Must have pre-schooler book on kindness/empathy
Format: Hardcover, Format: Hardcover
This is great because it gives lots of tangible acts of kindness that a toddler/preschooler can understand. It has a feel of preventing bullying by encouraging kindness towards your peers at a young age. It touches upon gratitude and empathy. There is a wonderful range of diversity in skin tones and also includes a child with waking aid & one with a hearing aid. Illustrations are bright and basic. Arms & hands of characters are sort of stiff, so while a previous review implies there is something wrong you would really have to be looking closely and making assumptions to find hands between the waist and knees doing anything wrong.

Inclusion- without making that the focal point!
Format: Hardcover
This book shows representation for physical disabilities and different skin tones without that being the headliner of the book. It also emphasizes being kind to anyone/ everyone - and not because they are different. Showing children with hearing aids drawing pictures to cheer someone up (with no mention of the disability) or showing a child with assisted walking needs planting seeds at a community garden- These children are not the victims of this book who need kindness, but are thoughtfully included to be spreading kindness to others.

This book is worth your time!
Format: Hardcover
Purchased this book because I’m in a Kindergarten classroom and teaching Kindness is so important to me. This book is beautifully illustrated with great art work that invokes questions. So much is going on in each page and children pay attention to it all! This book is worth getting and you will not regret it! I’m so glad I purchased it. I was gonna donate it to the class but I decided to keep it for when my niece and nephew come over to my house to sleepover. Great book!

A hit with 17 Mo Grandson
Format: Hardcover
Bot for 17 mo old grandson. The words were too much for him to understand but he loved the bright color pictures. We had to read it 3 times the first day. It is very sturdy so he can turn the pages easily. The sentiments used are very good and the characters very diverse.
