Ohh I have a very big problem with this too. I have a three year old daughter she is always doing this, she also screams anytime I take her to town she is very greedy and people stop me on the street and ask me why my child screams like this. I just ignore them in embarassment. 

Also she ALWAYS wants to watch the TV all to herself and when I don't allow it she will scream for hours and hours so loud she never gives in. She also punches me and shouts at me. She even calls me 'fat belly' to annoy me. She also like to wipe her nose in my clothes to annoy me also. She is a little bully. No matter what I do, even when I beat her hard, she laughs at me.

The way I disipline her is take her clothes off and threaten her that I will give her a bath and throw lots of water at her. Then she stops right away.

If you are complaining about your boys,then you need to see my girl ! She is just 2yrs but she is like pepper to the eye . A one man army,chase her away from somewhere,the next seconds she is back to that same spot. She is really a TOMBOY !

Awwww! Too cute!!
