I've only taken a child to the doctor for an ear infection once. When Logan was a year old (plus or minus some months) I asked the dr. to take a look at his ears because he was unusually cranky and had been playing with his ear. The dr. looked at me and said something very similar to, "You just have a cranky baby." When I re-mentioned the ear-touching he said something like, "He is discovering something fun and flappy on his body."
For this reason I have never taken a child to the dr. for displaying ear-infection symptoms (and I wait until I know they are really sick to take them in for any other reason, as well). Good thing our dr. friends have told us just to give babies tylenol and wait the ear infection out. So far it has worked.
Today Ammon is unusually cranky and he keeps tugging on his ears.
