Breast Post- Difference Subject Feeding Weaning = P – B Breast feeding sometimes results in a temporary loss of bone mass as calcium is depleted in the mother's body to provide for milk production. A study by Bezerra et. al in 2004 used a sample of 10 adolescent mothers aged 15-18 who habitually consumed < 500 mg Ca per day, and measure their total body bone mineral content (TBBMC, in grams) both during breast feeding and in the postweaning period".
