Answer :

Parents should not argue in front of their kids. As much as possible keep the kids out of ear shot when arguing with another adult. This is to make sure that kids that fighting is not good and that when problems arise, they should be discussed and dealt accordingly.

Well, I think it's not all about parents. What if the children learnt it from school, like you know came across 2 seniors or 2 teachers fighting? They'd pick up words from there too. So, I think the parents should sit down with their kids and teach them that when elders are talking they should go play in room or something. And elders themselves, should know how to handle a situation and that screaming and yelling and shouting isn't gonna help. They should remind themselves that there are kids in the house and they should keep it low. If a loud discussion it supposed to happen, have the children out of the house or have the adults move to some place out like a park or something.. This is all I understood...I have a felling it's wrong...But just message me if you need anything else. Hope it helped!! :)
