For example, as mentioned in the book, it is agreed with the child in advance that if the toys are not packed, a condom will be put on the TV. When they see condoms on TV, they are reminding children that toys are not packaged. Because this is discussed with the children in advance, the children will be happy to implement the agreements they have participated in and agreed to, and avoid chattering when they see toys all over the floor. Failure to solve problems also helps children develop the habit of "relying on others and being irresponsible".
This also reminds me that if you want to form a good habit, you can also set a trigger point. For example, to form the habit of reading, you can first think about under what circumstances you can read. For example, when taking a subway plane, or when going to the toilet, before going to bed, and so on. When you decide to read a book before going to bed, you might as well put the book on the bed and remind yourself to read a book before going to bed as soon as you see it, thus forming a good habit of reading before going to bed. This is similar to a silent signal. I look forward to helping myself and everyone move towards a better self through these simple and wordless messages.
