The order, cleanliness, organization are some habits that children should learn, and must start with the things I used: toys.But we can not require a child to leave everything in place if we do not give you the facilities to do such as: organizing boxes, shelves, drawers, cupboards, etc.
You can store toys in a special room for games (in case of having the room) or within their own bedroom, determining a location or locations.
Toys should be near the playground, for example, ball, water games, they must be somewhere in the garden, the dolls in the bedroom or playroom.
Sort toys and store them according to their type, eg farm animals, pets, dinosaurs (animals), cars, trains, tracks (transport), memory, lotto, dominoes, ludo (games); blocks, puzzles, lego (Assembly Kit).
Preferably have the toys in a box, bag or clear plastic boxes that let you see inside, otherwise identify the boxes: If your child can read, a poster with the name (“Cars”), or if you have not read a poster with a picture of the content (drawing of a car).
Places of storage (drawers, cupboards, shelves, etc..) Must be at the height of your child, or enable a step stool to reach it.
It often happens that a child is ordered and to grow, it becomes cluttered, is a common but easily correctable, should only pay attention to make you remember to save all the children growing up want to do everything and feel that they lack time, so try to calm him and help put things away, with your help that will not lose much time as I thought and return to the habit of always.
One problem you may have is when a guest arrives home, and it does not have the same habits as his son, since this problem can become a good example for the little guest, for which they may need your help.Before you finish your game, make one last game: put everything in place, all must work together, then as your child has the habit, and can also participate brother and even you, the little guest will be motivated to do so, children learn by imitation.
