I'm so glad your little one is making progress. ABA has research to back it up, but it's a major undertaking - very intensive, as you know.
I don't have any experience with ABA providers, but I'm sorry you're having problems with over billing. Maybe you should look into another therapist if you're having problems. I don't know if you have the option, but it's a thought.
The board is going to go read-only tonight, but I hope you stick around for the new boards on Tuesday.
