简要总结
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.
详细描述
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.

盲法说明
Order of nipple size use is counter-balanced, caregivers are blind to nipple size and amount of milk in the bottle (i.e., the bottle is covered) to minimize their influence over the infant's consumption. Research assistants will not be blind to nipple size as they will need to set the bottles ups for the mothers.
