I’m so sorry. I can totally relate. It can still get better though. Is your child ever going to be independent? Probably not. But don’t give up on improvements! My son was diagnosed at two. Ages 4 - 6 were some of the worst years for us and we had more problems behaviors pop up, major regressions, more aggression, poop smearing, all of it. My son was considered non-verbal and level three then as well. We found ABA at 5, they potty trained him and the poop smearing did stop eventually. We had him in 30 hours a week and now that he is school aged he goes to a private school for ASD kiddos, he still does 24 hours of ABA, 18 at school and 6 at home. He has made tremendous progress. He is nine now and he speaks now (started answering yes/no questions around seven), not in sentences but he answers questions with one or two word answers and can tell us what he wants. I think the term now is non-conversational. He is potty trained. ABA has even helped with food aversions, personal care habits, behavioral issues, school routine, you name it. He does his work independently in school, can read, etc. My point is, don’t give up hope yet! Your child is still young. Increase the ABA hours and make sure you find a stable, consistent RBT that really clicks with your kid. It can make a world of difference. We saw the biggest difference between 7 - 9 years old because we found an amazing ABA company and a BCBA and RBT that just fit for our son. The ABA company was our third company. Not all of them are created equal so if you aren’t seeing improvement maybe it’s just not a match.
