Slow-Flow nipples may curb overeating in infants
NCT ID NCT07665983
First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 2 times
Summary
This study tests whether using a slower-flow bottle nipple for a few days helps babies drink less milk and develop healthier feeding patterns. Researchers will monitor 440 infants to see if the change affects how much they eat, their sucking behavior, and sleep. The goal is to find a simple way to prevent overfeeding and reduce the risk of childhood obesity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- slower-flow bottle nipple
- What this could lead to
- If this works, it could point toward a simple, low-cost way to help babies learn healthy eating habits and reduce the risk of childhood obesity.
- What could go wrong
- This is an early behavioral study, not a treatment. Results may not apply to all babies, and the effect on long-term weight is uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Mother-infant dyad: The biological mother is the legal guardian of the infant and has custody for ≥5 days per week (in cases of joint custody). 2. Maternal age: Mother is ≥18 years old. 3. Language: Mother understands spoken and written English sufficiently to provide informed consent, answer questionnaires and follow study instructions. 4. Gestational age: Infant was born at 37.0-42.0 weeks gestation. 5. Birthweight: Infant's birthweight was appropriate for gestational age. 6. Bottle feeding: Infant currently receives at least one bottle feeding of ≥2 ounces at least once per week. 7. Residence: Family lives within approximately one hours driving distance of Ann Arbor, Michigan to participate in an at- home appointment or is willing to drive to the U-M North Campus research site. 8. Infant age: Infant is 4.0-6.0 months old at enrollment. Exclusion Criteria: 1. Current maternal depression or anxiety, as assessed by screening questionnaires, or any cognitive impairment that would limit ability to follow study instructions. 2. Infant developmental delay, genetic condition, or medical problems or diagnosis affecting current or future eating, growth, or development. 3. History of significant sucking or feeding difficulties or breastfeeding difficulties requiring significant medical intervention or support. 4. Current weight-for-age below the 10th percentile or significant history of poor weight gain. 5. Infant already typically uses a slower-flow nipple (flow rate \< 5 mL/min).
