Many negative messages, such as grimaces, body stiffness, sighs, raised eyebrows, etc., could communicate a negative message. This could add to the tension of the homework relationship. This is extremely important with younger children who cannot distinguish between loss of parental approval and loss of love. Avoid finishing assignments for your child. While the motivation may be to help finish a difficult assignment, the end result may be very destructive.
Children tend to feel inadequate when a parent finishes homework.
If your child cannot complete an assignment, and have honestly tried, write the teacher a note explaining the circumstances.
