My current WIP has a new baby. I have a terrible time naming my characters. I proofed Gypsy twice before I realized I had characters named John, Jon, and Juan.
A lot of new babies (especially celebrity babies) have just awful names. An actress named her baby girl Lincoln, for pity's sake. That's a terrible name for a boy! Poor kid. And Mila Kunis just named her baby Wyatt. That's a cool name for a boy, but the poor baby was a girl. Sigh.
In a nod to terrible names, I named the baby character Amygdala. That sounds familiar because you heard it in Biology class. It's part of the brain, and it's responsibilities include emotional responses. Her mom didn't know that until another character pointed it out, and by then it was too late to change.
Other brain-related possible names: Frontal Lobe (a good name for a band), Pituitary ("Pit" is a cool nickname), Spinal Cord (hasn't that been done?), and--my personal favorite--Brain Damaged (my dog responds to this one, but not every time).
In my daughter's class there was a boy named Colon. Really? Do you not know that is also the name of a chunk of your large intestine? Why not name the poor kid Sphincter?
I have to go. My son Arm Pit and my daughter Uvula need to go to therapy.
