When I was pregnant with my daughter, a colleague tried very hard to convince me to call the baby "Flash". He would ask after "little Flash" and it got to the point, with my pregnancy addled brain, that I could have considered it.
Fortunately, my husband put his foot down and she has a very traditional name that I love.
My new daughter's wombname was "Pending", and it was hard for the midwife to start calling her "Alexandra". Her older brother was "the Tykelet". My all-time favorite, though, was the daughter of a friend, whom I christened "Ember" because her father's surname is Cole.
