At three years old, he published a book about not wasting food — and set a world record

Advay Jain of South Brunswick, New Jersey, was 3 years and 345 days old when his picture book about a young dinosaur learning to value food was released — making him, Guinness World Records confirms, the youngest male ever to publish a book. The idea grew out of his own move to a new preschool, where meals came from school rather than home. Now four, he has sold more than 1,300 copies, after a childhood spent drawing his stories on the walls at home while his parents chose to nurture the habit rather than scold it.
