K.,
I just wanted to jump on the "you're a great friend" bandwagon. 3 years ago my son was born at 29 weeks, no heartbeat and he was not breathing at birth - it was a very scarry time for us (by the way, he's perfect now!). We lost a lot of friends through our 3 month NICU stay simply because people didn't know what to say and felt so uncomfortable that they just sort of layed low when we needed the love and support of our friends.
Be there for your friend. Make them dinner, drop off a book or magazines for them to read while in the hospital, do little things - even just a phone call to let them know that you are thinking about them and wondering if they need anything (even mention that you know that they are busy, so a return phone call isn't needed).
I will keep their baby in my prayers. Medical advances are so amazing these days, the doctors will do everything they can. I know nothing is for sure, but he certainly has a great chance of pulling through this with little or no complications. Please feel free to email me with any questions.
B.
