Naming debacle!

Michelle
It is very early in my pregnancy but I can't help but think of names now. This is my husband and I's second child. Our first, our first is Greyson. When I was pregnant the first time around my husband and I adored the name Olivia, still do but it is so popular. I started thinking of new girl names and I love the name Emilia. I even like all of the possible mispronounciations and nickname options (Emi, Millie, Mila, Lia, Mia) but my husband doesn't like the spelling. He like Amelia, but I just don't feel the same about that spelling. I don't know how hard to push for a name that he doesn't like. I have heard several people my age say that one of their parents didn't like their name when they were born but grew to love it. Can I just pull rank and use that name even if he really doesn't like it?? I'd love your opinions!
