Pregnancy is linked to faster epigenetic aging in young women.

A central prediction of evolutionary theory is that energy invested into reproduction comes at the expense of somatic maintenance and repair, accelerating biological aging. Supporting this prediction are findings that high fertility among women predicts shorter lifespan and poorer health later in life. However, biological aging is thought to begin before age-related health declines, limiting the applicability of morbidity and mortality for studying the aging process earlier in life. Here, we examine the relationship between reproductive history and biological aging in a sample of young (20 to 22yo) men and women from the Cebu Longitudinal Health and Nutrition Survey, located in the Philippines (n = 1,735). We quantify biological aging using six measures, collectively known as epigenetic clocks, reflecting various facets of cellular aging, health, and mortality risk. In a subset of women, we test whether longitudinal changes in gravidity between young and early-middle adulthood (25 to 31yo) are associated with changes in epigenetic aging during that time. Cross-sectionally, gravidity was associated with all six measures of accelerated epigenetic aging in women (n = 825). Furthermore, longitudinal increases in gravidity were linked to accelerated epigenetic aging in two epigenetic clocks (n = 331). In contrast, the number of pregnancies a man reported fathering was not associated with epigenetic aging among same-aged cohort men (n = 910). These effects were robust to socioecological, environmental, and immunological factors, consistent with the hypothesis that pregnancy accelerates biological aging and that these effects can be detected in young women in a high-fertility context.

The intersection between alexithymia, testosterone reactivity, and coparenting in fathers predicts child's prosocial behavior.

The development of prosocial skills in children is a key predictor of long-term social, cognitive, and emotional functioning. However, the role of fathers' psychological characteristics in fostering prosocial development, including during the prenatal period, and the mechanisms underlying their influence, remain relatively unexplored. This study aimed to examine whether a higher tendency of alexithymia, a difficulty to identify and verbalize emotions, in expectant fathers predicts prosocial behavior of two-year-old toddlers through the quality of coparenting and whether greater testosterone increase during a stressful parenting task moderates this indirect effect. A sample of 105 couples and their children was tracked longitudinally starting from the third trimester of pregnancy (T1), at three months (T2), and at two years postnatally (T3). Using self-report questionnaires, fathers reported on alexithymia (T1) and mothers and fathers reported on coparenting quality (T2). Additionally, fathers provided saliva samples before and after engaging in a stressful parenting task (the Inconsolable Doll Task) to measure testosterone reactivity (T1). Children's prosocial behavior was observed during an out-of-reach task (T3). A moderated mediation analysis using structural equation modeling showed that higher levels of alexithymia pre-birth predicted lower coparenting quality three months after birth, which in turn predicted lower prosocial behavior of two-year-old children, but only among fathers with mean or high testosterone increases. This study illuminates a potential mechanism by which fathers' alexithymia and testosterone reactivity forecast their toddlers' prosocial behavior.

The cuckoldry conundrum.

Concerns about cuckoldry are a dominant theme in evolutionary studies of mating, frequently used to explain sex differences in reproductive strategies. However, studies in nonhuman species have shown that cuckoldry can be associated with important benefits. These insights have not been well integrated with the human literature, which continues to focus on anticuckoldry tactics and negative repercussions for men. I evaluate two key assumptions central to human models of cuckoldry: (1) men are being tricked into investing in nonbiological offspring and (2) investment in nonbiological offspring is wasted. The ethnographic data on fatherhood shows that the concepts of pater and genitor are complex and locally constructed ideas that often include explicit knowledge of extra-pair paternity, countering the idea that nonpaternity results from trickery. Furthermore, rather than being a "waste," paternity loss can be associated with important gains for men, helping to explain why men invest in nonbiological offspring.

First-time fathers show longitudinal gray matter cortical volume reductions: evidence from two international samples.

Emerging evidence points to the transition to parenthood as a critical window for adult neural plasticity. Studying fathers offers a unique opportunity to explore how parenting experience can shape the human brain when pregnancy is not directly experienced. Yet very few studies have examined the neuroanatomic adaptations of men transitioning into fatherhood. The present study reports on an international collaboration between two laboratories, one in Spain and the other in California (United States), that have prospectively collected structural neuroimaging data in 20 expectant fathers before and after the birth of their first child. The Spanish sample also included a control group of 17 childless men. We tested whether the transition into fatherhood entailed anatomical changes in brain cortical volume, thickness, and area, and subcortical volumes. We found overlapping trends of cortical volume reductions within the default mode network and visual networks and preservation of subcortical structures across both samples of first-time fathers, which persisted after controlling for fathers' and children's age at the postnatal scan. This study provides convergent evidence for cortical structural changes in fathers, supporting the possibility that the transition to fatherhood may represent a meaningful window of experience-induced structural neuroplasticity in males.

The prevalence of adolescent fatherhood and its associated factors in East African countries.

BACKGROUND: In developing nations, the phenomenon of adolescent fatherhood poses significant challenges, including increased risk of poverty, limited educational opportunities, and potential negative health outcomes for both the young fathers and their children. However, an overwhelming majority of research has concentrated on teenage motherhood. Adolescent fatherhood in poor nations has been the subject of little research. Few public health initiatives address adolescent fatherhood, in contrast to adolescent motherhood. Although there is currently more being done in industrialized nations to recognize adolescent fatherhood in clinical settings and the academic community. Undeveloped nations such as East Africa still have more problems that need to be resolved. Therefore, this study aimed to investigate the prevalence of and factors contributing to adolescent fatherhood in East Africa. METHODS: Data from the Demographic and Health Surveys (DHS), collected between 2011 and 2022 in 12 East African nations, were used in this analysis. For a weighted sample of 36,316 male adolescents aged 15-24 years, we examined variables, as well as the prevalence of adolescent fatherhood. Univariate and multivariable logistic regression analyses were performed to identify candidate factors and significant explanatory variables associated with the outcome variable. The results are presented using adjusted odds ratios (AORs) at 95% confidence intervals (CIs). P values of ≤ 0.2 and < 0.05 were used to investigate statistically significant factors in the univariate and multivariable logistic regression analyses, respectively. RESULTS: The overall prevalence of adolescent fatherhood was 11.15% (95% CI = 10.83,11.48) in East Africa. Age at first sex 20-24 years (AOR = 0.44, 95% CI:0.41,0.48), age-20-24 years old (AOR = 17.03,95% CI = 15.01,19.33), secondary/higher education (AOR = 0.57, 95% CI = 0.49,0.67), poor wealth (AOR = 2.27, 95% CI = 2.05,2.52), middle wealth (AOR = 1.70, 95% CI = 1.51,1.90), employed (AOR = 3.92, 95% CI = 3.40,4.54), utilized modern contraceptives (AOR = 0.75, 95% CI = 0.69,0.81), and female household heads (AOR = 0.43, 95% CI = 0.39,0.48) were associated with adolescent fatherhood. CONCLUSIONS: Adolescent fatherhood is more prevalent, in East Africa. These findings highlight the complexity of adolescent fatherhood and suggest that multiple factors, including socio-demographic characteristics and reproductive health behaviors, play a role in determining the likelihood of becoming an adolescent father. Understanding these associations can inform targeted interventions and policies aimed at reducing adolescent fatherhood rates and addressing the specific needs and challenges faced by young fathers in East Africa. Further research and interventions should focus on promoting education, economic opportunities, and access to modern contraceptives, while also addressing gender dynamics and social norms that contribute to adolescent fatherhood in the region.

Fatherhood timing and men's midlife earnings: A within-family study of Finnish cohorts born in 1938-50.

Fathers tend to achieve higher earnings than childless men, but there is limited evidence on the associations between fatherhood timing and men's later earnings. Using a longitudinal census-based sample of Finnish men, including a subsample of brothers, we investigated fatherhood timing and men's midlife earnings using both between- and within-family models. Earnings around age 50 were lower among adolescent and young fathers than for men who became fathers at ages 25-29 or later, but these associations became negligible after accounting for measured confounders and unobserved familial confounding. Overall, our findings highlight the important roles of selection into early childbearing and into childlessness. At the population level, early fatherhood was associated with clear negative distributional shifts in fathers' midlife earnings. However, among all men, any influence of fatherhood timing on men's midlife earnings distribution paled in comparison with that of childlessness.

Fathers' contributions to attachment in adolescence and adulthood: the moderating role of race, gender, income, and residential status.

Fathers play a critical yet underappreciated role in adolescent development. To examine contributions of fathers' parenting to attachment in adolescence and adulthood, this longitudinal study followed 184 adolescents from ages 13-24. At age 13, adolescents reported on their fathers' parenting behavior and were observed in a father-teen conflict task; at ages 14 and 24, they completed the Adult Attachment Interview. Adolescents who lived with their father showed higher attachment security at age 14 (Cohen's d = .72), compared to those with non-residential fathers. Fathers' positive relatedness and support for teens' psychological autonomy predicted attachment security at age 14. Fathers' physical aggression predicted attachment insecurity in adolescence, whereas fathers' verbal aggression predicted insecurity in adulthood, illuminating developmental shifts. Pathways to security were moderated by father residential status, adolescent gender, and race. Findings underscore the importance of fathers' presence, autonomy support, and non-aggression in predicting adolescents' state of mind in close relationships.

Elevating Black fathers' experiences in the National Fatherhood Initiative: Strengths and areas for improvement of 24/7 Dad® curriculum and case management services.

The Healthy Marriage and Responsible Fatherhood grant program is one of the most robust mechanisms supporting fatherhood programming in the United States, with the gold standard of care including fatherhood curriculum (e.g., 24/7 Dad®) and case management services. Despite the fact that fatherhood in the United States is not a monolith and Black fathers make up over 40% of those served through Responsible Fatherhood (RF) program, little research explicitly centers the lived experiences of low-income Black fathers. The current study used focus groups with fathers (n = 23) and staff (n = 8) enrolled in a RF grantee program. Thematic analysis was used to determine programmatic mechanisms supporting these fathers' success and areas for improvement. Our findings highlight that the creation of a "safe space" by facilitators and the power of the group dynamic were essential elements for fathers' success overall. We also identified numerous programmatic mechanisms supporting Black fathers' success specific to fathering, healthy relationships, and economic stability. Finally, we highlighted important limitations that may impede the success of low-income, Black fathers related to the 24/7 Dad® curriculum, engagement efforts, and economic stability, and discuss related practice, policy, and research recommendations.

Searching for who benefits most and least: An analysis of moderators of the TRUE Dads fatherhood intervention.

Evaluations of interventions to promote fathers' involvement in family life typically focus on whether or not the intervention has a positive impact. Some evaluations also attempt to describe mediators that explain how the intervention is linked to specific outcomes. An evaluation of TRUE Dads, a Randomized Clinical Trial of a couples-based fatherhood intervention for low-income families, reported results that addressed these two issues. Reporting new analyses, the present study addresses a question asked in only a very few fatherhood intervention studies: Are there moderator variables that define characteristics of participants who benefit most or least from the intervention? A total of 46 potential moderators of 2 significant intervention outcomes - reductions in personal distress and in negative evaluations of the parents' relationship with each other - were selected from a 5-domain risk/protective model of family functioning (Cowan & Cowan, 2018. Journal of Family Theory & Review, 92, 111) and from a set of demographic variables associated with these outcomes. An additional 24 potential moderators were tested on 4 outcomes that did not have direct intervention effects. Only 6 of the 70 moderator tests were statistically significant. The intervention provided greater reductions in parents' personal distress when fathers had more economic resources, co-parents had higher levels of education, and the parents were living in the same household on entering the study. There were greater reductions in negative aspects of their couple or co-parenting relationship when the parents at enrollment described more difficulties in the parent-child relationship, fathers were more involved in the children's daily care and were living in the household with their child. No other moderators were found. The results support the conclusion that TRUE Dads was equally effective for a relatively wide range of participants. This search for potential moderators of TRUE Dads outcomes is presented as an example of a needed direction in the evaluation of fatherhood interventions.

Fathers' experiences with supportive parenting interventions: A qualitative systematic review.

Despite proven efficacy, fatherhood interventions face challenges in attracting and retaining participants. This qualitative systematic review aims to inform the future design of fatherhood interventions by consolidating and synthesizing the evidence around fathers' experiences with interventions aimed at enhancing their involvement and relationships with their children. Following PRISMA guidelines, we analyzed 10 studies from a search of six electronic databases. Our analysis coalesced into three pivotal themes: (a) creating a sense of belonging: facilitating participation; (b) transformative takeaways; and (c) challenges of negotiating expectations of masculinity. Our findings indicate that group-based, culturally sensitive programs are advantageous but also reveal that fathers grapple with reconciling evolving fatherhood roles with societally entrenched expectations of masculinity. This review offers actionable insights for the future development, evaluation, and implementation of fatherhood interventions, particularly those utilizing qualitative research methodologies.

Couple relationship functioning and social adjustment during the transition to parenthood among fathers with a history of maltreatment.

Study of fathers has gained significant traction over recent decades. However, the experience for men over the transition to parenthood remains focused on high-socioeconomic and socially advantaged fathers. Researchers have yet to thoroughly investigate how fathers may uniquely experience this transition period with a history of childhood maltreatment, given that childhood abuse is known to impact several components of development and relationship functioning into adulthood. The current study endeavored to fill this gap by evaluating the associations between fathers' childhood experiences of physical and emotional abuse and their relationship functioning over the transition to parenthood in terms of both the couple relationship and social adjustment in relationships with others. Using data from 399 fathers who participated in a randomized control trial during pregnancy, the results from stepwise regressions indicate fathers with a history of emotional abuse experience particular declines in their external relationships (reductions in social support and increases in social stress) from prenatal (Wave 1) to postpartum (Wave 2) reports. However, no significant association emerged between fathers' history of maltreatment and their relationship functioning with their partners. These results underscore the importance of investigating the impact of different types of abuse on men in fatherhood. Moreover, we emphasize the need to study further fathers' social adjustment over the transition to parenthood beyond the couple relationship and broad social support to address the needs of men with a history of maltreatment in their new role as fathers.

Feelings, thoughts and experiences of fathers in the early postpartum period: a phenomenological study.

AIMS/BACKGROUND: Transition to parenthood is a complex and challenging situation not only for mothers but also for fathers. In this process, fathers' feelings, thoughts and experiences are very important. This study aims to understand fathers' feelings, thoughts and experiences in the early postpartum period. DESIGN/METHODS: The descriptive phenomenological design was used in this study. Data were collected from 13 fathers through in-depth interviews. The content analysis method was used in data analysis. RESULTS: The following three themes were identified regarding the experiences of fathers in the early postpartum period: 'need for support', 'difficulties of being a father' and 'recommendations'. The fathers had more needs and inadequate support in their transition to the fatherhood role. CONCLUSION: All these results suggest that they faced many challenges in the early postpartum period. Sleep deprivation, being tired, having a restricted social life and increased responsibilities, and experiencing postpartum psychological fluctuations were some of these difficulties. In order to overcome these difficulties, they needed financial and moral support. The fathers who participated in the present study stated that they did not receive enough training and support from healthcare professionals. Healthcare professionals should keep in mind that not only of mothers and babies but also of fathers have needs to be met.

Men, mindsets and birth: results of a prospective longitudinal study.

AIMS/BACKGROUND: In recent years, there has been an increased interested in the contribution of fathers to childbirth. In the present paper we explore whether the father's birth-related mindset (being either more natural or more medical) can predict the mother's labour and birth outcomes and whether the father's experience and evaluation of the birth can predict his psychological well-being after the birth. DESIGN/METHODS: We conducted a longitudinal study (N = 304 expecting fathers) spanning the first trimester of pregnancy up to six months after birth. RESULTS: The study results could be integrated into a Single Indicator Model. They indicated that a father's more natural birth-related mindset predicted low-intervention birth for the mother. A low-intervention birth led to a more positive birth experience for the father, and in turn to better postpartum adjustment, fewer symptoms of postpartum paternal depression eight weeks after birth, and more secure bonding to the infant six months after birth. CONCLUSION: The study results indicate that fathers do not take a merely passive role in childbirth. On the contrary, analogous to pregnant mothers, fathers' views about childbirth might contribute to the course of birth, and their own postpartum psychological well-being. The results of the present study, thus, highlight the importance of fathers for childbirth and in a broader sense, the results also contribute to a better understanding of the psychological framework of birth and represents a valuable starting point for further research.

Parenthood, earnings, and the relevance of family formation sequences.

Prior research sheds little light on how shifts in family formation trajectories have implications for recent cohorts' earnings gains and losses with childbearing. Using longitudinal data from a contemporary cohort, we examine how the pay premium or penalty for parents varies by their relationship status at childbirth and subsequent changes in the status. Fixed effects models show that children born to unpartnered women are associated with substantial pay penalties for the mothers. Conversely, women giving birth within cohabiting or marital unions experience small or no motherhood penalties. For residential fathers, only children born after marriage are linked to pay increases. Men having children while cohabiting or unpartnered receive no fatherhood premiums even if they later transition into marriage. Married mothers' earnings outcomes also depend on their sequence of marriage and childbearing. Whereas women bearing children before marriage encounter a substantial motherhood penalty, those doing so after marriage face none. The variation in parenthood penalties or premiums by childbearing context cannot be entirely elucidated by the differences in the age of entering parenthood, ethnoracial composition, education, or pre-parenthood earnings growth rate among people having children in various contexts. We suggest that the family formation sequence is related to individuals' expectations and the support they receive for their parental roles, which shape parenthood earnings outcomes.

[Caregiving Experience With a Young Father With Multiple Myeloma Undergoing Renal Dialysis and Autologous Stem Cell Transplantation].

This case report addresses the author's experience providing nursing care to a 37-year-old patient diagnosed with multiple myeloma requiring regular renal dialysis due to disease progression who received autologous stem cell transplantation. The patient was diagnosed with cancer in young adulthood and, as a father figure, faced various psychological issues associated with the unexpected challenges encountered during their treatment phase. Psychosocial health, which is closely associated with quality of life in patients with cancer, has gained increasing attention in recent years. The limited research published on the subject of fathers diagnosed with cancer encouraged the author to detail her experience with this case. The care period was from August 5th to August 19th, 2022. During the care period, the Gordons's 11 functional health assessment was applied, with potentially severe infections, coping disorders, anxiety, potential risk of injury existing or potential nutritional deficiencies, oral mucosal changes, and diarrhea identified as the primary health problems of concern. Nursing interventions applied included providing protective isolation measures to prevent post-transplant infection, helping the patient learn effective ways to cope with emotional distress, and providing comprehensive follow-up care information and health education to alleviate the anxiety associated with hospital discharge and life after discharge. The challenges of providing nursing care to adolescent and young adult patients differ significantly from those faced in the care of either elderly or pediatric patients. Furthermore, although extensive research has been conducted on mothers diagnosed with cancer, little research has addressed the impact on the paternal role when fathers are diagnosed with cancer, with limited information available regarding their psychological concerns and issues or the impact on family dynamics. The author hopes this case care experience offers an insightful reference and guide for nursing practice that contributes to a better understanding of the psychological aspects of young adult fathers diagnosed with cancer and facilitates more appropriate care in clinical settings.

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.

Opportunities and Risks of Gender-Stereotypical Approach to Men in the Context of Education and Counselling Work Using the Example of Birth Preparation for Expectant Fathers At first glance, it seems absurd that families or mothers and fathers become addressees of social work when they decide to have a child. But the legislator has also formulated it: "Mothers and fathers as well as pregnant women and expectant fathers should be offered advice and help in questions of partnership and the development of parental parenting and relationship skills" (§16 paragraph 3 SGB VIII). One can argue that this makes sense, especially in complex and challenging times. Fathers in particular are confronted with an increasing ambivalence between caring father and providing breadwinner. Against the background of crisis-ridden conditions, this ambivalence can be perceived as strenuous living conditions, so that the addressing of social work is justified. Gender-homogeneous psychosocial services for fathersto- be make counselling and educational processes in the sense of helping them to help themselves be used by the addressees. In this article, the gender-stereotypical addressing of men in the context of education and counselling services is presented and discussed using the example of gender-homogeneous birth preparation courses for expectant fathers, on the basis of empirical findings.

Fatherhood and high-risk pregnancy: a scoping review.

BACKGROUND: The experience of expectant parenthood is commensurate of relative angst and nervousness albeit one of overall excitement and joy. However, when the pregnancy is regarded as high-risk, this experience changes dramatically for both parents. While literature on high-risk pregnancies is gaining traction, the focus is predominantly on the mother's experiences and therefore, a paucity exists in exploring the father's experiences of a high-risk pregnancy. This study aimed to determine the current extent of literature focusing on father's experiences of a high-risk pregnancy using a scoping review methodology. METHOD: Nine databases were reviewed using the EBSCOHost metadatabase: Academic Search Complete; APA PsychArticles; CINAHL Plus with full-text; Health Source: Nursing/Academic Edition; MasterFILE Premier; MasterFILE Reference eBook Collection; MEDLINE; SocINDEX with full-text; and eBook Collection. Data was extracted according to the following headings: Authors (including the year of publication); aim of the study; research context; research design; sample characteristics; and key findings. RESULTS: Fifteen studies were included in this review. A narrative synthesis was applied within which 4 key themes emerged from the data: (1) The father versus the healthcare professional and the hospital environment; (2) The impact of high-risk pregnancies on fathers; (3) Redefining the role of 'father' after experiencing high-risk pregnancy and (4) Focus on fathers: Recommendations for support during high-risk pregnancies. CONCLUSION: The findings of this study highlights the importance of the inclusion of men and fathers in supporting both his partner and (un)born child. The findings further illustrated the long-lasting impact of trauma felt by men which constrained his ability to support his family. A family-centred approach is needed to further support the family and the impact of a high-risk pregnancy on all members within the family unit.

A systematic review and narrative synthesis of fathers' (including migrant fathers') experiences of pregnancy and childbirth.

OBJECTIVE: The purpose of this review was to consider factors that influence the experiences of pregnancy and childbirth by fathers including migrant fathers. METHOD: A systematic review and narrative synthesis were conducted as per the PRISMA guidelines. The spider tool was used to build a search strategy which was used to conduct literature search in eight identified electronic databases: ASSIA, CINAHL, EMBASE, MEDLINE, PsycINFO, PUBMED, Sage and Scopus. Grey literature was searched through the King's Fund Library database, Ethos, The North Grey Literature Collection, Social Care Online and other charity websites such as the Refugee Council and Joseph Rowntree Foundation. The search was conducted across all the databases in the week commencing January 7, 2019, and restricted to studies published in the English language. RESULTS: The search across all the eight electronic databases identified 2564 records, 13 records through grey literature databases/websites and an additional 23 records identified through hand-searching/forward citation. The number of records after duplicates were removed was 2229. Record screening based on titles and abstracts identified 69 records for full text screening. Dual screening of these full text records identified 12 full records from 12 separate studies, eight of which were qualitative studies, three of which were quantitative studies and one mixed method study. FINDINGS: This review has revealed three main themes: influence of society and health professionals; adjustment to a new life of fatherhood; and involvement in maternity care. However, the literature has focused on non-migrant father's experiences of pregnancy and childbirth, with little attention paid to fathers who may be migrants. KEY CONCLUSION AND IMPLICATIONS FOR PRACTICE: This review has exposed a dearth of research on migrant fathers' experiences of pregnancy and childbirth in an era of increasing globalisation and migration between countries. Midwives and other health professionals should be alert to the needs of any father when providing maternity care. More research is needed which considers experiences of migrants and how choosing to move to a new country or being forced to move could influence migrant father's experiences and therefore their needs.

Father contribution to human resilience.

Fathers have been an important source of child endurance and prosperity since the dawn of civilization, promoting adaptation to social rules, defining cultural meaning systems, teaching daily living skills, and providing the material background against which children developed; still, the recent reformulation in the role of the father requires theory-building. Paternal caregiving is rare in mammals, occurring in 3-5% of species, expresses in multiple formats, and involves flexible neurobiological accommodations to ecological conditions and active caregiving. Here, we discuss father contribution to resilience across development. Our model proposes three tenets of resilience - plasticity, sociality, and meaning - and discussion focuses on father-specific contributions to each tenet at different developmental stages; newborn, infant, preschooler, child, and adolescent. Father's style of high arousal, energetic physicality, guided participation in daily skills, joint adventure, and conflict resolution promotes children's flexible approach and social competence within intimate bonds and social groups. By expanding children's interests, sharpening cognitions, tuning affect regulation, encouraging exploration, and accompanying the search for identity, fathers support the sense of meaning, enhancing the human-specific dimension of resilience. We end by highlighting pitfalls to paternal contribution, including absence, abuse, rigidity, expectations, and gender typing, and the need to formulate novel theories to accommodate the "involved dad."
