The timing and severity of autism’s first symptoms can vary widely. Some children with autism show hints of future problems within the first few months of life. In others, symptoms may not become obvious until 24 months or later. Some children with autism appear to develop normally until around 18 to 24 months of age and then stop gaining new skills and/or start losing skills.
The following "red flags" suggest a child is at risk for autism. Some children without autism have some of these symptoms. That’s why further evaluation is crucial. If your child exhibits any of the following, please see Step 2: Get your child screened.
