Curious if anyone has done this!

DH and I had a heck of a time coming up with a name for our unborn son. We finally settled on the name Oliver and shared it with friends and family during the holidays.

Then, recently, DH told me that one of my favorite boy names, which he has always vetoed in the past, had actually grown on him. The name is Joshua. I am so torn! I love the name Joshua, and can totally see naming our son that, but we've been calling him Oliver for months, and so has everyone else! Anyone change names at the last minute? Would you consider it, given this scenario?
