The National Institute on Deafness and Other Communication Disorders presents age-related guidelines that can help you determine if your child’s speech and language skills are developing on schedule.
Children vary in their development of speech and language. There is, however, a natural progression or “timetable” for mastery of these skills for each language.
The milestones below are identifiable skills that can serve as a guide to normal development. Typically, simple skills need to be reached before the more complex skills can be learned. There is a general age and time when most children pass through these periods. These milestones help doctors and other health professionals determine when a child may need extra help to learn to speak or to use language.
Following are age-related guidelines that can help you determine if your child’s speech and language skills are developing on schedule. You should talk to your child’s doctor about anything that is checked “no.”
