My daughter has just been diagnosed with profound hearing loss in both ears, which obviously came as a shock to my wife and me. She passed her newborn screening and her one year screening, but we have always known something was wrong. She never responded to her name or reacted to loud noises, but when we told our pediatrician this he kept saying that some children just choose not to respond and that if she passed her screenings, there probably wasn't any issues with her hearing. But finally at 16 months we pushed the matter and got him to refer us to an audiologist, and the ABR showed profound hearing loss. She hasn't had any major illnesses and the pregancy and labor went fine. We're baffled as to how is happened and cannot find any examples of this. Any thoughts?
