Keitha:  I've never seen any literature specifically stating that bf has
particular benefits to mothers with seizure disorders.  However, it's fair
to assume that this mother has not seen any really convincing evidence
of the overall importance of bf to both her baby's health and her own, so
providing her with a copy of some real good literature to counter the
usual "bf is probably better for the baby but formula is about as good"
would probably help.  Also, since fatigue is commonly a trigger for
seizures, the relaxing aspects of nursing, e.g. prolactin-induced
relaxation, ease of night nursings (especially if she's amenable to
co-sleeping), and general convenience of not having to prepare bottles,
etc, might all appeal to her.
To help her with her doctor's recommendation, it's important to get more
information.  Is the doctor concerned about her having a seizure while
nursing? (If so, there is no greater danger to the baby if the mother has
a seizure while bf than while bottle-feeding).  Is he/she concerned about
the potential effects of anticonvulsant meds through the milk? (If so,
then providing info re AAP compatible anticonvulsants would help).  Is
he/she just one of the many docs who are ignorant of the importance of bf
and not willing to bother educating themselves on this issue?  (She may
want to get a second opinion).  Hope this helps.  Alicia Dermer, MD,
