It's Not as Hard as You Think
Think of it this way: If the house is clean - I mean really clean - it will eliminate more stress than it causes you to get it done in the first place!
And.... once it is done, instead of spending hours each week keeping it up, it will take a few minutes each day. This leaves a lot of time for enjoying the season, and removes one more item from the 'to-do' list for your perfect holiday!!
To keep things manageable, make a separate Christmas cleaning list for each room of the house. Keep the chores on this list simple. Next to each item, insert the name of a family member who will be responsible for that chore.
Because Christmas cleaning work has to fit into the existing schedule, plug only one room per day into your Christmas calendar. If you find that your family is more cooperative than most, it might be possible to do more than one room per day. However, on the calendar, keep your Christmas cleaning chores to only one room a day - even if it only looks like less work that way.
Make sure that each family member understands that these chores are to be accomplished on the day in question, and hold them accountable for doing so!!
