It's so important to keep on this. My son's growth was out of control for a period of approximately one year. My endo would never share numbers with me regarding labs. He would always say "everything is within normal ranges". Being the trusting person I am I believed him. My son's bone age advanced 5 years within a one year period. We have since changed doctors, but I just wanted to also stress the importance of knowing your childs #'s and not being afraid to stand up for you child. If you don't, who will?
