While milk does seem to be implicated in some ear infections, some seem
to be inevitable, at least if the child inherits an unfortunate inner
ear shape that makes them more prone to them.  My milk-allergic son
has already had 2 ear infections (he's 8 months old) and his couldn't
have been caused by milk.  But my husband and I and his older brother
all had lots of them as well, so we know he is probably genetically
pre-disposed to them.
