I discovered the work of Gwen Dewar, Ph.D when ParentingScience.com covered her 2008 work on breastfeeding on demand, also known as "baby-led" and "on-cue" feeding. The basis of this practice is that babies, with the means they have developmentally at their disposal, initiate feedings with their mother. The feeding sessions begin with the baby's request and finish when the baby is satiated.
Dr. Dewar shares, "Evolutionary, cross-cultural, and clinical research suggests that babies were designed to feed on cue. For details, see my article on the scientific evidence for breastfeeding on demand. Here I provide an overview of the benefits of breastfeeding on demand and focus on the ways that new moms can cope with frequent, baby-initiated feedings.
Women living in Westernized, industrial societies face special problems that can make demand feeding more difficult. I discuss how babies are breastfed in other cultures and suggest how Western moms can apply these lessons to their own lives."
