When my daughter (4 years old, now) gets congested from a cold, she sometimes ends up with an ear infection. But she never complains about her ears bothering her until it gets really bad so, by time we bring her to a doctor, she has a "nasty bulging infection" (doctor's words).
I would like to check routinely throughout a cold to see if infection is setting in. I look in her ear and it looks pretty much... like an ear. Does anybody know any home-grown techniques for checking for an ear infection? I'm sure doctor-dad could improvise (or buy) an otoscope but would I see anything I recognize?
