        My name is Sarah O'Connell and I am a nursing student at the
University of North Dakota College of Nursing.  I have a client who is
expecting and very anxious to breastfeed who raised the question of
exercise and breastfeeding.  I searched the archives and researched the
topic and still would appreciate your thoughts on the issue and any other
comments or questions you may have.
        Lovelady (1990) noted that exercise has little effect on milk
production.  According to Wallace (1992), his research found the milk
expressed after-exercise to be higher in lactic acid.  He also compared
the babies' acceptance of the before-exercise milk with the milk expressed
after their mothers exercised and found the babies to be less accepting of
the after-exercise milk.  One limitation of this study was the fact that
these babies were fed with medicine droppers, a new feeding method for
them.  In Dewey and McCrory's (1994) study, they found that exercise
during breastfeeding is safe for most women.
        Taking this information into consideration, I am interested to
know if anyone has noticed in their practice a great incidence of exercise
and problems with babies' acceptance of after-exercise milk or if anyone
has any new information.  It would be greatly appreciated. Thank You,
Sarah O'Connell, College of Nursing student (University of North Dakota).
