This advanced practice presentation is intended for an audience of IBCLCs. Most infants suck correctly given normal anatomy, an optimal latch and normal milk flow. This presentation focuses on some strategies to assist infants who do not. It builds on the information given in Anatomical Contributions to Infant Sucking Skills. The function of each oral and pharyngeal structure in sucking is reviewed, potential issues with each structure are discussed, and strategies to help improve sucking function are presented. Clinical photographs and video illustrate the techniques taught.
