How do you explain to your almost pre school kid (4 yrs old going 5) what "discipline" & why we, as a parent, need to discipline them?

Hi! Maybe not the word discipline as I believed even adults are having a hard time to understand the word "discipline" and the rest that comes with it. Perhaps you can teach your child how they wanted to be treated. In relation to respect. For example you can start it from teaching him/her how to "Wait". Let's say your child wants to interrupt you from speaking. Instead of saying no, tell your child you will set a timer and if the timer rings. He/She can start talking and you will have your full attention to him/her. In that way you are teaching your child sense of respect by showing him/her that you respect time, promises and you keep your words. The main key is consistency. You can give it a try! :) Wish you luck!
