Actually caught one of her shudder attacks on video!! Dr(neurologist) says theyre harmless and shld go away in a couple years TOPS if not sooner. We thought they cldve been seizures or something but he knew them right away which from what ive read is pretty rare for most peoples dr to know about!:) We are in MN and he is a neurologist at the Duluth Clinic. I hope this helps yo ease another worried mother like i was at first!:)
