Clinical Trial Summary

This study will help researchers learn more about how babies respond to bottle nipples with larger or smaller holes. Researchers guess that infants of mothers with obesity who did not lose weight prior to pregnancy will have the greatest Suck Effect on the challenging compared with the typical nipple.

Description:

The researchers will recruit babies from the original cohort in the PLAN study (NCT03244722), regardless of which arms they participated in. However, the researchers will test the study arms from the original PLAN study for effects on the study's dependent variables. Their between-subjects arms included Pre-pregnancy obesity with intensive weight loss intervention, pre-pregnancy obesity with standard of care intervention, and pre-pregnancy healthy weight with no intervention. So, although the researchers are not assigning babies to any arms, their original assignment will still be assessed the study analysis.

• Mother participated in PLAN study during child's gestation
• Infant birth weight (From PLAN study records) appropriate (= 3rd percentile and = 97th percentile) for gestational age and sex based on US Natality Data set (Oken et al, BMC Pediatrics 2003).

Intervention

Behavioral:
• Typical Nipple
Infants are fed their typical milk/formula by their caregiver when hungry, one feeding with their typical nipple.
• Challenging Nipple
Infants are fed with a smaller sized nipple (i.e. with a smaller aperture, slowing the rate of milk delivery).
