Dyslexia is a learning disorder that affects both children and adults. Its symptoms are different with age, and severity can vary as well. Generally, people with dyslexia have difficulty breaking down words into simple sounds.
Baby talk at 2 years. By 18-24 months, a child will be able to use 50 or more single words and start to put together short sentences, such as âbye Daddyâ. They're learning that words mean more than objects such as cup - they also mean abstract ideas such as 'mine'.
At 18 months, children typically use around 50 (but we don't worry too much unless they have fewer than 10-20). At 24 months, children usually have an expressive vocabulary of 200-300 words (but we don't worry too much unless they have fewer than 50). At 3 years, children can have anywhere from 500-1,100 words in their vocabulary. By 5-7 years, children have an expressive vocabulary of 3000-5000 words.
