In brief: 12-18 months
Autism is by definition a derangement in social interaction, among other things.
Most parents may not see autism symptoms for what they are until later, and those not familiar with the child may not recognize them either. But looking back, often you can see where the signs began before 1 year of age: not making good eye contact, or looking to mom for social cues. These become more obvious by 2 y.

In brief: Debatable
Many professionals say that as early as six months of age, one can begin to see hints of autism spectrum disorders including social aversion, lack of eye contact, and other developmental delays.
Others feel it may not be identified until 4-5 years of age. Best thing is to interact actively with your child as much as possible, and if you have any concerns share them with your pediatrician.

In brief: Various ages
Autism is a "spectrum" disorder - that means there are various symptoms and varying times of onset and degrees of severeness that any particular child may show.
Some autistic kids may present even as infants - not liking to be touched or cuddled, poor response to smiling, etc. Other kids may not be noticable until they go into society - such as daycare or school. It varies alot.

In brief: May be early
Children with autism may show social withdrawal as early as the neonatal period.
During that time they may not calm when held, may not make eye contact and do not enjoy body contact. More common is the development of these features later in the first year.

In brief: Age-dependent
Social withdrawal often is not noticed till the child's typically-developing peers engage in parallel play by age 2 or interactive play by 2 1/2-3.
At 12-18 mos., not engaging at family events, exhibiting avoidance behaviors. Lack of social reciprocity can be noticed by diminished eye contact, lack of social smile, lack of interactive gooing & cooing by 2-4 mos. The pddst is a good screen.
