My husband vetoes EVERY SINGLE NAME. It's not a new phenomenon. He just likes very classic, plain names and if I bring up anything even slightly trendy or slightly interesting....automatic veto.
Right now we have not a single contender for DS3 because of this! The only names he has suggested are: Matthew and Collin. He likes Grant (which I also like) but doesn't like the fact that it has no nickname. Luckily, we have about 5 more months to decide, I think we'll need it!
