Talking is an important milestone in children’s development.
Most children will know how to say 100 words by the age of 21 months and will start to combine these words into short sentences before they are 2 years old. Unfortunately many young children fall behind these milestones.
Children who have limited expressive vocabulary (less than 40-50 words) at 24 months and make no word combination are identified as “late talkers.” About 8-12% percent of North American preschool children and 12% of children beginning school have language delay. Of these, 25-90% are diagnosed with a reading disorder – a problem that goes on to affect 10-18% of all school-age children.
The frequency of language problems and its impact on literacy and reading later in life speaks to the need for early intervention as soon as speech problems are detected.
