I sort of touched on this one in another post.

Assuming that a cows milk allergic or intolerant person (we're not all
children!) will be allergic/intolerant to another mammals milk is
actually pretty daft is you look at it.  Its perfectly possibly they
could be, so it should be approached with caution, but its by no means a
foregone conclusion.  Like I said earlier, its probably best to leave
challenges til children are older, but if it matters, try it.

Look at it this way.  Mammals all produce milk.  We are mammals too.  We
are all (humans, goats, sheep, reindeer, cows) just animals that produce
milk in mammary glands to suckle our young.  Just some of us got up and
walked on two legs and learnt to talk and then decided to start using
the other mammals milk.  Your child wasn't allergic to breast milk, it
was allergic to cows milk.  OK.  You've got a 50% success rate there
(the odds are slightly skewed, breast milk is designed for humans, cows
milk for cows).  On current data, its even odds whether you child is
allergic to mammilian milk.  Now if they react to goats milk, your odds
for them reacting to mammilian milk are now 2 to 1.  At that point I'd
stop.  Wait 10 years.  Try again with another variety.

I'm can't seem to get this clear here, but basically what I am saying,
being allergic to one mammals milk is no proof of being allergic to
anothers.  After all, we are pretty much *all* not allergic to at least
one variety of mammalian milk.
