My baby cousin is 6 months old and extremely round for his age. At his last check up I think he was almost 18 pounds. He has hand-me-downs from my son (2yrs).... I was visiting with my aunt the other day and noticed he was wearing my sons old pants.... they were 12 month pants and it looked like he couldnt even breath. She went to change his diaper and it was a struggle to get the pants pulled up so she pulled out another pair of pants (again my sons so I knew the size), they were 12-18 month size and they fit him fine. His shirt was pulled up and he just looked plain fat, not cute baby fat. Is it bad that I think my own blood is just really fat. His smile is amazing but that is all this kid has right now.
