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.

- Barr Diary [ Time Frame: 2 years ] [ Designated as safety issue: No ]This will measure crying times of infants. It is a daily timeline that records the number of minutes with fussiness and crying. Normal is less than 3 hours of crying + fussing time daily.
- Fecal Microbiota [ Time Frame: 2 years ] [ Designated as safety issue: No ]Analyze and identify bacteria in the stool of the subjects. We will use pyrosequencing to characterize the bacteria colonizing the stool. We will measure if the probiotic is retained 3 months after stopping the Lactobacillus GG-containing formula.
- Fecal calprotectin [ Time Frame: 2 years ] [ Designated as safety issue: No ]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.
