Parents know their children. We recommend that parents always act on their concerns. If you are concerned, talk to your child’s doctor. You also can contact your local early intervention agency to request an evaluation of eligibility for early intervention services for your child. If you are in the US you can find your state’s intervention office here: https://www.autismspeaks.org/resource-guide If you are not in the US, you should be able to find out what kind of early intervention services are available in your region. Some additional information about early intervention in other countries can be found here: https://www.autismspeaks.org/international-autism-organizations
