We are a big nickname family. In fact, virtually none of us (including our extended family) go by our real names. We're a crazy cast of characters that include Goopy, Grumpy, Mug, Boots, Bubbe, Tari, and Mr. Aaron. Basically the only ones in the family with normal names are my sister's dogs - Chloe, Bonnie, and Macy.
Cade's in utero nickname was Kid Fox. When he was born we started calling him "Bird" because he was covered with soft, downy hair and opened his mouth like a baby bird when he was hungry. I now realize this is not horribly original and basically describes all infants, but hey - we were first time parents. And so he is Bird to this day.
And then along came Drew. His fetal nickname was Bob. When he was born, Cade called him "Bubbo" instead of "Brother", and eventually that got shortened to "Bub". Which, ironically, is pretty close to Bob - he came full circle.
Enter Josh. The boys named him "Pawl" (Paul with a VERY southern drawl) before we even knew if he was a boy or a girl. Now he goes by one of two names. Sometimes he is "Baby" (see this post for the backstory on the origination of this name). And of late, Aaron has been calling him "Toad" because of his melancholy nature and his startling physical resemblance to Toad in Arnold Lobel's Frog and Toad children's book series (a Fox Family Favorite).
Here is a side-by-side comparison:
