America's parents are going through a year of tough choices, and it isn't getting any easier. With the school year starting, many have to choose between their jobs and staying home to take care of their kids. More often than not, this burden falls on mothers.

And of those not working, women are nearly three times more likely than men to remain home for the kids.
