Recent decades have brought seismic shifts in how we parent. Dads today are far more hands-on than their own fathers or grandfathers ever were\u2014changing diapers in the middle of the night, juggling work with story time, and carving out precious paternity leave when they can. As I stroll around Brooklyn, New York, I see so many fathers pushing strollers and playing with their kids at the park. I\u2019m pretty sure this wouldn\u2019t have been the case a few decades ago. This evolution is wonderful in many ways.<\/p>\n
Fathers and mothers are different, and each bring unique benefits<\/a> to raising children. Dads often excel at rough-and-tumble play that builds resilience and confidence in kids, while modeling strength, respect to authority, problem-solving, and emotional steadiness. Moms, on the other hand, provide that irreplaceable nurturing core. Together, they create balance. But if we truly want fathers to stay deeply involved, we must take their unique challenges seriously instead of assuming they\u2019re fine as long as mom and baby are okay.<\/p>\n A groundbreaking study<\/a> published just last week in JAMA Network Open drives this point home. Researchers tracked more than one million fathers in Sweden whose children were born between 2003 and 2021. What they found is eye-opening: a father\u2019s risk for depression and stress-related disorders jumps by more than 30 percent toward the end of his child\u2019s first year. The risk actually decreases during pregnancy and the first few months postpartum, likely because everyone is in survival mode, laser-focused on the newborn. Anxiety and substance-related issues return to pre-pregnancy baselines by the one-year mark. And depression and stress? They spike later, when the initial adrenaline fades and the long haul of fatherhood truly sets in.<\/p>\n A father\u2019s risk for depression and stress-related disorders jumps by more than 30 percent toward the end of his child\u2019s first year.<\/p>\n Dr. Khatiya Moon, medical director for the collaborative care program at Northwell Health, put it perfectly in the NYPost<\/a>: \u201cScreening for mental health concerns in fathers is important and is something that isn\u2019t really done very much. Maybe if we did more screening, we\u2019d have more opportunity to catch fathers when they\u2019re struggling and support them.\u201d\u00a0<\/p>\n She notes that dads often slip into a purely supportive role early on, prioritizing mom and baby\u2019s vulnerability. That selflessness is noble, but it takes a toll. \u201cI wonder if that eventually gets more difficult to sustain,\u201d she said. Fathers also lack the community moms enjoy through prenatal appointments, mommy groups, and endless baby visits. No one really asks Dad seriously how he\u2019s sleeping or feeling. That needs to change, starting at home.<\/p>\n This isn\u2019t just about feelings, though. Did you know a man\u2019s biology also changes when he has a child? Science confirms it. Studies show that testosterone levels often drop<\/a> significantly in new fathers\u2014sometimes by 25 percent or more\u2014especially among those most involved in hands-on care like feeding, bathing, and playing.<\/p>\n Lower testosterone isn\u2019t a sign of weakness, but it does appear to shift a man\u2019s priorities away from competition or mating efforts toward nurturing. This makes sense. After all, we were biologically designed for family, and family was biologically designed to make communities less aggressive, more safe and unified.<\/p>\n Oxytocin, the \u201cbonding hormone,\u201d rises in dads too following a birth<\/a>, promoting physical closeness, emotional attunement, and that protective instinct we see when a father scoops up a hurt or crying baby. Cortisol, the stress hormone, spikes helpfully when dads hear infant cries (helping them respond fast) but drops during skin-to-skin contact or play, reinforcing positive caregiving loops.<\/p>\n Brain imaging reveals neuroplasticity in fathers as well\u2014structural and functional changes in areas tied to empathy, emotion regulation, and reward processing. These shifts happen through real-world father-infant interactions, not pregnancy hormones. In short, fatherhood literally rewires a man to be a better dad. The best version of himself for himself, his family and his community.<\/p>\n But when those changes collide with sleep deprivation, financial pressure, relationship strain, and societal expectations to \u201cman up,\u201d the result can be isolation, irritability, or full-blown depression. One study<\/a> even linked lower testosterone nine months postpartum with higher postpartum depression risk in dads, while very high levels sometimes correlated with hostility in the environment.<\/p>\n We ignore this at our own detriment.<\/p>\n
