My son was always in the 90th percentile or above for height since he was born. Since his diagnosis (May 2008) he has hardly grown at all and is now only in the 30-40th percentile for height. His weight has increased and he seems to be growing fine in that area--just not height. Is there anything I should be concerned about? He eats a well-balanced diet so don't think it's related to that. We had his thyroid checked in the past several months and the results came back fine. I guess at first when I noticed it I kind of chalked it up to being newly diagnosed and his body just getting re-adjusted, but now I'm not so sure. He has an endo appt in a couple weeks so we'll ask them again, but so far they have been unconcerned. Has anyone else experienced this? Any thoughts? He was 36.5 inches at his 2 year visit and now he is 37.5 inches at 3 years.
