I got this for my son for xmas day -- not sure if you have a Children's Place store? But, just to give you an idea.......
As a baby tho i had tons of christmassy outfits for him -- one for almost everyday in December!!! I especially loved fuzzy sleeper type outfits, especially feety ones! Personally i feel they have the next 80 years to dress like "men" -- i wish i dressed him like a baby when he was a baby! Instead of dressing him like a "man" which i did alot! I think a suit should only be for a wedding... or communion maybe...
I wish he was still young enough to dress all cutesy christmassy -- i feel i rushed those days!
