I agree with most other posters. I would not do this "full" evaluation at this time with your child. If all is working at the moment, then right now isn't the time to interrupt her life. Experience has taught me to say no to testing (medical or physiological) that we didn't need.

On the other hand do you think you might want to think about if you want to continue to have a relationship with this doctor. Will you perhaps be wanting his help in a few years? Maybe there might be a compromise, some level of "basic" baseline testing that doesn't seem so intrusive to you.
