Yes, Bella - the presents are supposed to be opened on Christmas Eve - after 4 pm the shops shut and everyone is supposed to be in their best clothes, the house cleaned, the tree decorated, and everyone in a good mood with a cup of coffee and cakes on the table. I doubt anyone has ever managed that unless they had a house full of helpful elves.
On 6 December the children also get a load of presents for Nikolaus - they are supposed to put out a boot or a shoe over night and it is filled with small things like nuts and tangerines, but this has got out of hand and some will get a table full of goodies - toys and games, books, clothes and sweets or even money.
Years ago, we had real candles, as did my parents-in-law, in addition to the advent wreath, which by the end of advent was pretty dry and with four candles almost burnt down, was a great danger and often a cause of house fires.
Anyway, sorry, this is nothing to do with the topic of the thread. It does, however, show that there are big differences in the traditions, and where they meet and contradict, small children can get confused, and from the age of about 4, aren't really convinced by anything.
It doesn't make them any the less imaginative or child-like, though. They accept it as just another story.
