Maybe you should each get to name one of them. I personally don't like when twins have two similar names. So you should each get to name one that's what I would do.
Put the names together. Makayla Jalynn, and Jayla Mckenzie. That way both sets of names are used and they're not to identical.
Jayla and makayla! Compromise!
^^^ compromise... But I like jayla and jaylnn better...
Definitely compromise. They are his babies too, he should have a say in it.
