EC = The acronym/abbreviation for elimination communication (see below).
Elimination Communication = Elimination communication is a practice in which you try to use timing, signals, cues, and intuition to address a baby’s need to eliminate waste. The goal is to try to recognize and respond to babies’ bodily needs and enable them to urinate and defecate in a toilet or potty so that it’s natural for them from the start.
