Putting up decorations too early takes away some of the magic of Christmas, I feel. They are there so long they have less impact when Santa arrives – they become part of the backgorund.
I also think it is confusing for young children – they see decorations and trees and Santas so assume it is Christmas tomorrow – how hard it is to explain “no, Santa isn’t coming for another 2 or 3 months yet”. Frustrating for parents, too.
When do you put up a tree at home? Do you decorate the rest of the house as well?
