I know not again with Grandmother..ok everyone please help

ok i need help with how to pronounce these and what is the true word for grandma- grandmother in TRUE POLISH-

please like this- BUSIA- BUSH-A??
THANKS SO MUCH EVERYONE, I AM A FIRST TIME GRANDMOTHER AT 39 YEARS OLD ANDBEFORE MY GRANDSON CAN TALK I WANT TO FIGURE OUT WHAT HE CAN CALL ME IN POLISH, MY DAD WOULD BE SO HAPPY

BUSIA?
BOUSCHA? PLEASE PRONOUNCE ALL ..THANKS
BABUNIA?
BABCIA?

IS BAB-PRONOUNCED BOB OR BAB

that's the official one you find in a dictionary,

babunia, babusia are diminutives, while busia is a shorter form of babusia (and I don't hear it in Poland, but I read on these forums that "busia" is common among American Poles or Polish Americans, if you prefer)
and when kids start talking they rather use "baba", as they can't pronounce more difficult words for some time :)

for pronounciation, copy and paste the words into:
ivosoftware.com/
(try both female and male voice)

babcia and babunia are pronounced with a BA
babcia: bab-cha
babunia: bab-u-nia
Congrats on becoming a grandma!

oh, I should've have said that too, sorry for being rude, mypips33 :)
