I take my role as a caucasian mother raising AA children very seriously. So much cultural information that a AA child might pick up just being in a black family or community generally becomes a purposeful conversation for us. Some are important pieces of history or teaching racial slurs so they know when they are being insulted - a coping skill they definitely need to know. Then there are the hilarious or absurd conversations as the one we had last night.
My Ella is a very curvy girl already and will become more so as she grows and giving her a good self image is utmost on my mind when I look at how quickly she is physically maturing. So conversations such as we had in the car last night are important for us to have. What a huge disservice I would do to my daughter to send her out into the world completely ignorant to her history and culture. Therefore, we had a talk about big butts - yes a very cultural conversation.
Then I launched into the song from Sir Mix-A-Lot that they know from Shrek, "I like big butts and I cannot lie!"
