It is really a judgement call for you T.. I had one who was so shy and anxious around strangers that it was effecting her life. She could not do anything, and there were other elelments of OCD and anxiety. She had been like that since she was a baby. When she could not manage to get on the bus to go to Kindergarten, we saw a child psychiatrist who treated her. It was night and day, and I am convinced that this was completly chemical. I so wish I had helped her sooner. She, like yours, was a very pretty child, with huge blue eyes and everyone talked to her, once, in the grocery store, a man smiled at ther and told her that she was a cuite, as we walked in, and she was still crying when we got to frozen foods, she had just stopped as we got to the check out, when that same man talked to her again, saying "was I really that bad?" and it started all over again. I wanted to buy her a button to wear that said, " Yes, I am afraid of you, so please don't talk to me!"
When the child is misserable, and when it truly effects their lives, then it is time to seek help. Only you can make that call.
