If your notice any of these issues, give your pediatrician a call, since the earlier hearing loss is diagnosed, the more likely treatments like hearing aids, speech therapy, and cochlear implants (surgically implanted devices that provide a sense of sound) will help prevent speech and language delays. In fact, one study found that children whose hearing loss was detected by 6 months had normal language skills by age 3, while children who were diagnosed later were more likely to be behind. --Julie Evans
