+1.
But I personally think that your SIL is being a disrespectful b**ch. Someone should get to choose what they get called. How would your SIL like it if you didn't like her name, so you just made one up that you called her because you liked it better. We let both grandmothers pick the name they wanted to be called and even if I think one of them is silly, we still call her that and make sure that the children call her that, because that is what she wants to be called. I would no more change that than ask her to change her first name because I didn't like it.
