CaringBridge.org is a wonderful site where families who are experiencing medical trials can keep loved ones updated. It is totally free and very easy to use. A nurse in the NICU told me about it, and it was so helpful because I didn't feel the need to be on the phone all day updating people (as much as I loved that people cared, it was very overwhelming). Not to mention, writing the posts was very cathartic to me.
You can read the story of my pregnancy here. The Journal tab on the site is where I would write to keep people updated on the news. It's a roller coaster filled with medical terminology and Bible verses, and you can see it here.
