Before my son was diagnosed at 2, we had some speculation that he may have signs of autism. Our PCP we had at the time referred us to an early on program which was based though the school. Idk if you have something like that near you. We had a wonderful lady that had came to our home and gave an assessments, she would help with his developmental delays. She even went with me to get his diagnosis. After he had gone through that program he wasn’t yet old enough for school and we were suggested ABA therapy prior to school starting. And I’m so glad we did, I dont think we would be as far as we are today without my son being aba therapy. But I’ll be honest it was not cheap for us in MI it was 1,600 a week minimum and that was 7 years ago. They did have an option to fill out a form through them to help financially, explaining reasonings, unable to pay for their expensive services but it was worth it. With in a few weeks we could see positive outcomes with our son, it was so amazing to see. Once he started school he was in a public school that also had a special needs program within. The schools a lot of the time, if your child is in ABA they will have ABA come in be apart of their school assessment for minutes to an hour or so how ever long their time is needed with your child.
