I don't think yelling at adults or a child gets you anywhere. That is not to say that I have not done it to my child, nephews or nieces!! But I would definitely say talking can deal with most of the problems, most of the time the severity of your voice can change a person’s ways without the deafening shout.

Once my kids hit their teens, this seemed like it turned into a daily activity.

I could even write it into my daytimer.....

6:00pm Dinner.
6:15 Yell at oldest son
6:45 Yell at daughter
7:15 Yell at oldest son again.
7:45 Yell at oldest son again
8:00 Yell at youngest son so he doesn't feel left out.
