Anatomy: 101

Mia has never inquired much about Sam's privates, but the other day I was changing him and she asked why he had "that" and she didn't.  I said "that" is a penis and boys have them and girls do not.  She agreed and said that her privates look "plain" because she likes to eat "plain" english muffins and "plain" toast for breakfast.  Gotta love how a 3 year old brain works.
