Santa 'teaches kids to be good'

He knows if she's been bad or good
He sees them when they're sleeping. He knows when they're awake - and believing in him helps children to be good, according to a psychiatrist.
Santa Claus - and his ability to "know if you've been bad or good" - helps children learn the difference between right and wrong, said Dr Lynda Breen.

Writing in this month's Psychiatric Bulletin, she said the Santa myth gives parents an "ace up their sleeve".

She said it was parents who are upset when children stop believing in Santa.
