I call my oldest granddaughter (who is 16 now) Sweetpea.
My husband's nickname is Hamster Man. I guess because he has a furry face and is round and happy like a hamster.
I used to call my youngest daughter Julie, boo-ba-la when she was little. Sometimes I still think of her as my little boobala, even though she has Sweetpea and four younger children.
My husband calls me Deara, no one else we know has that endearment for a nickname.
Merry Christmas!
Blessings to all,
Sandi
