Brief Summary:
The purpose of this study is to investigate the dose of a probiotic supplement (Bifidobacterium longum subsp. infantis) required to achieve predominant gut colonization in healthy newborn, breastfed infants. The study will also examine whether supplementation with this probiotic can reduce the chance of developing eczema and food allergies in enrolled infants.

Arm Intervention/treatment
Experimental: B.infantis
Infants in the experimental arm will have two doses of the probiotic Bifidobacterium longum subsp. infantis (B. infantis) on Day 7 and Day 14 of life.
Drug: B. infantis
Infants in the intervention group will receive two doses of B. infantis on Day 7 and Day 14 of life, while infants in the placebo group will be dosed with placebo on Day 7 and Day 14
Other Name: Probiotic

Placebo Comparator: Placebo
Infants in the experimental arm will have two doses of placebo (powdered maltodextrin) on Day 7 and Day 14 of life.
Drug: Placebo



Primary Outcome Measures :
  1. Pharmacologically effective dose (ED) of B. infantis [ Time Frame: Two years ]
    The primary endpoint of the study is identification of a pharmacologically effective dose of B. infantis required to produce predominant (>50%) gut colonization at six weeks of age

  2. Safety of Probiotic Supplementation, as assessed by frequency of adverse events [ Time Frame: 2 years ]
    An additional primary endpoint is to determine the safety of B. infantis supplementation in immunocompetent, full-term infants. Any adverse events including fever 102°F or higher, abdominal pain or colic, blood or pus in the stool, diarrhea or vomiting will be documented and dosing adjusted accordingly


Secondary Outcome Measures :
  1. Milk Oligosaccharide Consumption [ Time Frame: 2 years ]
    All stool samples will also be analyzed for the presence of oligosaccharides unique to breast milk and for the presence of free saccharide monomers, which are products of their incomplete digestion. B. infantis abundance will be correlated to these values.

  2. Stool Microbiota Composition [ Time Frame: 2 years ]
    In addition to determining the percent composition of B. infantis in infant stool samples, numerous other measures such as microbiota diversity and rate of B. infantis decline following cessation of breast feeding will also be determined.
