I am no expert on things like this but it sounds to be that her skull is growing faster than it should be. When it does it doesnt leave enough room for her brain as it grows. The only reason why I am guessing this is because this sort of thing happened to my husband when he was that age. His mother keept trying to tell dr.'s but none of them would listen to her untill it got to the point that he had a bone buldging out of his forehead. They then had to go in and remove that part of the bone and make that his soft spot. The problem with him is that it took to long for the dr's to relize it and when his brain had grown so much it didnt have the room it needed. He was to the point that he was having bruising on the brain. Any way I dont mean to scare you with his story. I am glad that you noticed it when you did before it got to late. Hopefully all she needs and surgery to correct it and not have as many problems as my husband 30 some years ago. I hope all goes well!! Keep us informed if you dont mind.
