You don't have to teach a toddler how to throw a fit. You don't have to teach her how to scream at you.
I never taught my daughter that she should throw her food or her dishes on the floor. Nor have I taught her to ignore my requests.
However, I apparently don't have to teach her how to clean up after herself either. A couple days ago she spilled some milk out of her sippy. When she noticed the dribble on the floor, she ran to the kitchen, pulled a towel out of the towel drawer and came back to wipe it up.
I'm not sure if this is really my kid after all.
