I've had my little girl's name since I was 18 and listening to a radio program about the Bible on my way driving back to college. (It's a long story, Sara has evolved from Seraphim angels) But I have no just in case boy's name. You know gender is completely up to the male. Well, DH has not had a girl born into his family in over 40 years, and then it goes another 20 years until the next. I worry that the ultrasound is wrong and want to have a "just in case" boy's name, but for the life of me I can't think of the perfect one. For DS we actually decided on his name by looking through the phonebook. You'll come up with a name. I'm sure the perfect name will just suddenly be there in front of you, even if you don't find it until after the babe is born.
