It might have something to do with the Eustachian Tube. In children under the age of seven it is shorter and in a more horizontal position than adults. Because of this, mucus might not drain from it as efficiently as it drains from adult ears, thus upping the chance of an ear infection.

The Short Answer

It might have something to do with the Eustachian Tube. In children under the age of seven it is shorter and in a more horizontal position than adults. Because of this, mucus might not drain from it as efficiently as it drains from adult ears, thus upping the chance of an ear infection. Other people feel it has nothing to do with the Eustachian tube, but just has something do with the immune system which is still under developed and not as capable of fighting off these infections. AKA science ain't 100% sure yet.
