An unborn baby's hearing starts to develop early. And at birth, a baby's hearing is
fully functioning. The ability to hear is vital for correct speech and language development.
Children do respond differently at different stages of growth and development. But
hearing problems may be suspected in children who are not responding to sounds. They
may also be suspected in children who are not developing their language skills correctly.
Below are some age-related guidelines that may help to determine if your child is
having hearing problems.
It's important to remember that not every child is the same. Children reach milestones
at different ages. Talk with your child's healthcare provider if you think your child
is not hearing correctly. Here are the age-appropriate hearing milestones for most
babies and toddlers.
