I agree that children don't need to be lied to about things such as santa and fairies. It is such a double standard to say that it's wrong for children to lie, but it's ok for a parent to lie to a child. My 6 year old has always known that these characters are make believe, but still enjoys them. She write letters to santa every year and talks about him coming down the chimney etc, and she knows that it will be me playing the tooth fairy when she loses her first tooth. But this doesn't stop her enjoying the fun and fantasy of it all. Children usually understand that charaters in chidrens tv programmes are not real but it doesn't stop them enjoying them.
