Believe in your child's ability to learn and FEED it.... Starving it because of a bit of mess or in our case it will be recarpeting and repainting in a few years...... Is still way way cheaper than the cost to his learning if we had taken every thing off him.
You do know how to communicate with your child we have been lied to and told we don't. Sit and watch what ever your child is interested in with them. If he/she jumps and spins at certain things do it too. It will help you understand why he/she is stimming.... Is it stress or is it because he is ultra happy with something he has seen or heard? You will start getting his attention. Learn those terrible crappy Peppa pig songs or what ever else they are keen on. Introduce him/her to YouTube with what ever their interest is. You can do amazing things just showing your interest in him/her. And after time when you see him/you showing interest in you link what he enjoys with other things you want him/her to learn. Watch out for when his/her interests change and adapt them to link what he needs to learn too. Oh and please please read "The Spark" by Kristine Barnett, she got my brain started and reminded me that neurons link together and that even on the other side of the world your best teacher for your child IS YOU and no one else. And you are welcome to message and friend and ask anything. I want all our kids thriving.... The more kids doing well the happier I am and the better the future for ALL ASD people.
