Hi there. Ah, sounds like a lovely little girl. Please know that kids can adapt and do quite well. I would try to socialize outside your home or have people over to your home a little more. That in itself will help her learn to communicate better with people. Don't let your anxiety hold her back! I would try some small outings with her to see how she does. Encourage her. Be friendly to others. Her seeing YOU talking to others gives her the greenlight that this is what we do. Maximize the positives and minimize the negatives. I am glad she is going to mainstream school soon. Will she be in a regular classroom? When does she begin that?
