Hi all
My son (now 8 years old) was late to train too, I found big boy pants a real big help, sort of like removing the safety net of training pants. When it clicked with him, it all happened quite quickly. He still has issues cleaning himself after a poo though, I perhaps am too quick to run and help him but again, I know it will all fall into place.
Patience is the greatest gift us parents of ASD children were given!
