Koby the little blue kangaroo is a lot like many of our children who spend much of the day being worried. Koby worries about things like being late for school, or forgetting his lunch. He worries about losing a friend or losing a game. He even worries about not worrying. With his worries keeping his mind busy and his tummy in a tizzy, Koby comes to learn that worrying really doesn't change any of the things he worries about. With a little practice, he changes his worries into happy thoughts. Koby doesn't stop worrying forever, but he sure worries a lot less!
