EARLY CHILDHOOD INTERVENTION
Between the ages of 2 and 5 years, children demonstrate the greatest growth in speech and language development. There is much variability in language development but most two years olds are able to put 2 words together to form simple sentences. Between 2 and 3 years of age, children add about 450 words to their vocabulary and significantly increase their sentence length and complexity.
Vocabulary grows by between 1000 to 1500 words between the ages of 3 and 5 years and children add more complex sentence structures, understand past versus present tense, understand concepts such as colour, shape and size, and can retell stories and events. Most estimates suggest that approximately 10 percent of preschool children have some speech and/or language delay.
Studies show that early intervention is important for maximizing development and minimizing the effect of speech and language delay on later performance and achievement.
