I have researched the archives and found some discussion on this topic, however, havent' been able to determine if there has ever been a proven allergy to breastmilk. A pediatrician called me today for advice as he is reluctantly thinking of recommending to a mother of a one month old to stop breastfeeding. Her baby has severe reflux being tx with medications with no improvements. Baby is gaining wgt slowly also. The baby was seen by a gastrointerologist who told him babies can have a rare allergy to the mothers milk from antibodies passed on by the baby's father. They have eliminated grains, dairy, and nuts from mom's diet supposedly, and no improvement. I suggested they try giving expressed breastmilk thickened by cereal to see if the thickness would decrease the reflux. I haven't talked to the mom but wonder if it might be overactive letdown or oversupply that could give the same symptoms. Also baby very fussy. Any advice would be helpful....how do I determine the oversupply/overactive letdown as a cause? reply to [log in to unmask] or post to list *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
