We went through that a lot prior to the birth of my son. Prior to even getting pregnant, I had tons of fantasy baby names (most of them girl names, however). When we found out that we were having a son, I was thrown for a loop. It was so hard deciding on a name.
I eventually wrote a list of all of the names I liked, handed it to my husband and had him pick from that. Of course, he didn't like any of those either. About 2 weeks before giving birth, DH finally suggested a name. By that point I was so fed up and exhausted that I would have agreed to "Boy" if had suggested it.
But the name he chose was very fitting (Brendan), and I couldn't imagine my son having any other name today.
Best of luck with your decision!!
God help us if we decide to add to our family down the line....
