Late-Talking Children: A Symptom or a Stage?
Stephen M. Camarata
[From article]
A child can be years behind schedule in beginning to speak and yet go on to have a perfectly normal life. Some children with delayed speech may even be noticeably brighter than other children their age. But, for other late-talking children, the delay in beginning to speak can be a symptom of much deeper and long-lasting problems, including mental retardation or autism.

False diagnoses of late-talking children are by no means rare. Even Albert Einstein was thought to be retarded, when he failed to talk at an age when most other toddlers begin to speak. Three renowned nuclear physicists who were involved in the creation of the first atomic bomb had been late-talking children.

He also explains what science knows — and does not know — about some of the possible reasons why children talk late.
