Caribou Baby, a Brooklyn, N.Y., "eco-friendly maternity, baby and lifestyle store," has recently hosted gatherings at which parents exchange tips on "elimination communication" — the weaning of infants without benefit of diapers (as reported in April by The New York Times). Parents watch for cues, like a certain "cry or grimace" that supposedly signals the tot urgently needs to be hoisted onto a potty. Eventually, they say, the potty serves to cue the baby. Dealing with diapers is so unpleasant, they say, cleaning an occasional mess becomes tolerable. The little darlings' public appearances sometimes call for diapers, but can be handled by taking the baby behind a nearby tree. One parent even admitted, "I've absolutely been at parties and seen people putting their baby over the sink."
