When Daniel was 4 years old, his nursery teachers noticed that he behaved differently from his peers. He struggled to use language to communicate his needs, often pulling a teacher's hand towards an object instead of speaking. During group play, Daniel ignored the other children and preferred to sit by himself, showing no interest in sharing or interacting with them. He spent hours lining up plastic building blocks in a strict sequence of colours, becoming highly distressed if any block was moved out of order.
