How can i help my child with her obsessions?

Just wanted to mention one time On the Dr. Phil show I saw these doctors talking about a childs nutrition and how it could affect there personnality and mood swings maybe you could check this out I know nothing about williams syndrome but I'm going to look it up, you know lots of times in life being different can be a plus it makes for more original people, more fun, talk to your family doctor maybe he can help you out and make sure not to give the message to Rosie that she is weird or does not fit in on the contrary make her feel special and always give her positive input I can feel it in my gut Rosie is going to be a winner in life and not a follower I send you all my best!
