It's two in the morning, and like most people you're fast asleep. But then your eyes pop open and your three year old is standing¹ there, tugging² her ear and saying, "Mommy, my ear hurts."   

If you're a parent with a young child, this scenario³ is probably nothing new. In fact, the typical toddler averages about four ear aches per year. But when's the last time you had an ear infection? Clearly, little kids are much more likely to get an ear infection than adults. What makes kids so susceptible⁴?

Most infections happen in the middle ear, a pocket about the size of a small grape located just behind the eardrum. When kids get a cold, the auditory tube--a shaft⁵ running from the middle ear to the throat--can become filled with fluid. For grownups this usually isn't a problem, since adult tubes are large enough to let the fluid drain away. But in children under three the auditory tube is a lot smaller and more likely to get clogged⁶ up. Bacteria love this sort of clogging⁷, and soon they move in and cause infection. The ear reacts by making pus, a thick liquid that fights bacteria. As the pus builds up it pushes on the eardrum, causing pain.

Fortunately, the cure is pretty straightforward⁸. A good dose of antibiotics⁹ and your child will be good as new in a few days.

So if what seems like a constant series of ear infections is wearing you and your child out, take heart. Around when most kids turn three, their auditory tubes become large enough to make infection less likely.
