Party Plans

We're having a birthday party in a couple of weeks. And when I asked our almost five year old son what kind of cake he wanted, he was pretty specific. Chocolate cake (the best flavor!) with pink frosting. Chocolate cake no problem. Pink frosting? Hmmm... I'm trying to remain open-minded, gender-neutral, but with a dozen other kids invited, if I go ahead with the pink frosting am I inviting more than just pint-sized guests? I'm probably worrying too much about this. My latest idea is to have pink and chocolate frosting. Or maybe a Pink Panther cake. That would put my cake-decorating skills to the test. What's a mother to do?
