Daughter, 10, has extreme tantrums

I have read about people with various allergies or food sensitivities that can cause them to act erratically, much as you describe. You should look for patterns and triggers and have her thoroughly evaluated by her pediatrician. An outside professional can look at the totality of her behavior and help all of you respond consistently, with clear boundaries and consequences.

If she doesn't do this at school, then you have to re-evaluate your home life. She should not only to stop doing this, but think about her behavior: How does her body feel just before she erupts? Does she feel a rushing in her ears? Does her face feel hot? She could train herself to try to recognize these sensations and breathe deeply, get a drink of water or juice, or go to a favorite place in the house while the storm passes.
