Just because your new husband isn't your child's biological father doesn't mean he's going to slack off when it comes to parenting. Maybe it's cause you gotta be a mensch to take on the role of stepdaddy, but a new study has shown that married "social fathers" do just as good of a job at parenting as biological fathers. In fact, the remarried mothers reported more
cooperation from their men than the mothers who were still with their baby daddies. The guy who scientists say does the least? Your live-in boyfriend. Sure, he helps out with the rent, but make sure he doesn't get you pregnant.
