Baby name problems

Ok so my hubby and i have 3 daughters, i named the first his sister named the second and we both picked the 3rd.....the issue is we are finally having a boy due August 4th and i dont know how to feel about the name hubs has chosen, we had agreed on a name but now out of here nowhere its changed.. I get he wants to name his son & last child (getting tubes tied) but i just dont know what to do😔
