He's blindly going by his chart produced for the average baby. The baby was not lethargic nor sickly. She is breastfeeding and prefers to do that solely. My BIL was told by the pediatrician that his child may have a problem as they were off the charts. He's 6'7" and the mom is 6'2. The doctor didn't consider that...only what they are hand fed by the AAP.
