I have 3 - ages 14, 12, and 5. My youngest is far worse than my older two ever thought about being.
She did not go through the terrible 2's, but I promise you she is more than making up for it with her terrible 5's! In fact, we just came home from school yesterday with her laying in the back seat of the car, kicking her feet and HOWLING at the top of her lungs because I told her she couldn't go to her Granny's house.
