1) To determine when the majority of male infants are being circumcised at 3 hospitals across the US (Brooke Army Medical Center, Naval Medical Center San Diego, and Dartmouth Hitchcock Medical Center. 2) To assess the breastfeeding patterns of circumcised male infants at the above-mentioned academic medical centers. Specifically, to determine if these babies are breastfeeding at the time of hospital discharge, at their newborn visit, their 2-week visit, and all subsequent well visits up until 6 months of age.

3) To determine if there is a significant relationship between the timing of newborn circumcision and breastfeeding initiation, establishment, and maintenance in the first 6 months of life. We hypothesize that the timing of circumcision will not be significantly associated with frequency of breastfeeding among mother-infant dyads during the initial months of life.
