Wow!
Got it as a gift for my bf and our daughter (Batdad, Batgirl). It was so cute and the size fit both of them perfectly. My bf is about 190 and 6'2 and a size L fit him perfect. My baby is slightly taller than average so a size 3-6 for her at 3 months, so I would encourage a size bigger for your little one!
