S.H.
well, i say his weight if fine, but it depends on how tall he is too. my son weighs 34lbs and i cant remember how tall he is, but she said hes about and inch taller than most kids his age. Theres nothing to worry about. tell the MIL to calm down. as long as hes eating good and is active theres nothing to worry about. start worryn when he stops eating and becomes lethargic and loosing weight.
