jess eats but does not seem to be gaining any weight. he would of course choose ice cream over fruit, but my daughter is very conscious of presenting healthy foods to him. he has a brother 15 months old (not with cah) and has more meat on his bones than jess does. jess's bone age is normal and dr. new does not seem to be concerned about his slim appearance. he just doesn't look healthy to me. he is the same height of all his friends but so much slimmer. i just wondered if cah children tend to have any problems with failure to thrive.
