Life's Lessons
Format: Hardcover
This is such a delightful story that every child can relate to in the little mishaps of life.
It brought a smile to my face as I pictured "Grandpa" offering comfort and encouragement.
It is a lesson for all ages and bigger problems in life as well...."Don't Worry, Stay Happy."
Thank you, Nicole, for sharing your story.

Definitely recommend this!
Format: Kindle
This is a wonderfully written and beautifully illustrated story about a boy teaching others to be kind. There are many examples of being kind with even more suggestions at the end of the book. We ALL need to be kind to others because the world is a better place to be if we respect others and are nice to them. Being mean or selfish diminishes us and makes the world more inhospitable.
