In all areas, babies are taught to obey at levels that are not consistent with their capabilities. This skewed perspective results in what could be dangerous interpretations of a child's behavior. The program's firm stand against nursing on cue is refuted by Dr. Lillian Blackmon, AAP Member Committee on Fetus and Newborn, neonatologist, and faculty member of the University of Maryland School of Medicine. There is no scientific evidence for any species, including the human being, that forced scheduled feeding is in any way superior to demand feeding. Adults would never accept that.
Hunger is a physiological response to the absence of food.
Dr. Blackmon doesn't consider crying a negative behavior. I consider it a communication. It is not wrong to go and pick the baby up to comfort it. It reinforces the trusting bonds between the infant and the parent. And the infant has a limited repertoire of ways to bring those needs to the attention of the adults.
