Layla,
Laila,
Leila, and
Leyla are all LAY-la to me.
Lila and Lyla are LIE-la.
Laelia I would say LAY-lee-uh.
I don't know many Laylas, but my friend in a different state says she's heard of tons of young Laylas. (She always wanted to name a daughter
Leila, but it got popular so she ended up naming her dog
Leila instead.) I only know one
Lila - she'd be about 5 now, I think? Never heard of
Laelia before.
I like
Lila spelled Lilah. I don't really care for the others.
