Its not uncommon to yell at your kids to correct and control their bad behaviours. Children aren’t bad, but sometimes their actions are. If parents don’t tell them whats wrong, and unacceptable..then they wont learn the difference between good, and bad. Yelling, sometimes seem like the only way they hear you. Because like most kids, and even people are too busy thinking about themselves, they lose their mind about others.
So by all means.. yell at them, when they need to hear it.
