I think a chiropractor is a good idea. I would like to suggest another. I work with magnetic products, which is the earth's natural energy. I know of a lot of grown ups that the products have helped with migraines. I don't see why it wouldn't work for a child. I also know of many children using the products for other things or just to stay healthy. If you want more information, or even to try something, get in touch with me.
Good luck.
