While helping Lia in the bathroom this weekend.
Lia: Mommy, why do boys pee standing up.
Mommy: You mean pee-pee?
Lia: Yeah, pee-pee.
Mommy: Because they have a penis.
Lia: Why do girls sit down?
Mommy: Because of the positioning of their urinary tract opening?
Lia, informatively: Girls have a China.
Mommy: You mean, a vagina.
Lia: Yes, a vagina. That’s so cute. (She thinks for a moment). I want to call it an Indian.
