Losing Sleep!

I can't decide on a name for little sis!  I mean I tell everyone I talk to that we've liked a certain name for a really long time and I still love the name but the reaction from my side of the family has me losing sleep at nights over it. I've spent at least 5 hours altogether in the middle of the night just this week thinking only about this.  I honestly can't think of another name that I like. Why is naming a child so hard??? Why do people have such strong opinions? And then if we do end up defying my family and naming her what we want I can't think of a middle name. Ugh!!!!!

The big problem is that I have specific requirements for this name like:

• I can't have had a student with the same name. This limits the list considerably when you do an average of 30 students times 4 years. For those of you who don't do multiplication that's 120 names out the window!
• I actually don't want to name our little girl after anyone I know or have ever met. That's what I mean by "Unique". It's not that I don't admire anyone enough to want to name her after them. It's not that I don't love their names either. Maybe I just want her to have a name of her own. Or maybe I don't want her to have the problem of teachers having to say her last name with her first cause there are 3 other girls with the same name. I'm not sure why really. 
• If you would meet someone in an assisted living home with the same name it's not gonna happen, cause I've worked there too. I know those names are coming back but I immediately can smell and old person smell when I hear the name. Dumb I know. Especially when I have a name like that. Anna is an old name and I love my name. Yep, I'm ridiculous.
• It has to have a positive immediate word association.  That's why the name Chester wouldn't work for me when John would say that's what we're going to name Cache. I would immediately think, "Chester the molester". Or I love my Grandma's middle name, Arabelle, but when I think of that name I think of a milking cow. Not what you want others to think of your little girl.
• And... that's another thing. We named our first kid Cache. You can't have one child named Cache and the next child named Sally. That just doesn't work. One name we really like is Valli, but again, when we would introduce our children as "Hi, this is Cache and this is Valli", people may laugh right out loud at us or even worse, them. 
• I also like names that have to do with nature or a place, or can be associated with the month somehow. Hence, Cache. Since this little girl will most likely be born in February I've tried to think of names that aren't too ridiculous. Valentine just isn't going to work for a name. 
• I don't want it to be too trendy. Again I don't want her to have to go by a nick name or be called by first and last name just because there are 3 other Jessica's in her class. Yes, that's happened to all Jessica's I'm sure. But Jessica really is such a pretty name.
• It needs to be able to have a good nick name. I like the name Dixie, but she may get called Trixie Dixie. Not too positive. 
• It must be gender specific. I don't want anyone wondering if she's a boy or a girl. The teacher should be able to look at the student list before she/he sees the kids and be able to put them in a seating chart boy -girl- boy- girl if wanted or needed.

  Yes, teaching is part of the reason I am no longer capable of choosing a name. You can see I need help in more ways than one. If you have heard of any names that fit my unreasonable criteria I would love to hear them. Just know that I may come up with some irrational reason for not liking it so don't be offended if I don't choose it.

Also know that just because I am so picky with my own kids names I have not and never will be as critical of others choices for their own children.  :)
