BF will not stop about naming our son(if it's a boy) Lucian

Kayla • 17 and proud to be a teen mom. I wouldn't change it for the world! He is my little blessing❤️
Help! What do I do? My boyfriends wants to name our son, if it's a boy, Lucian, I hate that name. I have him a list of 20 names that I liked and he hated them all... He even hates Madiosn Faith for a girl. He said, if I can't name him Lucian you can't name her Madison Faith
