My son (EC) asked me this question after having me first sit down on the couch and then grabbing a small wooden chair for himself to sit on directly across from me. This happened when Ethan was four years old and his sister, Leia, was only several months old. It was early in the morning and EC had a rather serious look upon his face and tone in his voice. He went on to inform me that Leia had been smoking (“ciga-rats”, as he liked to call them back then) in her room and we had to do something about it before it got any worse.
