We've have been cuing and watching Ema's potty signals since she was about 3 weeks old. Today I held her over the big potty for the 1st time. O and I cued her and she pee-peed! We were so proud :) O was especially excited! Click here to learn more about EC. I highly recommend this book if you are interested in using this method with your baby. We were lucky that our local library had a copy!
