2. Self-examination: Help children develop a good habit of self-examination, such as encouraging children to check oral hygiene in front of a mirror to ensure dental health; You can also ask them to check whether their toiletries are clean.

3. Provide appropriate tools: provide appropriate tools and facilities, such as towels and washing machines, to facilitate children's personal hygiene and make it easier for them to develop good hygiene habits.

4. Give positive incentives: praise your child's efforts and progress, such as brushing your teeth, washing your hands and taking a bath in time. After the child does something right, give appropriate rewards to motivate the child to maintain his hygiene.
