Hi Shauna,
There ARE many remedies which address the sensitivity to milk that you describe--in fact, any one of the remedies used in homeopathy, properly applied, could address this issue in a patient. Every case has to be individualized.
That being said, nutritional "trends" change every 4 minutes: in one flash, all milk and its products are bad for everyone. In another, milk is okay and healthy. Low fat is the way to go; low fat will kill you...that inconsistency and disagreement in this field makes it very crazy. Many people who deal with nutritional therapy adopt a subjective model and apply it to everybody indescriminately, unfortunately.
That is why I would suggest being skeptical whenever someone arbitrarily declares a "milk sensitivity" (without obtaining clarification and proof of this) and orders complete abstinence of milk products "just because" its "supposed" to be just for baby cows--and not for baby humans.
The fact is, human beings have been eating milk and milk products for millenia. We see variations of the use of milk in every single culture in existence. In some cultures, fresh milk is not consumed in quantity because it seems to be too difficult for people to digest--but in these cultures we often see great consumption of milk products such as creams, yoghurt/kefirs, and cheeses. Where cow milk has been traditionally less available, other animal milks have been used--and in some cases, vegetable equivalents which can produce the same or similar nutrients as milk are used instead (eg. soy milk, which mimics human milk to a certain extent, is fermented into miso, or made into tofu, a kind of equivalent to cheese). Milk, as a food source, has been quite important to human beings for as long as humans have been around. Arbitrary decisions about milk eating--one way or the other--really have no scientific basis, in this context.
That being said, it is quite easy to tell when a patient has a sensitivity to milk in any one of its forms, or an "allergy" to one of its proteins. The reactions are very clear, in either case. Sensitivities can range from producing too much gas in digesting the milk and developing too much mucus from milk ingestion, to actually being unable to digest the milk (diarrhea and vomitting occur, often in babies and often with mother's milk, too). Allergies to milk are much more dramatic--and much more rare. Allergic reactions to milk are just the same as allergic reactions to anything else...in other words the body reacts the same way it would as in an allergy to shellfish or bee-stings--redness, swelling of tissue, pain, difficult respiration, etc.
For some really great nutrition information, based on independent research not funded by food producers or drug manufacturers, check out the Price Pottenger Foundation's website at

Incidentally, ear infections are not necessarily a product of milk ingestion--though I can see how a build up of mucus and waste products resulting from milk ingestion could force the body to start "clearing out" some debris, and start an inflammatory process to do this...anyway, it seems your homeopath took care of the problem. Have any of the infections recurred (as they do in many, many children?)
