Age-Appropriate Speech and Language Milestones

---

While not every child develops speech and language on the same timetable, the National Institute on Deafness and Other Communication Disorders does provide a list of age-appropriate speech and language milestones for babies and young children.

If you suspect your child is failing behind his peers, consult your child’s doctor or schedule a speech and language evaluation for your child.
