I don't really have a strong opinion on this name. It's fine I guess. If you like this name, give it to your child. There isn't anything wrong with it. You don't have to agree with my opinion though. :)
Jaylen is a sweet name. I actually think Jaylen is more suited as a girl’s name. It’s especially feminine because of the -len at the end. Please accept this as my guilty pleasure name for a girl. I know it’s supposed to be a boy’s name, but I much prefer it for a girl. I can’t believe how much people hate these names, I think they’re pretty.
If a name sounds anything like 'jailer', 'jailee', or 'jailing', it would be better to choose some other name. This name is lazily constructed and trashy.
I named my daughter Jaylen. I think it sounds more feminine than masculine. I looked up J names and it was listed in the girls section and I fell in love with it. I think the name fits her and I had never met a male Jaylen before. It sounds close to Jaylene to me. I'm glad to see it gaining some female popularity though.
