'The time fathers devote to child care every week has tripled over the past 50 years in the United States. The increase in fathers’ involvement in child rearing is even steeper in countries that have expanded paid paternity leave or created incentives for fathers to take leave, such as Germany, Spain, Sweden and Iceland.

In terms of brain function, for instance, gay male fathers who are primary caregivers show stronger connections between parenting brain regions when viewing their infants, compared with secondary male caregivers.'
