This paper has two major purposes: first, to consider how infant feeding behavior may fit into attachment theory; and second, to cite some evidence to show how an infant's early interaction with his mother in the feeding situation is related to subsequent development. It was found that sucking and rooting are precursor attachment behaviors that may become tied into the attachment system if a baby is allowed much initiative in attaining the breast, but that the behaviors do not necessarily become so. From an analysis of mother-infant interaction, it was concluded that the feeding situation does have a significant relationship to the kind of attachment the child develops, to later problems in feeding, and even to later so-called 'oral' problems that are not directly related to feeding. One of the conclusions of the study was that the time has come to reopen the issue of the effects of breast versus bottle feeding on both maternal behavior and infant behavior and the interaction between them.
