Perfect aged book
Format: Paperback
I truly liked this book for our son when he was 3 years old. It was done very simple and to the point. It allowed you as a parent to add on if you wanted and to talk about the pages. This was a very helpful book in our house.

Engaging & Effective for toddlers w/Autism!
Format: Paperback, Format: Paperback
My almost 3 year old was recently diagnosed with Autism. He struggles with transitions and also has a speech delay, which often contributes to big meltdowns when he doesn’t get his way. He’s been a “hitter” since about 18M… and it’s so hard! I know he has big emotions and can’t regulate them easily. This book is FANTASTIC! It’s easy to read and has cute and relatable illustrations.
It can be a little repetitive, but that’s what helps get the point across. Let’s face it, my son is also very repetitive, so it seems to resonate with him. It talks about different feelings and emotions, how it’s ok to feel that way, and how to handle them without hitting. For example, you can use your words to ask a grownup for help; you can draw an angry picture; you can squeeze your hands into a ball and release them, etc. There’s different options for different scenarios, and each one is described in a way that toddlers can figure out how to do it themselves. His favorite is to squeeze his hands into a fist, or give his body a big “squeeze hug.” I’ve already caught him doing that a few times instead of slapping me!
It’ll take practice (like the book mentions) but I think he’ll be able to self-regulate better with some of these ideas!! I also have some new phrases to use and picked up some sign language. I love the tips for caregivers in the back!
If you have a hitter (especially one on the spectrum), you need this! I actually like it better than our other book, Hands Are Not for Hitting. Similar story line, but this one is more detailed and better suited for older toddlers. I highly recommend it!!
Hope this helps ☺️

Wonderful Book for Toddlers and Up!
Format: Paperback, Format: Paperback
Great book for toddlers or older! I bought this for my 2.5 y.o. and she would request me to read it every night. She would demonstrate some of the techniques described in the book at her own voilition, which was awesome because it showed that a couple methods were 'sticking.' The next step was trying to help her to perform the technique when needed....like when wanting to hit her brother, which is a bit more challenging!
The illustrations are beautiful, large, and colorful. There's one sentence that I think is confusing for little ones to comprehend, such as the breathing method you'd use when blowing bubbles or a pinwheel. I wish there was an "as if" in there so it's taken less literally. However, the flow of the book is nice. It goes through situations which might occur, how you might feel, and then the techniques. Love the page that summarizes all the techniques and the 6 strategies in the back for parents. The pages are a slightly thicker than most paperbacks for kids - more durable for sure, which I appreciate. It's written by a child psychologist, so you know it's going to be a book of quality!

Well done
Format: Hardcover
Beautiful book. Big, beautiful illustrations. The reading is easy though some of the concepts may be a little difficult for younger ones to grasp. Though this just leaves a great opportunity for further discussion on all the different reasons for crying. Great teaching tool. The illustrations do a wonderful job depicting these deeper concepts. Readers may find themselves lingering a little bit on each page, after the reading is done, absorbing the meaning of the words and pictures. Very well done.
