Consider carrying a small container of ear drops that contain a pain reducer. Depending upon where you reside, you may need a doctors prescription for this.

As anyone who has ever had an earache can attest, finding any kind of relief is great until you can get better medical attention.

This is something that can be used by older folks as well and until you have experienced the crying of an infant / small child with an earache, you can't really appreciate the peace that it can provide until you can get them to the doctor.

Consult your doctor regarding the use of this for your child before needing to use it, especially if there are any medical conditions or allergies to address. Hope this helps out.
