  Purpose

There is a paucity of information on whether and how the composition of formulas fed to infants influences their short-term feeding behaviors during the first few months of life. The purpose of this study is to investigate whether the composition of infant formula affects infants' feeding behaviors, in particular, how much formula is consumed within a given feed (i.e., measure of satiation) and how much time elapses after the feed until the infant exhibits signs of hunger (i.e., measure of satiety). The investigators will also examine the relationship between the composition of infant formula consumed and infant temperature, activity, sleep, and mothers' perceptions of infants' intake and regulatory behaviors.

Primary Outcome Measures:
  • Satiation: volume of formula consumed within a feed [ Time Frame: 5-hour period ] [ Designated as safety issue: No ]
  • Satiety: the duration between feedings [ Time Frame: 5-hour period ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Infant temperature change [ Time Frame: 5-hour period ] [ Designated as safety issue: No ]
  • Infant sleep and activity patterns [ Time Frame: 5-hour period ] [ Designated as safety issue: No ]
  • Maternal perceptions [ Time Frame: 5-hour period ] [ Designated as safety issue: No ]

Detailed Description:

This is a within-subject, 3-day study. Each mother-infant dyad will visit the Monell Center three times, for 5 hours each time. The protocol during the three visits will be identical. Upon arrival, the infant will be changed into a light-weight cotton body suit. Infants and mothers will be weighed and measured for height. An activity sensor will be placed on the infant and temperature sensors will be placed on both the infant and the mother. When the infant signals hunger, he/she will be fed one of three formulas in randomized order:

  1. cow milk based-formula (Enfamil)
  2. protein hydrolysate formula (Nutramigen)
  3. cow milk-based formula with glutamate level similar to Nutramigen (Enfamilg)

Intake will be monitored and all feeds will be videotaped. In between feedings, infants will rest or sleep on their backs in a crib and mothers will fill out questionnaires.
