If you haven't already, take some time to declutter your children's rooms before Christmas. Throw away anything that is broken. Toys that are outgrown or not used can be passed down to a sibling or stored for future use. Or give them to a friend or charity. Don't stop until there is no clutter and the room is peaceful. When Christmas comes, there will be adequate space for your child's new toys!
Make sure your child has a system - a place for books, a place for larger toys (I recommend shelves), bins or boxes for toys with many parts, a place for collections or special items, and a place for papers, a trash can, and a laundry basket.
Set aside time each day for your child to maintain the system - time to make the bed, put away toys, throw away trash, put clothes in the laundry basket, etc.
