My daughter is 5 years older than my son and was sitting at the table yesterday doing a "big girl" project. From the other room I hear her ask him, "You wanna help?" Of course he did! She then told him he couldn't.
I told her not to ask him if he wanted to help and then tell him he couldn't. That wasn't very nice. Next thing I know I hear her telling him, "You can help by being quiet." Hmmm.....last I checked that isn't very nice either!
Funny thing is, she thinks her brother talks a lot when she herself talks a lot! :-)
