Liam is two-years old. His mother is concerned about his behavior. Liam is very different from how his sister Briana was when she was his age. He does not make eye contact. When she smiles at him, he doesn't smile back. He doesn't seem to like her hugging or kissing him. It seems Liam has autism spectrum disorder.

Explanation:

Autism spectrum disorder (ASD), commonly known just as autism, is a developmental disorder which consists of difficulties regarding communication, social interaction, and behavior. In general, symptoms appear during childhood. In this case, Liam is two years old. At that age, kids begin to develop some social skills. Kids with autism tend to have difficulties making eye contact, smiling, coping with noises. They also tend to have repetitive behaviors and also lack the ability to be empathic in some situations. ASD has different levels, that's why some kids can have a quite normal upbringing and some others need more help and assistance.
