Watch your baby to see if he interacts with his surroundings. An indifference to surroundings, even if they change, is one of the autism symptoms that often appears in infants.
Take note if your baby is happier when playing by herself. if your baby does not respond to other people, autism could be the cause. Autistic babies do not enjoy the interaction with others that most babies enjoy.
Notice if your baby is not interested in toys or other objects of interest. An autistic baby may not track colorful items with his eyes or turn his head toward the voice of mom or dad.
Watch your young child's language development. Delayed language development is another autism symptom to take note of when deciding whether or not to talk to your child's doctor or teacher. Lack of expression or intonation can also indicate autism is present.
Look for repeated actions in young children. A child that constantly flaps her arms, for instance, may be exhibiting autism symptoms. Uneven motor skills can also indicate a problem.
Pay attention to your child's eye contact. A young child who avoids eye contact could be autistic.
Talk to your child's doctor and teachers if you notice problems that could indicate autism. Remember that some children exhibit autism symptoms without actually having the condition, but you should have your child evaluated to be sure. Early intervention is the key to success with autistic children.
