Lucy and I just played "princesses." I have no idea where she learned this, but she put on her dress-up, a crown, and some high-heels, and she turned into a fancy hair-flipping hip-swaying gal. Throughout my lesson, I learned the following:
"Princesses need to eat food, because they have babies in their tummies."
"Princesses have to be respectful to their kings who married them."
"You have to stay in the lines (while coloring), or you won't be a princess."
"Princesses brush their teeth in the morning, the afternoon, and the summer."
