My biggest problem? I can't figure out what to call baby #3 before he/she decides to join us.
Brooklynn was Beta (for beta release version)
Maddi was Artoo (for R2, or revision 2)
I'm halfway tempted to follow the Star Wars convention and go with Threepio, for C-3PO, (using the C3 for child 3...), but I haven't committed to that. Feels a little contrived.
Brooklynn suggested Molly which was nixed for being too gender specific. Maddi contributed her idea of "Baby". Real original, honey.
So, baby #3 for now.
