My grandchildren call me nana. It is what I called my grandmothers on my moms side and I like it. My step grandchildren call me by my name, 'because I am not their grandmother." Sometimes being a step is NOT FUN!!! But I don't have a good relationship with any of his children, so I expected it. And it's ok. Just lesson learned...no men with children will ever be in my life again (hence won't be dating again..lol)
