Perioral movements and sucking pattern during bottle feeding with a novel, experimental teat are similar to breastfeeding

Objective:to measure intraoral pressure and perioral movement in infants during breastfeeding (bf) and feeding with experimental teat (et). the teat has a wide base, firm shaft and a valve at the base, such that milk flows only when the baby provides a hold pressure.study design:twenty healthy term infants, between 1 and 8 months old, were enrolled in the study. feeding sessions (bf and et) were recorded using a digital video camera. during both bf and et feeding sessions, recordings during feeding were taken of jaw and throat movements (n=20) as well as intraoral pressure (n=18). the efficiency of milk transfer and the angle of the mouth were also measured.result:there was no significant difference in either the jaw or throat movements between bf and et. the sucking burst pattern, the efficiency (ml min−1), and the angle of the mouth did not differ between both feeding methods. the intraoral negative pressure observed during et was significantly smaller than that observed during bf.conclusion:there were no significant differences in perioral movements. although the value was smaller, a hold pressure was observed during et. from these results, the novel, et may decrease bf problems related to bottle use.
