What are signs of autism in a 21 month old?

Answer by  Steph (16)

One autistic person's symptoms can be very different from another autistic person's symptoms. However, common symptoms of autism include delayed or unusual speech patterns, high pitched or flat intonation, difficulty understanding tone of voice or body language, lack of eye contact, or inability to take another's perspective.

Autism is very difficult to diagnose in children under 3, but early symptoms may include poor language and motor skills, inability to play social games, and poor emotional expression.

There are too many variables to be certain. Ask your pediatrician for a referral to a neuro-pediatric specialist. Not speaking or very little speech, poor eye contact, unusual movements.
