Brief Summary

Current infant feeding recommendations focus on promoting responsive feeding, which is widely recognized as the ideal way to feed infants because it is associated with healthier eating behaviors and growth outcomes for infants. Unfortunately, many bottle-feeding families receive inadequate support for learning responsive bottle-feeding practices because breastfeeding support is prioritized in healthcare settings. Promotion of breastfeeding is an important focus for public health efforts, but a significant proportion of families bottle-feed their infants, either exclusively or in combination with breastfeeding. Thus, bottle-feeding remains a ubiquitous part of infant feeding and evidence-based strategies are needed to support bottle-feeding families. One promising strategy is the Paced Bottle-Feeding (PBF) method, which incorporates many ideas and feeding practices consistent with the concept of responsive feeding. This approach to bottle-feeding aims to mimic the aspects of breastfeeding that promote balanced control between caregiver and infant and allow the infant to set the pace of the feeding in response to feelings of hunger and fullness. Although PBF is sometimes taught in perinatal education settings, teaching new parents about PBF is not an evidence-based practice because there have been no empirical studies evaluating the effectiveness of PBF for promoting responsive feeding for parents and healthy intake and weight outcomes for infants. Thus, despite the conceptual promise of PBF for promoting responsive bottle-feeding interactions, research is needed to determine whether PBF is effective and identify whether any limitations of this method exist. This study is a within-subject, experimental study wherein mother-infant dyads will be observed during breastfeeding and typical bottle-feeding interactions. Mothers will then be taught the PBF method and observed during a PBF interaction. This design will allow for direct testing of the purported benefits of PBF over typical bottle-feeding and whether PBF makes the experience of bottle-feeding more equivalent to the experience of breastfeeding. The overarching aims of this study are to explore the ways in which bottle-feeding can go well and identify mechanisms through which bottle-feeding families can be supported to promote healthy intake and weight gain trajectories for their infants.

Outcome Measures

Primary Outcomes (8)

  • Change in Infant Milk Intake between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Infant milk intake in mL, assessed by weighing the infant before and after each feeding condition

    3 visits across a 1 week period

  • Change in Meal Duration between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Duration of the observed meal in minutes (min), determined by trained video coders masked to study hypotheses

    3 visits across a 1 week period

  • Change in Rate of Feeding between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Infant milk intake divided by meal duration (mL/min)

    3 visits across a 1 week period

  • Change in Frequency of Spitting Up During and After the Meal between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Determined by trained video coders masked to study hypotheses

    3 visits across a 1 week period

  • Change in Maternal Sensitivity to Infant Cues between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Determined by video coders masked to study hypotheses and certified in the Nursing Child Assessment Caregiver-Child Interaction Feeding Scale (NCAFS); possible Maternal Sensitivity to Infant Cues scores range from 0-16 with higher scores representing greater maternal sensitivity to infant cues

    3 visits across a 1 week period

  • Change in Maternal Responsiveness to Infant Distress between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Determined by video coders masked to study hypotheses and certified in the Nursing Child Assessment Caregiver-Child Interaction Feeding Scale (NCAFS); possible Maternal Responsiveness to Infant Distress scores range from 0-11 with higher scores representing greater maternal responsiveness to infant distress

    3 visits across a 1 week period

  • Change in Infant Clarity of Cues between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Determined by video coders masked to study hypotheses and certified in the Nursing Child Assessment Caregiver-Child Interaction Feeding Scale (NCAFS); possible Infant Clarity of Cues scores range from 0-15 with higher scores representing greater infant clarity of cues

    3 visits across a 1 week period

  • Change in Infant Responsiveness to Caregiver between Breastfeeding, Typical Bottle-Feeding, and Paced Bottle-Feeding Conditions

    Determined by video coders masked to study hypotheses and certified in the Nursing Child Assessment Caregiver-Child Interaction Feeding Scale (NCAFS); possible Infant Responsiveness to Caregiver scores range from 0-11 with higher scores representing greater infant responsiveness to the caregiver

    3 visits across a 1 week period

Study Arms (2)

Breastfeeding First, Bottle-feeding Second, PBF Third

EXPERIMENTAL

Mother-infant dyads will visit the laboratory on three different days. During the first visit, they will be observed during breastfeeding. During the second visit, they will be observed during bottle-feeding. During the third visit, the mother will be taught the PBF approach and will be observed using it during bottle-feeding.

Behavioral: Paced Bottle-Feeding Education

Interventions

Participants will be asked to review an educational handout that outlines how to implement PBF during bottle-feeding interactions. Participants will then be asked to watch a video that further describes PBF and illustrates how to implement it with a live infant. A trained research assistant will then answer questions, further explain PBF, and demonstrate PBF with a baby doll, using a standardized script
