There's some great advice on this thread and of course, the expected idiots who have to interject about something they know nothing about.
As someone who works with special needs kids I would emphasize talking with your kid's pediatrician and school about what strategies, counseling, advice etc is available for your family and your child. Make sure that your child has an IEP or 504 plan in place to help in school. When your child is young you are their advocate to help your child be successful.
