S.T.
my kids were the same way. multiple sets of tubes, tonsils and adenoids removed, but they kept getting ear infections.
maybe the tubes helped. i dunno. they've both got some scarring in their inner ears but had they got even more infections and ruptures they'd have ended up with scarring too.
i think trying a chiro is a good idea. i know several moms in our homeschool group who swore by it for their kids with crappy ears.
