EXCLUSIVE PHOTOS - Josh Duhamel Is On Daddy Duty With Son Axl

Ahhh little Axl is so cute!

On Tuesday afternoon Josh Duhamel ran errands in Los Angeles with his three-month-old son, and after a stop at the gas station, the boys were back on the road and headed home.

Josh recently revealed that this will be a pretty mellow Christmas for the family, and at the March of Dimes Celebration of Babies luncheon in Beverly Hills earlier this week, he told E! News, "I'm loving it. I look forward to many more. I can't wait for him to tear through gifts. It won't be this year."

"Our Christmas plans are pretty simple this year," he added. "I like it that way. We're home, just family around here. My mother's out here right now. My sister's coming out next week. Other than that we're just going to stick around here."

Duhamel also chatted about why he's so eager to support March of Dimes, which helps parents struggling with problems affecting pregnancy and premature babies. "I don't really feel proud of the fact that I'm admitting this, but it isn't until you have a child that you really can understand what some parents must go through who aren't fortunate enough to be blessed with a completely healthy child," the new dad said. "We luckily were and it's a chance for me to help in some way, some small way, those who are struggling to raise a child with special needs."
