Plan of action was to wait till she was born and then just look up at him and say "Arika" ... with a smile. I mean, he can't say no to me just after I have been through labour can he?
I'm having the same problem with my DH and this is my plan too (but replace Arika with Amelia). He just won't discuss it with me. Everything I suggest, he shoots down and the best he has come up with is "Stephanie". Hmmm. Nice enough BUT it doesn't go with our last name and I have an ex called Stephen so I'm really not a fan. So - you're not alone! I don't think I can help much with names as you seem to like different names to me but I'll give it a go.
