Child abuse and neglect in infancy: sources of hostility within the parent-infant dyad and disorders of attachment in infancy.

The human infant is prepared during fetal life and arrives on the scene ready to participate actively as a partner with the parent in structuring his own development. Parents are normally prepared for this participant activity by achieving a high degree of sensitivity to the signals of distress of and by the infant's affective engagement with them. The meaning of ordinary distress signals is in instances of child abuse and neglect determined by an unconscious mythology which the parent has about the infant, and also by what the parent finds unacceptable in oneself and projects onto the infant. The recent research on mother-infant attachment is reviewed. Landmarks for normal attachment behaviors from birth to age 3 are defined within seven different age groupings, and the psychiatric syndrome, "Reactive Attachment Disorder of Infancy," is described and is found almost universally in failure to thrive without organic cause babies. The diagnosis of Reactive Attachment Disorder is preferable because it leads to appropriate preventive and interventive action.
