Introduction
While ASD can be detected as early as 18 months or younger, diagnosis is considered very reliable by the age of 2 (Lord et al, 2006). However, many children fail to receive a diagnosis until much later, which may prevent them from getting the help they need right away.

What Can Parents Do?
As a parent, you know your child and can spot warning signs of autism early on.
- Monitor the development of your child. Keep an eye on how your child is developing socially, emotionally, and cognitively. While developmental delays do not equate to autism, they can indicate a risk.
- If you are concerned, take actions. If you have any concerns or have questions, talk to your doctor right away.
- Trust your instincts.
