Sweet story
Format: Hardcover
Gave to a 9 year old grandson who has struggled with reading -- looked like a good choice. He seemed initially pleased.

Older picture books have better stories and hand drawn illustrations
Format: Paperback
Fun to read aloud, old-school, easy read by Diane DeGroat about classroom friendships, honesty, kindness, and fixing mistakes. K-2nd grade will enjoy.
So many of today’s children’s books lack depth, depend on dumb fart/poop jokes, are tied to tv shows/movies, or overfocus on moralizing and turning kids into little adults. Read for fun with your kids as often as you can! Check out children’s authors/illustrators from the 80’s and 90’s!

Entertaining and teaching book
Format: Paperback
I got this for Valentine’s Day for my 7 year-old grandson. I thought he’d enjoy the book as the title is funny, not “mushy.” He enjoyed reading the book to me, and I was pleasantly surprised to find a lesson on being kind.
