Possibly, but not necessarily. About 10% of preschool children have a language delay, but only 2% of children have autism. This means that the majority of children with delayed speech do not have autism. Autism is often accompanied by other signs beyond speech delay. See this infographic for more on the signs of autism and a broader list of potential signs of autism.
If your child is not meeting common developmental milestones, you should mention this to your pediatrician or another specialized healthcare provider like Soar. Examples of common milestones by age-related to language are shown above on our website. You can also check out the CDC's website on Milestones in Action to see a complete set of videos related to developmental milestones. For those families interested in an assessment or testing for a child, you can read more about our child psychologist Dr. Wischkaemper on the Testing page or reach out to us at 720-706-3396 to schedule an appointment.
