Bear: For our 9-year-old boy.
Mouse: For our 7-year-old girl.
Jaybird: For our 4-year-old girl.
Mudpuppy: For our baby boy. Yes, it's the name of a salamander, but it sounds cute.
And "Jackrabbit" for me and "Starling" for my darling wife.
Hopefully these will stick, cause if they don't, I'm going to numbers.
