Boy or a girl?

I think it will be fine for a girl, but I know 3 guys named Skyler and no girls. Maybe consider switching the order to Hailey Skyler, that way you could call her both and just see which one suits her as she grows into herself. Some of the most beautiful people have not so beautiful kids, and you wouldn't want her to be teased throughout life if she isn't super girly. Good luck with deciding!!
