My dayghter has had a small hole inside of her ear since she was an infant. It is not visible to everyone. I noticed it one day as i was cleaning her ears, when I lifted the little fold at the fron of her ear I saw it. She has never complained of any pain, about once every month or two i have to wait for her to go to sleep and then clean it. I think that the hole collects dirt(i guess) so I clean it to prevent any type of health problems. Should I be worried, is it an indicater of another problem ?
