Children Throwing Tantrums

I've found that praising them when they do good does wonders. I really had to pay attention & look for opportunities to do this. For examlpe, if we went in the store & he was good usually no-one would say anything. But then I started telling him he was so patient when we waited in line or if he didn't ask for anything I would tell him it was so great of him that he didn't ask for anyhting while we were in there.If he played really well w/ no fight ing I would go into the room & tell him he played so well today getting along w/ his sister & sharing. The look on his face was priceless. I really have to keep my eyes open to find something to to praise about without going overboard.... I just remember growing up the only time we were spoken to was when we did somthing wrong. All I heard was : WHAT ARE YOU DOING!!, GET IN HERE!!, STOP THAT!!, WHAT'S WRONG WITH YOU!!!etc. etc. ... All I'm saying is if we praise more, some of the negative behavior might ease up. Just a sugestion.
