Doudehui couldn\’t understand. The balcony was so high, how could such a small baby climb up? The main cause of the incident is the most accountable. To prevent this danger from happening again, we must supervise ourselves as parents. It is our negligence and lack of dedication that caused such a terrible scene. So parents really need to wake up and don’t regret it until something really happens to them. What we have to do is just in case! I hope parents who have seen the video will forward it so that more families can see it and save more lives!
