If your daughter is on too much medicine it can slow growth (both height and weight). This happened to my daughter. We adjusted WHEN we give her the medicine not the amount of medicine we give her. She is growing much better now and her levels are excellent. We give her meds at 3am, 7am, 12noon, and 5pm. She is on a total of 3.75mg Cortef a day. She is 2years 2months old and weighs about 24 pounds and is 32 inches long. (Too little medicine and growth can be too fast at first but then they stop growing too soon and are short.) I hope all goes well for you. Julia
