Wildsky, I'm not sure how to help, because as parents, we all discipline differently.
Frankly, I would have (and have) paddled my child's bottom for tearing up paper and books. But, that's me, and my parenting style.
I have found that taking away something that is special to them also works. for example, my boys love their legos. If they throw a tantrum, don't clean their room, don't follow directions given to them by us, they lose the legos indefinitely. If they ask for the legos (or any other special item that we've taken) to be returned, they wait even longer to get them back. I make it quite clear that the revoked items will only be returned when I deem necessary.
When we send our children to their rooms, we tell them they are not to touch anything in their room - no toys, books, etc. They are to go straight to their bed and lay down on the bed as if to take a nap. This is usually just for ten minutes, unless we catch them up playing or with toys in their bed, then the time limit starts over.
We have a no tolerance for tantrums here. The individually who throws the tantrum absolutely positively doesn't get their own way - no matter what.
Also, instead of giving attention to bad behaviors, try rewarding the good behaviors.
Biggest key is consistency. Once you find what works, keep with it. You will not stop the tantrums overnight, probably not even within in a week. It could take a month or over a month or longer to break the tantrums.
Be firm - not mean, just firm.
Also, if you don't mind a suggestion, on the occassions your son "sets her off" and causes an argument, I'd send him to his room, too, or take away something special.
My kids do not get TV priveleges, except maybe one time a week. I ignore any whining about it. When they ask to watch TV the answer is
a l w a y s no. Not seldom,
A L W A Y S. I tell them, "you have two options, go outside to play or play quietly in your room." if they whine about that, I choose for them. If the weather's nice, I make them play outside.
They do get that 1 time a week TV privelege, but they have to have kept their rooms clean all week, not given any lip, not thrown a tantrum, and then it's a movie/show of mom or dad's choice, not theirs.
Like I said, we all parent differently, and you may not like anything I said, and that's OK. I'm just trying to share what's worked for us.
