Bayla is nice.
What about using Lynn as inspiration? Linit is pretty
I like it! It does go well with Jonah and the nn Bay is really cute. In case you were still interested in other names, here are some that I found..
Babette (Means my God is a vow)
Yeah, I like Bayla better ;)
Bayla is pretty but Bayla and Jonah. I don't know, they both have the a ending. Barry means spear so, other names meaning spear are...
Corin- Jonah and Corin...
Adair- Jonah and Adair...
Corin Bayla? Jonah Elias is a great name!
You could just call her Bay. :) How about Beatrice? Or Bea? I like Bayla, but it seems like a mix of Bailey and Kayla. Which could be good, since it will feel familiar... Easy to pronounce, too. I love your son's name, by the way.
