As a teacher, you may have rich experience and skills in educating other people's children, but it may not be so easy to educate your own children directly. There may be several reasons for this:

1. Personality: Everyone has his own unique personality and style. If parents and children as teachers have different personalities, there may be educational conflicts.

2. Emotional factors: In some cases, parents who are teachers may bring home the pressure at work, thus affecting the education and parent-child relationship in the family.

3. Occupational limitations: As an educator, you can use different teaching methods and strategies when educating other people's children, but in family life, you may be limited by your occupation and it is difficult to use the same method.

4. Importance: In addition, parents' management and education procedures for their children may be too loose or too strict, instead of always strictly controlling the education process like professional teachers.

In a word, parents who are teachers may know how to educate their children better than other parents, but they are still parents and children are unique individuals. Successful education of children requires creating a healthy family environment, understanding and respecting children's unique needs, and adopting methods and strategies suitable for children's personality.
