“…Although all infants with FTT have a serious underlying medical/organic problem (i.e., undernutrition), many clinicians and researchers still refer to FTT as either 'organic' (when an underlying medical problem causally linked to the undernutrition is present) or 'nonorganic' (when no underlying medical problem, other than undernutrition, is present). Many 'nonorganic' factors have been implicated as etiological contributors to FTT (Drotar, 1985;Benoit, 1993a). The most common is that FTT is a sign of deficient parental care and a disturbed relationship between infant and caregiver (Barbero & Shaheen, 1967;Berkowitz & Senter, 1987;Chatoor, Egan, Getson, Menvielle, & O'Donnell, 1987;Shapiro, Fraiberg, & Adelson, 1976;Stanhope, Wilks, & Hamill, 1994;Wright, Waterston, & Aynsley-Green, 1994).…”
