, 95% CI [1.47 to 5.41], p = 0.002, I2 = 85%). This study revealed that co-parenting interventions made statistically significant improvements in parental relationship (standardized mean difference [SMD] = 0.26, 95% CI [0.13 to 0.38], p < 0.001, I2 = 80%). There was no evidence of the effectiveness of interventions in terms of overall parental support (SMD = 0.75, 95% CI [-0.46 to 1.97], p < 0.001, I2 = 96%). Given the discrepant and limited research data, findings on breastfeeding knowledge, breastfeeding attitudes, and breastfeeding self-efficacy were presented descriptively. Conclusion: Co-parenting interventions effectively increase EBF rates at 16 weeks and 6 months postpartum, and improve breastfeeding knowledge, breastfeeding attitude, and parental relationships.
