Hi Israel, Mrs. Israel & Chelsey,
I found information on a web site. It may be something you want to discuss with Chelsey's doctor.

I was very happy to read Chelsey is improving. I understand how helpless you can feel not knowing how to help her. But keep on praying for her (I will too!) and give her LOTS of encouragement, happy thoughts & LOVE her more than you thought you can!
Please keep posting her progress.
