Just a thought here. I think the chiropractor is a good idea. If an illness could be the reason for the problem The little boy may not feel as bad about it and a few treatments at a chrioprator won't hurt, may help and even cure him physically and emotionally. It is not his fault. He is only 4 years old. I hope this little one makes it through unscared. NO TUFF LOVE FOR THIS DELICATE PROBLEM. He needs a better doctor.
