I also LOVE Delaney, but when I was pregnant with my son, my sil named her daughter Laney, so I didn't use it for my next daughter-too similar, I like Delaina, I don't care for the spelling Delayna, just my issue, but I have a problem with names within names (delay), and I think Laina would be a really cute nickname, I think Kate is perfect for a middle name, very simple to go with the first name which is kind of elegant I think-so, perfect combination!
