"Toys should be kept in the area where the family lives, not only in the child's room. Shelves are much more satisfying than toy boxes. Having order in the environment creates a feeling of security in the child, and trust in the environment. Baskets, trays, or small boxes neatly arranged on low shelves can be very helpful in creating this order."

"If you watch a child you will see which toys he plays with most and which ones just get dropped and forgotten. Try to keep only as many toys available to the child as can be kept neat, and uncrowded, in baskets on a shelf."

"Limiting the number of toys available at any one moment, and having a place for every toy, helps with the task of teaching the child to put toys away. But most important is the example set by the others in the environment. If the adult carefully and continually puts the pieces of puzzles or toys back in the basket in front of the child, she will eventually imitate and join in the activity. Sometimes the "putting away" into baskets is the most enjoyable part of play at this age." - Susan Mayclin Stephenson, Montessori Philosophy & Practice, Age 1-3 Years - Toys.
