G.Y.
I raised five I understand. I would just take away their action figures or any toy that causes a problem. Now what I have found when I babysit for others, is that when a mother yells so do the children. I always think you only yell when they are in danger. I try and use reason with the children. I get down to their level and look them in the eye. I talk normal to them or even whisper so they have to strain to hear me. I also found the more you praise for good behavior the more you will get. Sometimes they are acting out for attention. They really don't care if it is good or bad attention. I have found that the time that would be spent watching tv is better spent interacting with the children. You can do board games, read to them, crafts, etc. My children grew up not watching tv. I found my household was a whole lot more pleasant to be in then most. I also encouraged the love for reading to them. I don't know if this will help, I hope it does.
