The child is not without courage, but does not understand the danger and consequences of this behavior. Be sure to do a good job in safety education, educate him every day and tell him that it is dangerous. If you can't do it, at least let him know that you can't do those things, otherwise you won't regret it more. You might as well hit him twice. Be sure to let the baby realize that his behavior is dangerous and not allowed, and be sure to take some safety measures.
