AHH boomers, at least he won't be sticking his head to fridge anytime soon then/
They do the implants for people over a certain db loss, but it's not just total deafness. According to my wife it's about 70db of hearing loss before you're considered for implants as an adult, and 60-80 for children depending on where on the scale it is. Steff also says that UNC is the best in the state for aids/implants.
Good for you to get him aids early. The earlier a kid gets his hearing the better he does in school and languages, it really does make a huge difference.
Hang in there, it'll get better and he's in good hands.
