Irresponsiveness. Don’t wonder if the child suffering from autism does not react to your actions or questions – they ignore you unintentionally. Newborn babies may be unresponsive to the environment and people around them due to the early form of autism. No sound is able to distract their attention. Usually, babies tend to explore the world by communicating and playing with other people when they first learn how to walk, but kids with autism like being alone.
