By checking the Google key words, I figured out that I'm getting several hits a day with questions about what two lesbian moms are called by their kiddo. Although I asked how others handled this issue a few months ago, I'm not sure I ever returned to the topic and explained what we decided to do.
No drum roll, please.
Marcia is Mama, and I am Baba. Why? I'm not entirely sure why. We really wanted two names that sounded distinctly different to a child's ear. We have friends who are Mama and Mommy, and we wanted to have names that would be obvious to Pearl, even at a young age. The B sound was one of the first sounds she could say.
In some eastern European countries, kids call the grandmother Baba. We have a storybook called The Mitten that has a boy and his Baba. As I was writing this post, I did my due diligence and looked up the word. Unfortunately the definitions are: (1) a very old woman, and (2) a rich cake soaked in rum and syrup. Ah well!
