I have a main OCD and that is my daughters room.
My toddlers have a lovely little girls room, with matching chair, cribs, dresses all over their closet and lovely sayings on the wall.
Every night their room must be clean, every two weeks I go through and deep clean it. They get clean sheets every week and laundry is done twice a week.
I can't sleep at night without this room being clean... I love their room, it's so peaceful for me.
