The molars can effect the ears. Are you giving him some infant tylenol or motrin for the pain? Another thing to help him sleep,try some hylands teething tablets. They seem to help when the teeth come in and they are cranky. They dissolve right in the mouth. DO this after you give him some teething tablets before bed. He is having teething issues is what my gut instinct tells me. The tablets are available at pathmark,walgreens,target and walmart. See if it helps. Good luck, hope he feels better soon.
