The Impact of Pre-Pregnancy Weight Loss on Infant Sucking Behavior in Response to a Challenging Nipple.

A clinical trial, NCT06358729, is currently underway to examine how pre-pregnancy weight loss affects infant sucking behavior in response to different nipple sizes. The study aims to recruit babies from a previous study and evaluate the effects of various interventions on the dependent variables. Specifically, the researchers are interested in understanding how infants, particularly those born to mothers with obesity who did not lose weight before pregnancy, respond to bottle nipples with larger or smaller holes. The trial is interventional, with a randomized allocation, and its primary purpose is basic science. The study plans to enroll 30 participants and is expected to conclude by April 2027. Infants aged 3 months and older who consume at least 2 ounces of milk from a bottle with an artificial nipple once a week are eligible to participate. The study will compare two different orders of nipple use and assess their impact on milk delivery rate.
