I think this is how Santa Claus should be conveyed to children: "Kids, we have a fat fellow in a red suit on our tree to remind us of Saint Klaus/Nicholas who lived in Lapland and gave presents to poor children in his region."

Saint Nicholas/Santa Claus/Sinter Klaus is a wonderful symbol of the true spirit of Christmas, and I think he was a good Christian who tried to follow God's example by giving gifts to people who could not repay him.

I wouldn't want my children to write letters to him, though. He's dead, after all.

I think teaching kids that he comes with presents for them, or that there is a tooth fairy or an Easter bunny teaches them that what you say about what they can't see isn't truthful.

I think that hurts their perception of God.

So, children should be told truthful things by their parents. And children should trust their parents. It's important that they know they can depend on their parents, on the police, on the fire department, and most importantly, on God.
