Before you begin this exercise, make sure you have provided enough space where all the stuff can go. If the cupboards or drawers are full and overflowing, you can't expect them to put their stuff in them. You will have to reorganize the storage space or even install some additional shelves, boxes under the bed, or chests of drawers to accommodate all the things that are precious to your child.

Ideally you want enough storage space so that there is still some spare capacity even after everything has been tidied up. Otherwise, if everything is crammed in, it can be very hard to find anything when you want it - which makes the solution of scattering everything across the floor rather attractive.

Next thing to do is to make a routine and set up reasonable expectations. Many children are by nature very meticulous and organized; some are not. Also, their concept of tidiness may be very different from yours. If you think you can see their room spic and span all through the day, you are mistaken. It is an unreasonable expectation; it will only lead to frustration. It would be better if you take your child's views and then establish a reasonable standard of tidiness, and how often that should be achieved.

Remember, your goal should be to teach your children how to responsibly look after their belongings; it should not be to showcase a spic and span room to show off to others. If you are taking up this exercise only because the untidiness gets on your nerves, then stop and think again. This will not help you or your child. Set your emotions aside and focus on teaching a good habit to your child. Therefore, you will have to be patient and live with an untidy room at times.

Reasonable expectations could be putting things away before bed and a thorough tidy-up once a week. Then it is time to make a contract.

What this says, in very simple terms, is what are the consequences for success and failure? For example, if the agreement is that they will do a big clean up before lunchtime on Saturday, what happens if they do, or don't, achieve that?

Again, the focus should be on rewards not punishments. Give them earned privileges based on achieving the goal. You may want to combine them with a chart system connected to other chores.

In rare cases you can use some punishments for failure, but only as a last resort. And, the punishment should commensurate with the crime. You may want to try out the "black bag" technique, which is to put all scattered things in a big black bag which will be thrown into the attic, basement or garage for a week. If they tidy up the room by next Saturday, they can have it back. If not, then the next week's black bag collection is also thrown into the basement. This continues until they do some tidying up!

The secret of success of this exercise is in remaining calm and firm. Avoid shouting or other punishments. Just go at the appointed time and collect the offending articles.

You will need to do it only a couple of times because if you mean business, most children will hate the sight of the black bag and tidy up the room before they have to set eyes on it again.

There may be times when you want their room to be tidied because you are expecting guests. This is your need and you need to borrow your child's room for a night or two. So, don't include this in the contract. For this, you must give extra incentives for tidying up the room.
