Oh, didn't see the book recommendation request. The first one I read was The Highly Sensitive Child by Elaine Aron. Very good layman's view explanation of all sorts of things (e.g., clothing and food taste/textures sensitivities, avoiding birthday parties, staying out of the fray on the playground, etc.). Others are The Out of Sync Child and The Out of Sync Child Has Fun (for activities to do togethter). Dont' have them in front of me so can't give you the author's name.
