baby name

Meg • Due with baby#2
So my babies father has had Both gender names since we found out I was pregnant. We recently found out it's a boy and he wants to name the baby after his late father, I think it's such a sweet idea but I can't seem to get my head around the name his chosen. Every time we try to compromise it turns into an argument. How do I tell him gently I'd rather the name as a middle name? I don't want to seem like the wicked witch of the west..
