I just weighed LO tonight, after I changed his diaper, and he weighed 9 lbs 12.5 oz. At his pediatrician appointment 2 weeks ago he was 9 lbs 7 oz. Kellymom says they should gain 5-7 oz a week, so is it concerning that he has only gained 5 oz in two weeks? He has a ton of wet and poopy diapers. I'm not sure if I should call the pediatrician or if that's normal for breastfed babies.
