according to Riordan/ Aerbach 2nd ed. pg 519..."some women fear that bf bf will cause sufficient bone loss to place them at risk for developing osteoporosis later in life.  These fears are unfounded.  In fact, the opposite is true: bone density is restored after weaning, although the mother suffers slight bone loss while she is lactating."  pg 520 "Outcomes of bone loss studies during lactation are consistant and favor bf.  Spekers et al. (1991) compared 26 lactating women with 32 non lactating postpartem controls over the first year postpartem.  Lactating women were more likely to mobilize bone during lactation and to recover bone mass during and after weaning , weather taht occurred before or after 6 months.  Additionally, parous women who bf all their children were at lower risk for hip fracture than were parous women who had never bf their children."

hope this helps!!!:)
