Everyone, thanks so much for all of your replies. I will do some more research on these ideas. I don't know what we would do without the Internet!

I have not gotten much information about the bone age yet as we just got that news 3 weeks ago. The Endocrinologist is doing many tests. I've sensed that she hasn't been growing right for a while. I had to push for this to be done but wasn't expecting it to be so delayed. I wish I had done it a year ago, but that's all in hindsight! I am feeling overwhelmed with trying to investigate so many issues at once. At least DD5 is in a happy place for now. And she's my challenging child! smile
