Disciplining Those Mentally Challenged

Have you sought out someone with a genuine ministry of healing in the mental area ?

I've worked with some autistic children in my Medical career.
I have a 3 year old nephew who is. Advanced in many areas since he was 2. B/c the spectrum it is then each kid/person with the same diagnosis level doesn't act the same.
You're biased in this is your own child. My nephew is family but I can still see him from both sides.
The last church I went to had very few who had experience with autistic children.
IMO, like a change in mindset when becoming a Christian, it isn't some light bulb thing. I've learned to see other people differently than I used to and with autistic people the same way.
Almost all of them need balance and a schedule. I've seen that most live well with them but love them.
If he doesn't have a nap at roughly the same time period the rest of the day is off for him. He still doesn't know how to talk with what he wants and wants to say.
There are many options but most importantly, IMO, I think God handles children and others with mental deficits differently than the rest of us.
I know they know God on some level but somewhere the ability to express it is lost and/or jumbled.
