I must start by stating that my dm is absolutely AMAZING in every way and I trust her opinion on everything 
Which is probably why I'm finding it so annoying that she doesn't like my choice of Kitty if I have a girl. (She likes all my boy choices btw).
She says she is surprised that I am going with something so plain after all the other lovely choices I have suggested over the three years of ttc with fertility problems. (The problem is that all of those lovely names just don't feel right). She says it is a nothing name, though she said this about my ds name but adores it now. She thinks it is an old ones name and nothing special.
I think that it is quirky and old fashioned but not batshit crazy which is what I am going for. Dh loves it as do I. Oh and btw the issue is nothing to do with putting something longer on the birth cert! 
I don't really know what I'm asking, I think I just want to vent!
