First of all, there is something wrong with the educational means and methods you adopt. Because "punishment" is not suitable for children as young as 4 years old. For children (including 4-year-old children) who have "wrong behavior" or negligence due to ignorance, persuasion and persuasion should be the main way to convince people by reasoning, and simple and rude attitudes and educational methods should be avoided.

Secondly, we should reasonably persuade. You should adopt ways and means acceptable to children and let them know why they are wrong and what the consequences will be. For example, teach children not to climb high places, pay attention to safety and fall easily. Is it more intuitive to let them watch the corresponding cartoons or to use an egg instead of "demonstration" to break the process? Is it more acceptable to children?

Finally, I suggest you read more books about educating children or consult some experienced parents, teachers and educators. May all children grow up healthily and happily!
