Children "do grow at night"

Scientists have admitted that the notion that children grow taller while they sleep is probably true. As the BBC http://www.bbc.co.uk reports, researchers at the University of Wisconsin http://www.wisc.edu put sensors in the leg bones of baby lambs and confirmed that most growth spurts occurred when the animals were at rest or sleeping. According to the scientists, the same is true in humans, and this could help explain why some children suffer from growing pains at night.
