Many fathers say the biggest issue they face is balancing work and parenting.

More than 15% of dads who work 35 to 40 hours a week wish they could work less. And the average father in a couple spends only 2.3 hours a day with his kids (compared to 5.8 hours for mothers). Dads also say they worry about how to discipline children, and about the best ways to show affection. For many it's hard work getting used to talking about parenting with their partner and other dads.
