Need opinions...

So I'm 23 + 3 with a baby boy💙 well hubby and I can't come to an agreement on names for our son. We have a daughter already and I choose her name (he agreed of course) but he wants to have a jr and I'm not really into that idea. I feel my son should have his own identity. But hubby feels strongly about naming our son after him. Should I just let hubby make the final decision? Should it be a mutual agreement? Help!
