Using data from 131 first-time parents with children between six and 12 months, this study applies the theory of planned behavior (Ajzen, 1991) to examine the influence parents attitudes, subjective norms, perceived behavioral control, and intentions have on the timing and introduction of complementary foods. Path analysis results indicated that parents attitudes influenced infant feeding behavior at six months old. Contrary to previous studies, additional analyses indicated parents obtain most of their infant feeding information from a doctor or other health professional and that a majority of parents are in fact introducing complementary foods at the age recommended by the American Academy of Pediatrics. Strengths and limitations of the present study are discussed, and directions for future research are presented.
