Because young infants are so limited in their range of behavior. autistic disorders are generally discovered gradually, and rarely diagnosed before the age of two or three. Parents may not realize that their baby's behavior is different from that of other infants until he or she reaches an age where a wide range of behaviors are typically displayed. Most doctors may attempt to reassure concerned parents of infants under two years that their children are "normal," or will "grow out of" a disturbing behavior, because many children do. At the time that speech and language usually develop, parents are more likely to observe that their autistic child is not at the same level as other children his age. Once the child is old enough to play with other children, it becomes more apparent that the autistic child either isn't interested in doing so, or does so in strange, unusual ways that differ from most children of the same age.
