All infants, particularly those with colic, need to be fed on demand and not by a specific clock schedule. Often a baby’s cry is triggered by discomfort caused by low blood sugar. Unlike adults, infants do not have a carefully regulated ability to maintain healthy blood sugar levels in the absence of food. This physiological shortcoming of infants can be solved only by feeding on demand.
In one trial, parents were taught not to let babies cry unnecessarily but rather to attempt feeding right away in response to the infant’s cry. If that failed, parents were taught to try to respond to the cry in other ways, such as holding the infant or providing the opportunity to sleep. These parents were also given the solid medical advice that overfeeding is never caused by feeding on demand nor will the baby be “spoiled” by such an approach. As a result of this intervention, colic was dramatically (and statistically significantly) reduced, compared with a group of mothers given different instructions.
