Age-Appropriate Speech and Language Milestones

The ability to hear is essential for proper speech and language development. Hearing problems may be suspected in children who are not responding to sounds or who are not developing their language skills appropriately. The following are some age-related guidelines that may help to decide if your child is experiencing hearing problems.
 
It is important to remember that not every child is the same, and children reach milestones at different ages. Consult your child's physician if you are suspicious that your child is not developing speech and language skills correctly. The National Institute on Deafness and Other Communication Disorders (NIDCD) and other experts list the following for babies and young children.
