Italianwoman,
How is the child's sleep? Look at this post. It maybe a bit old.. but it is a good one.

Younger than 5 years of age is often too young to officially diagnosis mild cases of Autism and/or ADD/ADHD disorders. Oftimes in preschool age children.. sleep deprivation due to many factors can cause symptoms that hint at other disorders. Good luck and thank-you for taking such an interest in the child's welfare.
