2 year old missing hair

Shawna

So yesterday my daughter came home from the babysitter and was missing a patch of hair on her right side temple area. She has a full head of long curly hair that goes half way down her back and it looks like it's been shaved or pulled out. It is very strange. The babysitter said nothing happend and that she does pull on her hair, which I have seen her do at home when taking her hair down. Has anyone else experienced this. I just hope it isnt something else medically.
