Tell your child’s doctor or nurse if you notice any of these signs of possible developmental delay for this age and ask for a developmental screening. Talk with someone in your community who is familiar with services for young children in your area, such as your state’s public early intervention program. For more information, visit our “If You’re Concerned” web page or call 1-800-CDC-INFO.
The American Academy of Pediatrics recommends that children be screened for general development using standardized, validated tools at 9, 18, and 30 months and for autism at 18 and 24 months or whenever a parent or provider has a concern. Ask your child’s doctor about your child’s developmental screening.
