Why is he the little plum? Brandon named him this, when first we learned of his new in-utero existence. I asked Brandon how he came up with it, and all Brandon said was, "I just say awesome things sometimes."* So there you go.
Personally, I think it stuck because we needed a good gender-neutral way to speak about "it," and neither of us were very fond of the more common "little peanut." I like peanuts, but they are kinda static. They are just waiting around. Plums, on the other hand, are luminous and shiny and growing. They ripen. And doesn't it seem sort of grand, to be able to make a bright little fruit? It was a nice way to think about being pregnant.
*Prior to conception, Brandon had once suggested that our offspring should be named "Jinxy McTwatstretcher,"** which is catchy too, but you can see why it didn't take.
**I just asked B if he thought it was inappropriate to mention this name here and he snorted and said, "I'm funny." Then he sang a little song: "I think I'm funnnnnyyy...do you think I'm funnnnnyyy? Probably..." to the tune of "Crazy", the current pop song by Gnarls Barkley. (To hear this song instanter, link to the iTunes Music Store here -- blwh)
