Posts saying my child has asd and doesn't do this/get away with this, awesome, have a medal. Maybe if the mum here was aware her child might have something deeper going on, she would be able to find which techniques to best employ to support her child so hers behaved better too? None of you were using now and next or 'pandering' to your children taking as much as they need from home in order to reduce their anxiety and resulting behaviours before you were actually aware there was something more going on were you.
I have two asd children who go to bed and stay there and one who doesn't. They are separate people with different difficulties, needs and anxieties, not one homogeneous asd being who all react the same way to whatever technique/boundary we try
