The mother-infant bond is the familiarity and attachment that a mother forms with her offspring. These helpless babies depend on their mothers' care to survive. This dependence goes beyond a physiological need. Infants rely on their mothers to fulfill a wide variety of demands. The mother-infant bond is essential to maximize the fitness of each individual, as well as the growth of the species. In 1976, Marshall H. Klaus and John H. Kennell published a book called “Parent Infant Bonding.” He discussed their hypothesis that, as with other animals, there is a brief time immediately after the birth of a child where skin-to-skin contact between mother and offspring creates a strong bond. Although this theory continues to be supported by many, some have criticized the process of Klaus and Kennell's studies. Some of this criticism likely stemmed from their definition of a “critical” period after birth. According to Klaus and Kennell, there are specific events, including skin-to-skin contact between mother and child, that must occur immediately after a child's birth. baby primate. This maximizes the newborn's chances of survival, not only because its mother is a source of food, but also because it will learn the culture it needs to succeed in its environment. In the study, Klaus and Kennell test how much time a baby spends crying when separated from its mother. They concluded that the increased time spent in separated babies was due to anxiety caused by separation. The difficulty is that the cause of the baby's distress is subjective. Furthermore, the notion of a critical period suggested that the connections and lessons taught during this period could not be developed later.
