SAN FRANCISCO—Three days after giving birth, first-time mother Courtney Baldritch has registered with the web service WordPress for the purpose of blogging the severely underdocumented experience of child-rearing. "Now I'll be able to preserve for posterity every detail of this magical time in my life and in Kaylee's, recording every decision that affects her as well as all of my personal thoughts and reflections on the process," Baldritch told reporters Saturday. "At long last, persons wondering what valuable insights fertility has imbued me with, or just wanting to see pictures of my precious Kaylee, will have a one-stop resource in cyberspace." Baldritch estimated the odds of her updating the blog twice a week for three weeks and then abandoning it at zero.
