Happy News....and Name Drama?

First the great news, J's sister had her baby early yesterday morning!  She waited to find out the gender and it's a little boy.  It sounds like her labor and delivery went exactly as she had hoped which is wonderful.  Unfortunately, the baby had some issues with meco.nium and had to be admitted to the NICU :(  It sounds like he will be fine, but will have to be there for a few days.  My in-laws left last night to drive the 12 hours or so to be with them and meet the baby, so hopefully we'll know more after they arrive. 

I'm 37 weeks and 5 days today.  With my SIL now actually having her baby (at 39 weeks and 3 days), it's hitting me that I could actually be having this baby very soon!  I think we're ready in most areas, but now of course, we've had some drama arrive with our name choices!  We've had a list of 5 names that we liked for a long time.  Our plan all along was to not share the names with family, friends, etc. (just to avoid the 'helpful' suggestions) and make a final decision about his name after he was born.  That way we could make sure the name was perfect for him, etc.  The past few weeks I've started to really feel like our top name choice was the one and so did J!  Of course, I was still planning to wait until after he was born to make sure, I wasn't ordering personalized gifts or anything. 

My SIL and her husband didn't find out that they were having a boy ahead of time and yesterday they named him Richard and will call him Ricky.  Our first choice name at this point was Nicholas but we would call him Nick.  Last night J pointed out that as they got older, they would probably go by Rick and Nick and would that be strange for cousins the same age to have names that rhymed?  Hmmmm.......I actually hadn't thought of it before then and now I'm super concerned about it.  They have different last names and currently we live several states away from each other and don't see each other a lot, but still - I'm starting to panic and wonder if I should give our name list more thought.  So, I'd love your advice - is this something you would worry about?  Or do you think the names are so different that we don't need to worry about what the other kid would potentially go by later in life?
