Cute picturization
Format: Board book
Like the picturization really really cute sandpiper babies! You might have to come up with your names for the piper babies as the names given peep and piper don't stand out when narrating the story to kids. But it's a cute book to have.

We got this set for our baby shower and my 4 month old son LOVES them! He coos at every page. The pictures are amazing and I like how each page rhymes and has interesting facts about all the different animals.

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.
