Thank you playfelt. You've given me a different direction to look at.

This morning she was trying to get by a child. She started by says "GO" loudly, when the child didn't move she picked up a toy and hit her with it. 2 weeks ago the same little girl pushed a child off the slide because they wouldn't move. I'm concerned that the aggression is more then I can deal with... or maybe should deal with.

I will try your suggestions and see how it goes. My frustration is that it's gone beyond normal 2 year old hitting.

But! No biting! (know on wood) Thank goodness for that.
