Hi J.,
I see a wonderful chiropracter who has also worked on my duaghter several times now (my daughter will be 2 in May).
Her name is Dr. Linda Squires out of Amythest Chiropractic in Somerville (Davis Square). She is very gentle and uses non-force technique.
Also, have you checked out his diet? Sometimes recurrent ear infections can be due to allergies. Common culprits include wheat (bread or any bread product) and dairy.
If your little guy has been on a few rounds of antibiotics, you may want to consider giving acidophilous (the good bacteria, it is what makes yogurt so good for your digestive tract, but without the dairy). I mix about 1/4 teaspoon (powder) in a small amount of water and my daughter eagerly drinks hers daily! Also supposed to help with immune function...
Good Luck!
E.
