I have found that good behavior does not always come back on. There are a lot of factors to be considered like the type of toy, how many times they played with it and for what duration before returning it. For example if you take away a child’s favorite toy and replace it with another one, chances are he will play more often with the new toy because this is now his favorite thing in life! The only way we can get them to behave properly again is by giving them their original toy back.
