  Purpose
This study will compare 2 currently marketed formulas in healthy full term babies: Nutramigen A+ (a hypoallergenic formula) and Nutramigen-Enflora (hypoallergenic formula with Lactobacillus GG (LGG)) during 3 months of formula feeding. The investigators' aims are to compare 3 outcomes in these babies: (1) normal baby crying time; (2) the composition of intestinal microbiota (bacteria in the stool); and (3) a lab test which measures the number of white blood cells in the large intestine (fecal calprotectin). The investigators predict that LGG supplementation (Nutramigen-Enflora) will facilitate its establishment as an important component of the neonatal intestinal microbial community and reduce fecal calprotectin.

Primary Outcome Measures:
  • Daily Average Crying and Fussing Duration According to Barr Diary Records [ Time Frame: 90 days ]
    The parent or guardian will complete a Barr diary to measure crying and fussing times of colicky infants . It is a daily timeline that records the number of minutes in five minute increments with fussiness and crying. The average colicky infant cries and fusses is more than 3 hours daily. If infants surpasses the 3 hours for more than three days (not consecutive) and are less than 3 months of age, they are considered to have colic.


Secondary Outcome Measures:
  • Fecal Microbiota [ Time Frame: 90 days ]
    Analyze and identify bacteria in the stool of the subjects. We will use pyrosequencing to characterize the bacteria colonizing the stool. We will measure diversity by Shannon's diversity index in the two groups.

  • Fecal Calprotectin [ Time Frame: 90 days ]
    Test intestinal inflammation in the infants. Calprotectin is made by white blood cells called neutrophils. The number of neutrophils in the intestine is reflected by the fecal calprotectin level.
