My daughter, Emily, is 18 months old. She has 21 hydroxylase deficieny cah and she is a salt-waster. I can't offer you much but I can tell you she has achieved her milestones on time or sometimes even early. IT is very hard to tell if she will have any problems later on, right now she seems quite bright. I can tell she might have problems sitting still to learn anything in a structured manner, since she is very active and busy. She doesn't talk much yet but seems to understand a lot. I hope this helps a little.
