You ultimately teach people how to treat you. And while this is 100% true, it’s not always easy to figure out how to teach them… especially the ones that don’t listen.
When someone yells at you, do you do what they want in order to make the yelling stop, or do you wait until they ask nicely? If you wait for them to ask nicely, you are teaching them what works.
The same principal applies to your kids. If your child is having a temper tantrum and you give him what he wants – he learns it works and he does it again.
How you respond to their behaviour is how you teach them what works.
