Mia, almost four, abides no fools. As evidence, I present the following:
Mia has a doll that she received as a gift the Christmas before Owen was born. His name is Baby Herman. Baby Herman spends months neglected on the floor of her closet, and then experiences a surge of popularity and is treated like a real human child for several days before he is again abandoned. Last week was a Baby Herman week. He ate with us, slept with Mia, was dressed and undressed and bathed and napped and patted and so on for several days. One night after dinner, Mia was walking around the kitchen, holding him by his outstretched arms, and "teaching Baby Herman to walk." Since Baby Herman was naked, I warned Mia that she had better be careful that he didn't tinkle on the floor. "Mommy," she said, rolling her eyes and smirking, "he isn't real."
Two days ago while tucking Mia into bed, she requested that we talk about lions. I covered the basics, live in Africa, live in groups called prides, hunt animals to eat, sleep a lot, etc. And then I said "Hey Mia, do you know how to tell the difference between a boy lion and a girl lion." And she said "Yes!" And I said, "Well, how do you tell?" And she said, "A boy lion has a penis."
Not quite what I was going for, but I couldn't argue the point.
