If your baby shows any of these signs, please ask your pediatrician or family practitioner for an immediate evaluation:
  
•No big smiles or other warm, joyful expressions by six months or thereafter
•No back-and-forth sharing of sounds, smiles, or other facial expressions by nine months or thereafter
•No babbling by 12 months
•No back-and-forth gestures, such as pointing, showing, reaching, or waving by 12 months
•No words by 16 months
•No two-word meaningful phrases (without imitating or repeating) by 24 months
•Any loss of speech or babbling or social skills at any age

Scientists estimate that, in families with one autistic child, the risk of having a second child with the disorder is approximately five percent, or one in 20, which is greater than the risk for the general population.

About half of people with autism score below 50 on IQ tests, 20 percent score between 50 and 70, and 30 percent score higher than 70. However, estimating IQ in young children with autism is often difficult because problems with language and behavior can interfere with testing. A small percentage of people with autism are savants. These people have limited but extraordinary skills in areas like music, mathematics, drawing, or visualization.
