So if not, it could be a sign that autism is present. Lack of facial expressions and gestures is also a sign. An autistic baby may not smile or show any type of joy.
When the infant gets a little older and able to explore on their own there could be some other signs of autism in the infant. If the baby does not look for you or show any affection towards you it could very well be a sign. Autistic child lack affection and tend to fend for themselves.
