In the present study, we tested a novel approach to understanding infant bottle-feeding interactions: experimentally manipulating bottle-feeding conditions to better understand maternal and infant influences on overfeeding, as well as individual differences in risk for overfeeding. Specifically, we observed mother-infant dyads during a typical, "mother-led" feeding, during which mothers were given no instruction regarding how or how much to feed their infants (hereafter referred to as a "typical feeding" \[TF\]), as well as during an "infant-led" (IL) feeding, wherein we minimized the mothers' influence on the feeding and ensured the feed was in response to the infants' hunger and fullness cues. Using this within-subject, objective, and experimental approach, the present study aimed to: 1) directly measure the extent to which overfeeding occurs during bottle-feeding and 2) describe the characteristics of infants and mothers that overfeed during bottle-feeding.
