My ten year old dd was notorious for doing this type of thing at Wal-Mart or Target. The first time it happened she was right at 2 years old and I took her to Target to let her pick out her own panties since she was starting to use the potty. Well, we passed the toys and she wigged cuz I wouldn't get her something and slapped me, I was appalled b/c it was very out of character. We just had to leave our cart and go home. I was mortified because I guess I'd never given any attention to other peoles kids and had never seen anything like this. I didn't realize it was going to progressively get worse for me, LOL. Once in Wal-Mart dd (3) was pissed at me about having her ride in the cart (she was bad about running away and Foster was an infant) and she was kicking and screaming saying "somebody save me from this woman", the lady at the jewelry counter asked if she was my child. I said to her "Really, who would take a child that was going to draw so much attention and assured her that I was her mother. This too shall pass. DD never draws attention to herself in public anymore.
