Accidental injury has become the biggest killer of babies. Doctor's Forum: According to the survey of accidental injuries of 43,000 preschool children and primary and secondary school students in1kloc-0/cities across the country, 20%~40% of children in China need medical treatment every year because of accidental injuries. Accidental injury of children has been regarded as one of the most serious social, economic and medical problems. So what makes the baby so vulnerable to accidental injuries? First of all, with the development of social economy, the change of people's lifestyle, the popularization of household appliances, the high-rise of urban buildings and the large increase of vehicles, especially cars, have become new factors threatening children's life safety. Wang Xinliang, Pediatric Department, Second Hospital of Hebei Medical University Secondly, parents' lack of safety awareness and knowledge led to many tragedies that should not have happened. For example, a parent in Beijing put a Japanese bean in his mouth to make his 5-year-old child happy. Results Japanese beans mistakenly entered the trachea, and finally the baby suffocated and died. ? Furthermore, children are fresh and curious about everything in the process of growth and development, and have a strong desire to explore, but their own functional level is low, and they lack sufficient experience and safety awareness and ability, so they often become victims when faced with danger or potential danger. Therefore, parents must always be vigilant to ensure that their children have a safe living environment. First of all, we should establish the awareness of safety first and strengthen the knowledge learning of safety; Secondly, combine the baby's life with safety education to improve the baby's awareness and ability of self-protection. That is, while paying attention to children and protecting them, we should also teach them the necessary safety knowledge and improve their self-protection ability. Third, and most fundamentally, we must strengthen the baby's physique and cultivate and train the baby to develop good living habits. Strong physique can resist injuries, and good living habits will reduce the occurrence of injury accidents.
