1. The baby's cognitive ability is limited: the baby's visual, auditory and tactile cognitive abilities are not developed enough, and his cognitive ability to the surrounding environment and things is limited. Therefore, they are prone to accidents due to lack of judgment.

2. The baby's behavioral control ability is insufficient: the baby's motor coordination ability and sense of balance are not stable enough, and it is easy to lose balance and fall or encounter dangerous goods. In addition, they haven't fully mastered their self-control ability and can't obey the rules and instructions well.

3. The baby's growing environment is complex and changeable: As the baby grows up, they will come into contact with more and more new things and new environments, such as roads, elevators and electrical appliances. If safety education is not carried out in time, the baby may face greater danger.

4. Cultivate good safety habits: Safety education from an early age can help your baby develop good safety habits, such as not touching strangers at will, not eating indiscriminately, and not running around. These habits help to protect the baby's life safety and health.

To sum up, the baby's safety education needs to start from an early age to help them establish correct safety awareness and behavior habits to prevent accidents.
