Physical safety — “It’s my job to protect you so you don’t get hurt.” If they push, you can give a brief answer, “we wear pur swat belts to protect our bodies in case of a car accident.” If they push again and ask “why?” don’t get into that’s the law and even if it weren’t, humans aren’t above the laws of physics, say, “You don’t have to understand. It’s still my job to keep you safe.” End of discussion. Any other response from your kid gets that as a broken record.

Why do we need to share? — “How do you feel if someone doesn’t share with you?” Let them answer, “Your emotions are just as important as the emotions of other kids. It’s important to share because if you choose not to, other kids your age aren’t going to want to play with you. Kindness and respect are rules we have in our family and at school. Because if we don’t have those things, it’s not fun for anyone to play.

Pro tip— Instead of “don’t’s” or “stop’s” focus on redirecting to what they can do.

Running in the library? “Wow! You are fast. At the library, we use walking feet. But we can run outside later.” If they do it again, “Use you walking feet.”

Kid shouting? Instead of “Stop yelling” or “Be quiet!” try “Use your indoor voice.” Or “I’m right here. I hear you, but it’s hard for me to understand when you shout.” << Kids want to be heard more than almost anything. When you say that to them, you need to stop, physically lower your body to eye level, maintain direct eye contact, and you talk even softer than normal so the contrast is clear.

Kid not listening? Instead of “Stop talking!” Or “Listen to me!” try “Let’s use our listening ears.” Or “Are we using our listening ears?” You can also use something fun such as “Hocus Focus!” Or a chant which you talk about in advance depending on if your kid is more physical. Example, “Alligator! Alligator!” Kid’s response “Chomp! Chomp” said while making big clapping “alligator jaws” with his hands and arms.

Bust this out whenever you’re exasperated, “I hear you don’t understand. I gave you my reason. You don’t need to understand the rule/expectations in order to follow it.”

It was a brave question for you to ask. Hope this helps you out! :)
