Antibiotics most of the time, do not work for ear infections. The vast majority of ear infections are viral. Antibiotics are given to make the parent feel better most of the time.
Ear infections are caused by restriction of the eustachian tube. Therefore, the natural drainage of the ear is restricted.
I would do the ear candle thing or this stuff . When I or my kids get an ear infection we go get adjusted to clear the tube and restore drainage.
