The purpose of this study is to pilot test whether a novel infant feeding bottle changes how much formula an infant drinks and how quickly he/she drinks it, as compared to meals provided in a standard bottle. Exclusively formula-fed infants and their caregiver will be provided with the novel feeding bottle and caregivers will be asked to acclimate their infant to this bottle during the next several weeks. Once acclimated, infants will undergo two weighed, timed, and videotaped test meals on two separate days; one with the novel bottle and one with their standard bottle, in random order. It is hypothesized that when the novel bottle is used, infants bottle will consume smaller meals and will have a longer meal duration, as compared to when a standard bottle is used.
