I'm not a mom but I do the same thing with my neice. She bats her eyes and everyone gives into her every time. So one night she was having a sleep over at our house and didn't eat her dinner... I was grabbing some ice for her brother, he hit his head and we were going to put some ice on it and saw some cookie dough in the freezer. She tried to take it and I said no. She doesn't try that with me any more.
