What I need:
Grandfather (and familiar variations)
Grandmother (I know "babushka", but that seems formal--are there other variations a young child is likely to use?)
Mother/Mommy
Hello (I've been told there are many variations on this, based on to whom a person is speaking and how familiar they are. Specifically, I need a greeting in person to an unfamiliar person, a greeting in person to a familiar person, and a greeting in answering the telephone)
I also need:
"Don't tell your grandfather."
Thanks for any help. I'll probably need some more in the future :)
Edit: I think I've got what I need now! Thanks, guys :D
