Logan is very quickly outgrowing his sleepers (with the feet), so I broke out the BIG BOY pajamas! He doesn't look like a baby anymore; he looks so grown up! These are 12 month pajamas! I went to buy him a few fall outfits, and had no clue what size to buy. I ended up getting two 18 month outfits, since he is already wearing 12 month now! I hope they fit! I guess I will hold off buying anything else until I know what size he will be in the upcoming months.
