Parents often perceive infant gastroesophageal reflux (GER) as a serious problem. Frequently, GER is explained as a normal process, but there are instances where parents’ concerns are valid. Provided are 3 case studies from the private practice of an IBCLC. Each case initially presented with what sounded like normal infant GER. Upon further evaluation, with close follow-up and more detailed history taking, each case required advanced medical attention. These cases highlight the unique role of the IBCLC in helping to assess GER, the value of working as a team member with baby’s physicians, and the importance of listening carefully to parental instincts and concerns.
