The understanding of infant sucking has burgeoned in recent years with the continued development of cineradiographic and ultrasound techniques. A clear understanding of how infants use the tongue during breastfeeding as well as triggers for infant feeding behaviors helps the lactation consultant understand how to optimize attachment for each mother-baby pair. A wide variety of approaches to both mother and infant led attachment are illustrated by video clips from lactation consultations. Extensive clinical photos illustrate the subtle signs of suboptimal vs. optimal attachment. The longer version includes latching to bottle nipples to support breastfeeding skills, optimizing attachment when using at-breast supplementers, and latching to nipple shields in a way that promotes direct breastfeeding in the future.
