Acceptable nicknames include Goose, Lulu, and variations of both.
Despite the endless options for addressing my sweet little Goose, there are A LOT of people that like to refer to her as "the baby":
"Are you bringing the baby?"
"How's the baby?"
"I want to see the baby."
She is a person, just like you and me. How would you like to be called "the girl" or "the boy"? Parents don't debate over names for months and months to have it completely disregarded.
