This study assessed the quality of caregiver-infant feeding interaction with 3- and 9-month-old infants. Findings on several measures indicated that caregivers appear to be more vigilant to their infants' needs at three months than at nine months, although infants became clearer in their cues by nine months. Maternal personality was not related to the quality of the feeding interaction at the younger age. However, the quality of interaction between mother and infant at three months was related to higher father report of negative affect at the same age. By nine months, both mother and father reports of positive affect were related to better quality interaction between mothers and their infants during feeding. Infant temperament also played a role in the feeding interaction by nine months. Less infant activity, frustration, distress to novelty and more positive affect were related to better quality interaction between infants and mothers at this older age. (JPB)
