To be honest, I don't really like it and it's definitely not my style...if I could be said to have a style of names! I think
Lynn is very pretty as a middle name, but I can not fall in love with
Sky or any version of it...it sort of sounds like a hippie name, IMO:)
I think I would maybe stick with something you like and have liked for a long time, just so that later on you don't maybe regret giving into pregnancy hormones:) lol
