Using a qualitative descriptive investigation, Study 1 defines the changed behaviors and parenting styles that are recognized by teachers.

From these studies, it is clear that teachers feel that lifestyles of children are undesirable and are caught up in the life rhythm of parents. This creates a dilemma for teachers because this situation is a paradox based on the love of parents for the children. Although teachers must appeal to parents to improve the lifestyles of children, they must also create life rhythm in the school while considering this situation.
