You're a good mom. You're trying to meet your daughter's needs, rather than trying to beat the autism out of her as so many parents do.

I see you're following me. That's good, to hear from actual autistic people. Your daughter is frustrated because she can't communicate her needs effectively. If you read other autistic voices you'll get an idea of what she may be going thru. Please check out Actually Autistic, an autistic blog and newsletter, it's here on Medium.

I agree with others, ABA is very harmful. There are other ways she can learn to communicate -- picture boards, etc, and when she can do this she won't have to scream so much. I'll post the link in an edit to this message.

Thank you for loving and caring for your daughter.
