my mom doesn't seem to like any of the names we've chose

Ka
I'm feeling torn on names now since I told my mom the top three. 
We really love Savannah, Olivia, and charlotte. Her middle name will be grace.
I also think that her not having my moms middle name is also bothering her.
But she just gave me a funny look when I told her the names and it really makes me feel some kind of weird way, because it's my child and those are the names we like, it's our choice. And it shouldn't bother her in my opinion. She didn't see to care that much when my sister was naming my niece, and I think that's because they gave her our mothers middle name. Am I crazy for feeling the way that I do? 
I have always felt a sense of disconnection and distance from my mom and was hoping that this pregnancy would bring us closer, and she loves my bump but almost everything else seems to be a struggle or like I'm wrong no matter what :(
