Have You Filled a Bucket Today? A Guide to Daily Happiness for Kids

Have You Filled a Bucket Today? A Guide to Daily Happiness for Kids - Carol McCloud This is a wonderfully written and illustrated book for children between the ages of 4-9.

The idea of this book is to teach and guide children in learning how they can "fill the imaginary bucket that everyone in the world possesses, and the buckets of others" by treating people with kindness and respect.
They are also taught that you can empty their bucket and the bucket of others by being unkind and disrespectful.
