“I love being a father,” the actor, who turns 34 on Tuesday, said. “It’s wonderful. It’s changed my life. It all sounds like platitudes and clichés, and that’s because they’re the truth.”

He’s even proving his babysitting skills with Violet, his 8-month-old daughter with wife Jennifer Garner, 33. Just a few days ago, he said, Garner left him in charge of the baby – but first explained how to feed her.

“(Jennifer said,) ‘You take the peaches in the thing and you stir that up and you put that in with a little oatmeal and then put that in with a little bit of the crushed pears.’ Then she looked at me and said, ‘In all seriousness, is this too complicated?’ That’s my wife.”
