Length of sleep key in regulating kids' behaviours: study

From the CBC News
How long children sleep every night can affect their behavioural patterns and lead to changes in eating habits, a new study suggests.

The study, which was conducted by researchers at the University of Auckland, found that the less time a child slept, the more likely they were to have behavioural problems.

Children who slept for less than nine hours were also more likely to become overweight or obese, according to the study.
