Model Details: The feeding patterns of eighty eligible infants (8 to 12 weeks in age) will be characterized based on a 7-day diet record that will be filled out by their mothers during the 7-day lead-in period starting with Day -7 and ending with Day -1. Of the eighty infants, twenty will be exclusive breast feeders (BF), twenty will be exclusive formula feeders (FF) and forty will be mixed-feeders (MF). Infants in all three feeding groups will consume B. infantis for twenty-one consecutive days. Participants will then enter the observational phase until their infant turns 1 year old.
