A "tween" refers to a child typically aged between 9 and 12 years old. This stage comes after childhood and before adolescence, marking a period of significant physical, emotional, and social development. Tweens often experience changes in their interests, friendships, and self-identity as they begin to seek independence. During the tween years, children may become more influenced by peer pressure and start to explore hobbies and activities that reflect their growing individuality. They may also engage with social media and technology, which can impact their social interactions and self-esteem.
