Your children appreciate when you hold them accountable for their success. They get a sense of accomplishment when you let them complete their own homework.
Do you recognize when your child is struggling? If so what do you do when they are having a hard time? If you don't feel confident helping them make sure you get them some help. How do you that? Communicate with your child's teacher. If she has limited time seek the help of a tutor.
