Effort allocation: Teachers need to deal with a lot of student work, supervise classes, prepare instructional materials, and so on every day, which is a very heavy job. If the teacher also has to take care of their own children, they may not have enough energy. The profession of a teacher requires them to have a high level of concentration and organization, which are also traits that they expect to see in their students in their teaching.
Role Conflict: As a teacher, the role is that of an educator and the role is to help students grow and develop. If you play the role of a parent at the same time, it can be difficult to remain objective and professional. Especially when a teacher's personal emotions and values may conflict with their role in the classroom, it can be stressful.
Professional autonomy: Teachers often want to work freely within their own area of expertise, without external interference. If they need to take care of household chores or take care of children, they may be interrupted, affecting their professional autonomy and productivity.
This does not mean that all teachers are reluctant to teach their children, and some teachers may find that caring for their children is a special experience that helps them better understand the needs of parents and children so that they can better fulfill their responsibilities in the process of educating their children. Additionally, some teachers may find that taking care of their own children helps them understand their students better, providing a more personalized education.
