You should ask your doctor to refer your child for an audiology exam, which is a detailed hearing test in a soundproof booth. The hearing screens at the pediatrician can be worthless and can miss many hearing losses. My son has a 70 dB loss in one ear, which was missed 3 years in a row by the pediatrician. I finally asked for an audiology exam, where the loss was discovered. He now wears a hearing aid and he has done great!
