If your 2-year-old daughter is complaining of ear pain and tends to have frequent ear infections, there are a few solutions you can try. One option is to use Polysporin™ ear drops to see if it helps improve her symptoms. If that doesn't work, it's best to consult a doctor. In the future, you can also prepare a mixture of vinegar and warm water to put a few drops in her ears each time she comes out of the pool to help prevent swimmer's ear infections.
