What are the signs of autism?
The timing and severity of autism’s early signs vary widely. Some infants show hints in their first months. In others, symptoms become obvious as late as age 2 or 3.
Not all children with autism show all the signs. Many children who don’t have autism show a few. That’s why professional evaluation is crucial.
The following "red flags" may indicate your child is at risk for an autism spectrum disorder. If your child exhibits any of the following, please don’t delay in asking your pediatrician or family doctor for an evaluation:

Few or no big smiles or other warm, joyful and engaging expressions.
