Thank you, I will tray again and see if it's work.
Thank you very Much I appreciate.

not true…keep trying and hang in there!! The waiver is to ensure health and safety of "vulnerable" people, those who if their primary caretakers were unable to take care of them would be at real risk of needing "hospital/institution" level of care (unable to manage age appropriate self-care, medications, social skills, communication).
The other waivers have wait list you need to ask specifically for the EPSDT waiver (early periodic screening diagnosis and treatment) it is only for "at-risk" and "disabled children to provide the extra services they need. If you have access to a Children's Hospital or developmental pediatrician they should be able to help you with this as it is solely based on medical necessity in one area of development is significantly below age norms.

Yes, he is in the waiting list. But they said that we can't count on them because he speaks a little. They said that waiver is just for divorced people or the very sever children.

Have you applied for a medicaid "waiver"? EPSDT waivers through medicaid pay for what I mentioned above in every state. You should look up local service providers for intensive in home behavior treatment that take medicaid, they should be able to help you secure the "waiver" you need for your son to access more services (also expands payment for speech, OT, PT, and other things as well).

Yes he is in school "special education" and have Medicaid. But the state where we are living "Illinois" doesn't pay for ABA.
