7 Common Signs of Autism in 18 Month Old Children

Spotting autism in 18-month-olds early is key for help. At this age, kids should hit certain milestones. Not reaching these can hint at autism spectrum disorder (ASD). We’ll look at signs that might show autism in 18-month-olds.

Most 18-month-olds start saying a few words and simple sentences. Kids with autism might talk much later. They might not babble, try to talk, or answer when called.
