The first time I heard about this, it blew my mind!!

"Elimination communication (EC) is a toilet training practice in which a caregiver uses timing, signals, cues, and intuition to address an infant's need to eliminate waste. Caregivers try to recognize and respond to babies' bodily needs and enable them to urinate and defecate in an appropriate place (e.g. a toilet). Caregivers either use diapers as a back-up in case of misses, avoid the use of them altogether, or do a mixture of the two. EC emphasizes communication between the caregiver and child, helping them both become more attuned to the child's innate rhythms and control of urination and defecation."

Is anyone out there doing EC? Was thinking about trying it with baby #2, and would love to hear some personal experiences!
