The American Academy of Pediatrics (AAP) recommends screening for signs of autism from 18 to 24 months. However, the diagnosis of autism is only made after four to five years of age. Babies with autism can significantly delay age-appropriate social, cognitive, and skills development. They may have noticeable and repetitive movements such as knocking, rolling over, or spinning. Avoiding eye contact can also be an early sign of autism (9).
