Ming from Agents of Speech explains how to teach children with developmental delays: praise good behavior constantly with varied language, and handle bad behavior by ignoring it or calmly stopping it without scolding. Taking good behavior for granted damages your relationship with the child.
Build good relationship. Make them comply. How to make sure that the behavior is good? Only start with two things, which is one behavior. Praise the good things that your child does, no matter what, in a good way. Think about 10 Ways to say the same thing. It could be. Ah, nice sitting. That's awesome. Sitting. Oh, I really like the way you're sitting. Wow, you're sitting so nicely for five minutes already. Okay, here, I give you another toy to play since you didn't play with it. If you do this over and over again, kids are gonna love you. Because when you see something that's correct, you praise like crazy. And then when they do something wrong, you don't scold and you just ignore it. And you use your hands and stop them. And then after you stop, you say, that's right. That's a nice stopping. Thank you.
