The following may be signs of developmental delay. There is a wide range of typical development. However, follow up with a pediatrician if your child shows signs of delays.

Remember, though, that most delays are not serious. Most children eventually catch up. Even children with serious delays can make big improvements when treatment begins as early as possible. Treatment may include early intervention with a specialist, including play, behavioral, and skill-oriented therapy. Intervention may also include socializing with adults and peers.
