2 ½ year-old Fears

Question:

I recently read your book, Positive Discipline: The First Three Years and I cannot tell you how much better I understand my 2 1/2 year old son! I was hoping you could direct me toward some reading material, or even offer a suggestion though. He is a very bright boy, happy at home. However, he is constantly telling us he is “scared” of other kids, and sometimes adults too. It seems to really hold him back socially. We had a psychologist meet with him, but she stated he is just high strung. I somehow think there is more to it… If you could point me in a new direction?

Thank you,

Erin
