Babies grow really fast: Josh Duhamel

Los Angeles: Actor Josh Duhamel says his baby boy is not small anymore. The 41-year-old actor said he becomes emotional when he thinks about how fast 13-month-old Axl is growing up, reportedly.

"He's already swimming around in the pool, and I was like, 'What the hell happened to my baby?' He's walking all over the place, talking. He's a toddler now!

"It happens quick. Next thing you know, they're going off to college. So that's one thing I've really taken to heart, trying to be there as much as I can," he said.

The 'You're Not You' star admits that although he is proud the little one is hitting milestones, Axl has already worked out how to test his patience.

"They get to a certain age and they start to test you a little bit. He likes sticking his fingers in holes. So he'll stick his finger up my nose. I'll be like 'no you don't do that.' Then he'll stick it up his nose. And he thinks it's funny."
