KempsMama, it's actually pretty unusual for babies to have issues with lactose. Human milk has 5 times more lactose in it than cow's milk. Babies can have a sort of temporatry lactose intolerance due to too much foremilk hitting the gut all at once without any fat to balance it out, but that's neither an allergy nor a true intolerance.
There's a difference between a true cow's milk protein allergy and a cow's milk protein intolerance/sensitivity. The latter is more of a physical issue. Cow's milk proteins are of a physical size that they can pass through a baby's leaky gut virtually undigested, but they don't go easily and their forcing their way through can cause tiny GI bleeds in some infants. They're too small to be held back, but too big to go through without trauma and they manage to reach the blood un-sufficiently broken down which can cause an immune response.
Things like yogurt and cheese have proteins that have already been partially digested, so they're not really in the same category as whole, pasteurized milk.
