Children develop language skills at different rates, but many start to form sentences around 2 years of age. By 4 years, most children can speak in fuller sentences and have a vocabulary of several hundred words. Fluency continues to improve through practice and social interactions.
At around 4 years old, your son may begin to:
- Speak in longer sentences (3-5 words or more).
- Use more complex grammar.
- Tell simple stories or describe
