I'm going through the same thing, as I'll become a father by the end of Nov. Choosing a name has been tough, especially cause my wife likes names I know I'll have troubles with (she likes the R letter, which gives me nightmares... for reference, my name is full of R's and had been struggling my entire life with it). Overall I think we'll go with "Noah", it's very short and easy to pronounce. All of this to say that I perfectly understand what you're going through. I wish I could tell you, as others did, to stop worrying about that but unfortunately being in the same situation I can only be honest about it.
