You're not alone. I have a 3-year-old daughter who acts the same way. She also embarrasses me in public places and I wish I could just disappear. She does things purposely to trigger me off if I'm not paying any attention to her whatsoever. She throws things, breaks things, screams at the top of her lungs, etc. I too sometimes give into the adult temper tantrum and wind up yelling at her. I am so stressed out at the moment, I don't know what to do. I feel as if I'm losing my mind. So don't feel bad. I thought I was the only one.
