We started elimination communication (EC) with Oliver when he was 5 weeks old after attending a class on the subject. You can read more about it in this post, that I wrote back in Nov 2009. Since we're now much more experienced, we decided to start it with Elliott at birth. So far it is going great! He's starting to go when we signal, and today he was 100% successful with poops! Quite an accomplishment for a little guy who is only 8 days old. Oliver enjoys helping out, and will often make the "Psssss" signal for him.
