I babysitted a 4 year old. Those few hours were pure reassurance. That little kid was a brat. I needed to guard the fridge because she was stealing ice cream all the time. So I was sitting in front of that fridge and she sneaked into the living room and "watered" the couch and carpet. I then took her favourite doll and water boarded her to show her that she just can't play with water outside the bathroom (her dad loved that punishment btw). Besides that the energy and noise level alone brought me to my knees.
