Why would anyone think of doing this? If the baby is allergic to cow's milk
then he's already been exposed to mom's diet and the milk. If you pump and
dump during the elimination process what will you feed the baby? A formula
based on cow's milk? A formula based on soy? (about 50% of the babies
allergic to cow's milk are allergic to soy). If you pump and dump you will
have the baby miss out on all the other "good stuff" obtained from breast
milk. Unless baby is having severe allergic symptoms (anaphylactic shock for
instance) I can't imagine depriving him of his mother's milk.
Usually the symptoms observed are flat red rash and/or colic-like symptoms.
As mother decreases her milk intake (and cheese, yogurt, whey, casein) you
will gradually see an improvement in baby. This helps with the diagnosis
