Baby name.

While I know it's totally up to my husband & I on what we name our baby, my mom doesn't like the name I have picked out for a girl. (we don't know if we're having a boy or girl yet.) I love the name Calliope. I first heard it on Grey's Anatomy (which is my favorite show) & I fell in love because it's so different. I've been wanting a different name that's not commonly used & Calliope is definitely one of those names. My mom wouldn't never not like my baby because of a name but it bothers me a bit that she doesn't like it. She puts on a weird face when I tell her what the names are (she checks in to see if maybe we changed it) My husband & his side of the family think it's a cute name & different so they're all for it. I guess I'm just looking for advice or just something to make me feel better about it.
