Oh my. Zoee has tons of nicknames. The generic ones - Zo dog, Baby Girl, Poopy Loopy and anything else that comes to mind at the time.
But the only one that has any kind of story behind it would have to be Badonkadog. It is, of course, after the Trace Adkins song - Badonkadonk.
I sing it to her but change the end to dog instead of donk.
