This federal government website contains educational information about language & speech disorders and their comorbidity with developmental disabilities and mental health conditions.
Children are born ready to learn a language, but they need to learn the language or languages that their family and environment use. Learning a language takes time, and children vary in how quickly they master milestones in language and speech development. Typically developing children may have trouble with some sounds, words, and sentences while they are learning. However, most children can use language easily around 5 years of age.
