Everybody needs a hobby, and tweens are no exception. Your babes may have been collecting rocks since they were toddlers. Now's the time to think about your tween's interests and abilities, and encourage something a little more challenging.
Some hobbies, like woodworking, fishing and photography, are individual pursuits. Others lend themselves to more social climates. Knitting groups, for example, encourage tweens to do something they enjoy while socializing and sharing skills. And ham radio hobbyists absolutely need another person on the receiving end.
If you're lucky, you and your child will share a hobby interest. Working side-by-side on a pleasurable project is great quality time. And you're likely to learn something from each other.
