My 11yr old is the same height as she was when she was 9yrs old. At 9 yrs old she weight 68lbs now weights 61lbs. She adhd and when she went to the dr to change her prescription they noticed her height has not changed in 2 1/2 years and the dr took blood and x rays. And now going to see a specialist. I have no idea what is going on. The doctors almost act like it is a secret and don't want to say anything, any ideas? What is happening to my baby girl?
