It was like life during wartime. I would come home from a full day of work and both of them would be screaming their lungs out. But then around three months it changed. They started to smile.

NEW YORK (AP) — Fatherhood in America has changed over the past few decades. Dads today are more involved in every aspect of child care, from diaper-changing to helping with homework. Nobody questions paternity leave — even Major League Baseball players take it — and stay-at-home fathers are no longer unusual. And while there are more single moms than ever, kids raised by two parents have a big advantage over kids from single-parent homes: They are less likely to be poor.

Despite the changes, when you ask today's dads what fatherhood means to them, they cite some pretty old-school, universal themes. A team from The Associated Press recently photographed 10 sets of fathers with their children, and when they were asked about being dads, they mentioned responsibility, hard work, joy and pride.

When you?re younger, you?re so busy with everything, you don?t have time to appreciate it.? (AP Photo/Kathy Willens) (Kathy Willens/AP)
