You're absolutely right that the parietal lobe does not affect movement. Does she have any problems with her cerebellum?
Hi, Crisana, and welcome!
I'm so sorry for what's going on with your daughter. This must be really scary for you. Unfortunately, I have no answers for you, and your pediatrician and the neurologist will be your best resources. It doesn't sound like a Multiple Sclerosis problem to me...hang in there - Friday is just day after tomorrow!
