Which do you like better?

So my fiancé and I had such a hard time agreeing on a name that we both liked. He would pick names that were seriously just corny as hell, for example Yukon Cornelius, Tiberius, etc. So when he mentioned the name Dax I was like that's one that I don't hate! And ever since we've been calling him Baby Dax. I still have 11 weeks until my due date, but as time goes on the more I think that Dax is just too short and it needs something added to it. I like Daxtin, and that way he can still call him Dax but of course he doesn't like that. Suggestions? I'm open to new ideas!
