Hi J.,
Congratulations on your new son! Babies are the most wonderful blessings we ever get, aren't they? I have not gone through this specifically, but thought I would put my ideas on the table for you to use or toss as you see fit!
I think an email or a written/computer made birth announcement would both be good ways to communicate with your friends. I would include his diagnosis in context with ALL of your most up to date information on him: His smile, his disposition, his like (or dislike!) of baths, etc. After all this diagnosis does not solely define your son. If it were me, I would make it a very personal announcement with details about him and a few pictures. (You probably have about 2000 by now, at O. month!)
I thought a nice way to phrase it is given in an article I linked below. It is the way O. family announced their son's Down Syndrome in their holiday newsletter. Until the father took a job for the Down Syndrome Research and Treatment Foundation, they chose to never formally announced it. They let people hold him and love him and then explained his condition, once the family members, friends, etc. had gotten the chance to meet their son. Their wording follows:
"Evan is curious, rambunctious, playful, affectionate, vocal and determined." They told of their recent travels with Evan to Singapore, Sweden and China.
Then, toward the end of the letter, came the words they had thought about for so long and chosen so carefully. "Evan was born with Trisomy 21, a genetic condition," they wrote. "He has three normal copies of his 21st chromosome, whereas most people have two. This is a fairly common condition, also known as Down syndrome."
There seems to be two camps of thought on this:
1. People who think that it is best to announce the news to everyone asap

and
2. People who don't want to formally announce it--ever.

I think an email would, indeed save you telling and retelling your story and it is O. way to quickly and thoughtfully spread the news of your family. Again, congratulations to you and your family.
