A tween is a child between the ages of 8 and 12. This age group is called "tweens" because they are in between children and teenagers. During this period, children experience significant changes as they approach puberty. They become more independent, start to care more about what other people think about them, and may become oversensitive and insecure. They also begin to develop their cognitive skills to think and reason, and they start making plans for short-term and long-term goals. As parents, it is important to provide structure, guidance, and detailed discussions on various topics to help them navigate through these changes.
