Babies learn from the time they are born. One of the ways they learn is through hearing. If they have problems with hearing and do not receive the right treatment and early intervention services, babies will have trouble with speech and language development.
For some babies, early intervention services may include the use of sign language and/or hearing aids
Some parents think they would be able to tell if their baby could not hear. This is not always the case. Babies may respond to noise by startling or turning their heads toward the sound. This does not mean they have normal hearing. Most babies with hearing loss can hear some sounds but still not hear enough to develop full speaking ability.
Timing is everything. Your baby will have the best chance for normal language development if any hearing loss is discovered and treatment begins by the age of 6 months—and the earlier, the better.
