Are you giving your baby their father’s last name?

I believe it is quite primitive for the baby to get the father’s last name only. It should either be both parents’ or a completely new one. Some women I know have used their family name as baby’s middle name but it isn’t the same thing.

My husband understands this view however he is not in favor of using a completely new name as the last name. He has a 11 letter last name and I have a 4 letter last name. For convenience, I think the baby should use mine but he wants the baby to have both. Any advice on how to navigate this? What last name did you chose for your baby?
