Early Speech Development
The development of speech is a complex process that is influenced by environmental factors and genetic predispositions. Normally, by the age of 4 most children will be able to communicate effectively. Specific language impairment (SLI) is a language disorder that delays the mastery of language skills. Some children with SLI may not begin to talk until their third or fourth year. In some cases the SLI is the first sign of other conditions such as ADHD and autism.
