I thought tantrums started at least at age 3?

Elise wants everything her way! or the highway! Now she trows her self back when mad sometimes hurting her head. Everything is crying and being mad! :/

    Tristen started that at about 7-8 months...I was shocked that it started so early. Every time he was not allowed to do what he wanted, it was a complete meltdown. Full on throwing himself back and rolling on the floor, kicking and screaming.
