Don't like 7 month olds name

I had the hardest time naming my second child that we left the hospital and he had no name... For about a month. I flip flopped and tried calling him Rylan but it didn't feel right and then I had a dream and his name was Rocklan. I thought that has to be it! So we went with Rocklan Henry and I didn't love it. No one did really. Now that he's getting older  and I say his name more, I'm finding I just don't love it.... I think I want to change, but don't know to what. His brother is Eli so something that flows I was thinking. I feel horrible about the whole thing. What does everyone think of a name change? Suggestions as well.  This is him!
