I usually put my decorations up in the last week of December.
This year I'm so busy with work, we have had a bereavement in the family and my little is asking for them to go up now as the shops are full of Xmas stuff and all the street lights are on.
I absolutely love having the decorations up and don't mind one bit and would be nice to cheer him up but I think my neighbours would think I was crazy putting them up so early !
