We always called my grandmother Babchi (bop-chee) or Baba (Bah-bah) and my grandfather was Dadju (Dah-jooh).
I was always told that Baba was Ukrainian and Babchi was Russian. When our first g-child was born, we pondered, as Busia (which signifies "old" to me) and Bunia were taken.
Hubby's sister in Indianapolis adopted Bunia for herself with her g-children, and so it continues... I grew up with a Babcia, a Baba, a Bamboo, and a Grandpa.
My Babcia was 100% Polish and this is the name for Grandma.
My little daughter caught on quickly when we taught her "G G B-ma" for Great Grandma Bess and "G G O-ma" for Great Grandma Olga.
Babci & Dziadzio: Hubby and I are each 100% Polish, and when we had our first, his Mom was already called Busia ( again an Americanized version of Babcia), and my Mom became Bunia, a shortening of the derivative Babunia. So I became Babci (it is even on my license plates! It is a lot easier to have Babci and Dziadzio on one side, and Grandma and Grandpa on the other ( our SIL is from good, Iowa stock).
It is, however, more difficult for our older g-child to explain to her Iowa friends what Babci and Dziadzio mean, than say, in ethnic Chicago!!!
They call my mother butter-butt because while they were camping, she backed into a trash basket and got a butter wrapper stuck on her butt.
Recently we had our first son, and my in-laws wanted to know what they should be called.
