I would truly wonder about allergies this severe and this wide ranging.  I
have never heard of anyone allergic to potatoes, for example.  Are we sure
these are truly allergies?  Also, many sensitivies that babies have are long
past by 15 months.  I think that the incredibly small amounts of any protein
which might appear in the milk are unlikely to be harmful to the child.
Even true allergens taken by mouth in tiny quantities are rarely likely to
do harm, especially when they are associated with specific antibodies in the
milk.  But this many?  I would check out how the diagnosis of "allergies"
was made.  Often it is the baby took some food and choked, or had diarrhea,
or developed a rash, or was fussy after the mother ate a certain food, all
of which may have nothing to do with allergy.
