I have quite a bit of experience dressing a girl but am still learning how to dress a boy. I am taking advantage of the fact that he can't tell me yet what he does and doesn't like, unlike his 3 year old sister who has a mind of her own.
I have discovered that onesies and pants are my go to outfits. Easy and cute. Here he is sporting a cotton white onesie (I love the gerber onesies, you can find them at any target), H&M pants with ribbing to support his growing belly (similar ones can be found here) and robeez shoes. Double chin courtesy of drinking plenty of milk.
p.s. I love the detail on the pants. The little buttons and teddy bears are adorable.
