Good luck with your eval. They make me nervous too. Luke has one on Wednesday. The nice thing about having an eval with an autism expert is that they get your kid. They know what to expect and how to interact. So even if you can't get more specialized help than your public school offers right away, they may have some hot tips for you. Also a diagnosis means JR may qualify for more help from the local district. Anyway, I'll be keeping you in my thoughts.
Bless your heart.
