Girls, I have a question. Yesterday we found out that my son has an ear infection in one ear, I was shocked. The day before, we went for a walk for 30 minutes, while the weather allowed it. Now the doctor prescribed medicine, and there you need to wet the cotton swab and apply it to the ear, but will it definitely get better? Wouldn't it be easier to prescribe drops? If your children have had such illnesses, please share if possible.
