Tantrums....

So we have been going through some interesting moods with the girls and I am not sure how to handle it anymore. It started with Samantha and she is gets totally out of control. She gets so upset over the smallest things, ie: she didn't get chocolate milk, her coat feels "funny", etc. She goes from completely happy to completely insane in about 2 seconds. She is screaming, stomping her feet and hitting things. She yells at her siblings, make disrespectful noises at us and just generally grumps around. She NEVER gets what she wants when she does this. Infact, she typically loses something. Most of the time she is sent to her room until she calms down. There have even been times I have had to send her back to her room several times. We have talked to her about why she is doing this. You can ask her while she is having a fit and she will tell you that the only thing she gets is a time out when she has fits. I just don't get it. Now Paige is starting it and my only thought is what the hell am I supposed to do with both of them doing this????

I know that tantrums are part of life with young kids, but I really thought they would be getting better at this age, not worse. I ask them both why they have these fits, and they both tell me "I don't know". When I ask them if they do this at school when they don't get their way and they always tell me "no". So why do they do it at home??? Both of them can be the best kids in the world, but when they are doing this, I just don't even want to be around them.

This morning Samantha woke up in a mood, and was yelling at Paige before she even came downstairs. And when I say she was yelling at Paige...it was more like screaming at her, starting with the first word that came out of her mouth. It was so bad that when she finally came down to the table for breakfast, I had to send her back to her room. Then when she got off the bus this afternoon she was fine...until she got into the house. She was the 2nd person in the house, and I was the last. She was already yelling at everyone when I got in the house. I am so frustrated with this.
