Get involved in your child's activities. Go to the ballet recitals, baseball games, school concerts, etc. Your presence shows your child that you care. An idea that works really well with younger children is to create some type of family project where each child has a specific task. The choice depends on the interests of your family.
Children like to feel needed.
Assigning them a task such as making their bed or dusting the furniture makes them feel important. Whenever possible, read to your child. Encourage your child to ask questions and comments on the story. Exhibit confidence yourself. They can read adults like a book.
