Replacing toys
Most often, this trick is suitable for babies, that is, children under 3-4 years old, whose memory is not so extensive as to remember all their toys. Mom just needs to remove part of the toys for a while, which the child missed, and after some time to get them. Surprisingly, each time children perceive toys as new and can engage in them for a long time, completely forgetting that you can buy new ones in the store.
