Children in the spectrum find comfort in some repetitive behaviours that sometimes may look odd to others. This is called stimming and is short for self stimulating behaviour. It should mostly be ignored and given time to pass away unless it's likely to cause self harm. Once Madhav calmed down, he stopped clapping. And did the class continue to make a mess? Oh absolutely!
