We have been referring to Abbey by her real live name long enough. Obviously if DOB and I have online identies (actually a whole host of them, but only one each for purposes of this blog), she should, too.
The question is, what? I am inclined toward picking a title that can apply to all future offspring, with the addition of a number. Two ideas that come to mind:
Hobbit (H1, H2, etc.): She's short, cute, and likes to eat six meals a day (and two a night). She also has big feet, but they are not hairy.
Duckling (D1, D2, etc.): It just seems logical to me that the inhabitant of a duchy should be a duckling.
