It is normal for infants to cry in response to fear, stress, sleepiness, or pain, or when they wish to request food, entertainment, or comfort. Yet, such cries, when frequently unaswered, are responsible for much of the stress that interferes with the attachment process and causes brain cell death, stress control disorganization, adolescent behavior problems, and physical and psychological difficulities in adults. Since crying is exhausting to the infant and mother, both mentally and physically, it is understandable that mothers feel the urge to answer crying quickly. A mother attempting to ignore crying also becomes quickly exhausted because she is being helplessly exposed to prolonged and annoying wails. She also becomes flooded with cortisol. Responsive parenting is best for an infant in terms of immediate safety, health, and comfort, as well as for long-termm development. It is healthier and generally more comfortable for mother, too.
