The information provided on this site is for educational purposes only. It is not intended to – nor SHOULD it – be used to screen or otherwise evaluate your child for speech, language, or social communication delays. It is not a complete inventory of typical child language development and does not take into consideration any variables that can affect development. In addition, this information includes limited details of the development of word and sentence grammar use and understanding, which are very important to the way older children interact with others. Finally, literacy milestones are not discussed.
