About this speech delay guide: A complete, practical speech delay guide for parents and teachers of babies, toddlers and preschoolers: signs and milestones by age, late talkers, speech delay vs autism, early intervention, speech therapy at home, gestalt language processing, screen time, bilingual children, hyperlexia, stuttering and articulation. Each article includes tables, diagrams, scripts and real-life examples.
What This Speech Delay Guide Covers
Between 10% and 20% of 2-year-olds are late to talk, according to the American Speech-Language-Hearing Association. Many catch up, but no one can predict which children will. This speech delay guide helps families recognize signs early, get a free evaluation and use proven strategies every day. In the United States, early intervention under IDEA Part C serves children from birth to 3, and preschool special education takes over at age 3.
How to Use This Speech Delay Guide
Start with the signs and milestones articles to see where your child is. If you are worried, read about early intervention and speech evaluations, then use the home activities while you wait for services. The later articles answer specific questions about autism, screens, two languages, early reading, stuttering and speech sounds.
