Explore the environment
When children are familiar with the environment, they usually explore by "seeing", "touching" and "moving". So what he doesn't want to touch is put where he can't get it, 1-2 years later, which is good for adults and children.
Don't rob
Although children can understand their parents' words, they can't understand them as truth. In other words, he can't apply what he has learned to ordinary things, and this ability can only be possessed in primary and secondary schools. Therefore, the education that is not robbed should be specific to each item, not general.
