We visited the pediatrician today, and he advised putting my son on a vitamin supplement with iron. My son's not anemic; in fact, his iron levels were "excellent"--as in 4 points higher than the baseline. Ped said to give the baby the supplement once a day to keep him from becoming anemic. Do I really need to give my son a supplement? He's doing great; he's gaining well and is healthy. So I really don't know if he needs the supplement.
