Opinions on baby girl's name?

I'm sO shocked that we're having a girl, my guy feeling was so strong I was convinced she was a boy!! We're almost sure of her name - Hollie Roo Simper♥️ My main concern is her middle name, is Roo a bad choice? I think it's adorable and will make a lovely nickname (I've already started since shes always bouncing around on my bladder!!) but am concerned it's too cute, and later in life will cause her issues in trying to be taken seriously? Please leave comments, anything is welcome! Honesty!! x
