im sure this is probably nothing (or we'd have called the ped.) but my 10 month old has been covering his ears a lot today. Not linked to any particularly loud or new sounds, just all of a sudden lifting his hands or arms over his ears for a few seconds. Thinking probably just teething pain? or some wax in there? Or just a fun new thing he stumbled upon? No other symptoms so I'm not too worried about ear infection, but just curious if anyone has thoughts?
