Being proactive about the diagnosis using evidence-based tools; MCHAT will improve early diagnosis. This is especially important as early diagnosis with early intervention can make a huge difference in outcome with a few to maximizing the chances of the independent living and minimizing functional impairment.

In brief: Possible
It is possible for symptoms of an autistic spectrum disorder to not be noticed until after 3 years of age.
Officially, symptoms must be present by 3 years of age to make the diagnosis. However, in reality, in everyday practice, children are often not brought to the attention of a professional for evaluation until after 3 years of age.

The distinction is important, though: except for a rare condition called childhood disintegrative disorder, autism symptoms nearly always are present before age 2 1/2-3, even if the diagnosis is not made till much later. We believe that this is a problem of early development, no something one "catches" later in life.

In brief: Unlikely
The symptoms of autism are usually present before age 2.
However, if you are seeing something that concerns you, i would still consult with your child's doctor.
