Fun Lessons
Format: Paperback
You can never go wrong with reading a Richard Scarry book. This book teaches manners to young children very well. My young granddaughter has started speaking in complete sentences, and she is using please and thank you. This book is a good introduction for using these words.

Fun way to learn good behavior!
Format: Paperback
Good value for the price, you get 7 short stories with this book & the illustrations are very well done. If your child's attention span can't handle the entire book you can still manage a few. Lots of funny action pictures to hold their interest, my 4 1/2 yr old son flips through the book on his own just to look at the pictures and they are descriptive enough to follow the story without reading the words. It's a favorite book to listen to because he is of age to get in trouble and to be held accountable, so he likes to see that he is not the only one. His favorite story is Pig Will and Pig Won't. Hint: Say "I won't" with an angry piggy snort! This cracks kids up, they will anticipate the words and snort along with you "I won't"! Sometimes works to change a defiant or lazy mood when I ask him to do something, I will ask "is my D. a pig will or pig won't today?".. helps to snort a little! Can't overuse it though..

too advanced for 18month old, but great book!
Format: Paperback
I love Richard Scarry! I bought this book for my 18 month old, who we are trying to teach to say please and thank you. Unfortunately this book is just way too advanced for her. It's full on stories rather than short pieces. I know, the suggested age was older but that is true for a lot of books that really can be enjoyed by younger tots. This one will be put away for at least another 6 months, and then kept on the shelf of "appropriate" but not in her board book box. However, I really like that she can now say "Lowly" :) Richard Scarry is one of my favorite authors/illustrators from childhood and I'm glad to have this book. It just is beyond the reach of my LO at this age.
