Telling me what I can't name my baby if it's a girl!!

So my husband and I have been discussing baby names since I can remember. Now that I'm actually pregnant, I'm more determined to find a girl name that I'm satisfied with... So I picked the name Haisley Because I've liked the names Paisley and Hailey and wanted to combine them. So a friend of mine messages me and says that that's her baby's name and that I should find a way to spell it differently or not name my baby that at all IF ITS EVEN A GIRL. She calls her baby by her middle name so I never had any idea that that was her name... But I've had this name for years..
