I’m baffled.  My son has a bone age roughly once a year.  Last year, when he was 5 years 10 months, his bone age came back reading between 5-6 years...perfect for his age.  This year, when he was 7 years, 1 month his bone age came back 4 years 6 months!  Can he really be shrinking?  My pedi isn’t concerned, but I sure am!  What do you think it means?  Has anyone ever had this happen?  I’m waiting for the endo to call!
