Jeffrey Goldberg picked up his infant son, Isaac, caught his little arm in his sleeve and proceeded to bend it backward slightly. Oops. Isaac screamed, of course, but also bounced back in a hurry. "I still feel bad about that, but he was fine," says Goldberg, 30, of Framingham, Mass. "Babies are pretty tough little things – they're amazingly resilient."

At least Goldberg didn't drop Isaac, which is something he's feared doing since his baby boy was born in March. Yet it's a fear he shares with many other new dads, not to mention concerns about how to dress, soothe, support financially, feed and care for a new baby.

New moms haven't entirely cornered the market on newborn fears. Dads are worrywarts, too. And though many fears – such as, "Is the baby still breathing?" – are shared by Mom and Dad, new fathers have a set of concerns about their new babies all their own.

"Society has changed in a way that encourages fathers to take an active role [in] all aspects of parenting," says Dennis DeWitt, a father of two and a health educator who teaches "Toolkits for Dads-to-be," a class offered at Kaiser Permanente in Portland, Ore.
