great thread everyone!
just my two cents...When your child throws a tantrum always try to be as calm as possible, speak in a normal voice, don't feel like you have to stop the behavior a.s.a.p. Be firm in your stance on the issue, don't ever give in if you are "right" or the child will learn to manipulate you.
Ignore bad behavior and reward good behavior.
when your child must be disciplined just remain calm and Consistent, they are smart, they'll learn about consequences quickly.
Choose your battles wisely!
I guess that was more than $0.02, oops
