OP, I've sort of been in your position in that 3 weeks before DD2 was due DH decided he didn't like the name. He would never suggest any names so I gave him a list of 5 names to choose from and he didn't even look at it. When DD2 was born he straight away said she was the name he previously didn't like. If he had chosen another name from the list I would have been disappointed as I loved the name I really wanted but I would have gone along with his suggestion.
now for the funny part.....4 years down the track I wish DH had chosen another name as DD2s name is so popular and as much as I think it's a beautiful name I regret using it.
