Examining the Evidence for Cue feeding of Breastfed Infants. A technical article by Lisa Marasco, BA, IBCLC and Jan Barger, MA, RN, IBCLC. “Babies, most especially breastfed babies, need to be fed on cue and should be allowed to set their own routine, rather than placed into a predetermined schedule. It is our further conclusion that practices which interfere with respecting babies’ cues have been responsible for low weight gains, failure to thrive, milk supply failure, involuntary early weaning, and possibly even some cases of colic, not to mention infant regression and depression due to lack of parental responsiveness to baby’s frantic cues.”
