Ming from Agents of Speech explains how to give commands to autistic children: say it once, state the consequence, then physically guide them from behind to complete the action. Follow with immediate praise like "Good, nice listening."
First tip is not to repeat your commands over and over again. What if you say it once and he still doesn't do it? Do you just shut up? Of course you don't. What you do is, hey, open the door. He doesn't do it. You tell him the consequence. You say you didn't tell, you didn't listen to me, you didn't do it. Let me try again. Open the door. You run up to the kid, take their hand and open it for them. Behind this. Do not take a child from the front. Go behind. Because whenever someone's in front of you and they're trying to grab you like that, anyone would have to guard up, right? Think about in their perspective. They're like, dude, what's going on? No, I'm running away, right? So go behind them, take their hand from behind and teach them how to do it. And when you do, the action is. Good, boy. Nice listening. Just think about how easy it would be for the child to follow your command every time you say it. They have no choice but to do it because you're going to get them to do it anyways.
