The scientific study of the social practice of fathers parenting the children leads to interesting new information on hormones and brains, in addition to social aspects and the effects on children. An ideal story for the after-shadow of fathers' day.

As a father/grandfather I am conflicted over all these hormonal and brain changes. I don't know whether to lactate or have a hot flash...

pregnancy, childbirth, and fatherhood trigger a range of little hormonal shifts in the male body—but only if the father is in contact with the baby and the baby’s mother. When a child is born, Wynne-Edwards found, testosterone levels drop dramatically in men. Men also gain prolactin, the hormone associated with lactation, as well as cortisol, the stress hormone that spikes in mothers after childbirth and helps them pay attention to the baby’s needs.
