My DS3 has the most amazing temper tantrums, truly amazing! For a while I tried time-out, ignoring etc to no avail. Then one day for some reason it struck me as funny. He threw himself down, started stomping his feet and screaming. I laid down on the floor right next to him and started doing the same thing. Asked him if I was doing it right? Did I need to yell louder? He stopped mid scream, jumped up to his feet like I'd grown an extra head, then curled up next to me, patted my arm and told me it was ok. Since that day, his tantrums have been very small and very infrequent. Still don't know why it worked, but it did!
