What are the Signs of Autism?

It is important to know what typically developing milestones are for your child, as well as learn the signs of autism spectrum disorder. This will allow you to keep a close eye on your child and know if it is time to conduct a developmental screening or seek an evaluation.

Not all children with autism show all the signs and many children who don’t have autism show a few. The following ‘red flags’ may indicate that your child is at risk for an autism spectrum disorder.

By 6 months Few or no big smiles or other warm, joyful and engaging facial expressions

Limited or no eye contact

Little or no back-and-forth sharing of sounds, smiles, or other facial expressions

Little or no back and forth gestures such as pointing, showing, reaching, or waving

Little or no response to name
