One and one can mean more than double the trouble when it comes to having a second child, an ongoing study at the University of Michigan shows.
"This affects a woman's career path," she says. "No matter how egalitarian the couple is, a second child usually means that the husband and wife fall back into the more stereotypical roles."
"It's a way I could thank them for being a part of the study," says the 30-year-old single, post-doctoral student. "The project has changed my idea about having children, too. I go between either wanting to have two right away or none at all."
