Let her know any name that's not similar to "mom" or "mommy" works for you. You can recommend some (Grammy, Deedee, Nana, Nan, Granny, Gran, etc) if you think she'd be receptive, or you can just leave it at that.
OP again. Thank you! This is exactly how I'll explain it. I'll agree that she's totally right that two grandmas is confusing but I also think having to "mom"s is confusing as well. I'm totally fine with any other name!
I'm sure it's fine if you grew up with Mom mom as a normal grandmother name, but my husband actually calls both his grandmothers "Grandma." So it's not like it's some sort of family tradition she's trying to continue.
