I think Jiblet is one of those nicknames that "works" no matter what the real name is. It's such a silly family pet name that it doesn't need any support or explanation, like when my friend calls her son
Asher "
Ham" or "Hammy". It's a private joke. So I'd tell her that.
I can't think of any names that would sort of connect to Jiblet... Maybe
Juliet??
Virginia "
Ginny"?? Um.... Jebediah?
Jiblet is a cute word but I don't know how I'd like it as a family nickname. My grandpa used to call me "Muskrat" and I hated it, I felt he was making fun of me. But maybe if a family is actually loving, a kid wouldn't mind a strange nickname relating to chicken guts.
I love that story about calling
Miriam Poppy before she was born! No kids here, but I remember my aunt called my cousin "The Alien" when she was pregnant with her - because the ultrasound pics reminded her of the Alien movie creature.
