    Good read
    Very good basic subjective author. Some modern therapist offer a different perspective on rewards and child behavior, but to be expected in academia. As with any behavioral psychology observable or behavioral science documents - measure the subjective amount against the scientific controlling evidence being offerred. If no evidence - it is just subjective opinion.

    Not JUST a Parenting Book
    Format: Hardcover
    Good Inside and Dr. Becky are everything the world needs now. A strong, sturdy perspective that truly, wholeheartedly believes in the good inside us all. That is truly not cheap talk. It. is. the. real. deal. This book is a parenting book that covers big picture philosophical understandings of parenthood AND the more practical, day-to-day implementation of said philosophies. Dr. Becky is incredible about explaining the underlying reasons for why kids do what they do and why WE respond as we do and then she talks us through exactly how to apply the "most generous interpretation" so that we can do better for the next generation AND for ourselves. Good Inside is also a REparenting book and a leadership book. She will teach you how to show up for the realness of your own life for yourself and for the kids that you love most dearly. Truly, there is not a better way to spend your money. Maybe go ahead and stock up on highlighters and your favorite pens too because, if you're like me, you will be highlighting and underlining left and right. It's truly that game-changing. Get ready to finally understand your job description as a parent and your kids' job descriptions as wonderful, little growing humans in the world. And if you yourself need healing from your own childhood, this will open the door for that too. I know that you, dear Amazon review reader, do not know me but I am not really prone to hyperbole. I do not feel it is an exaggeration to say that Dr. Becky and Good Inside is game-changing. This purchase is truly an investment in yourself and the kind of parent and person you want to be and an investment in your kids and their future.

    Good advice overall
    Format: Paperback
    This is an interesting read to help with your child’s self esteem and behavior. The first several chapters on the psychology behind behavior were more helpful and interesting than the second half of the book that addresses specific behaviors. Also, if you follow Dr Becky on social media, most of her advice is already in her content. However, I’m glad I read this book, even it wasn’t life changing.

    So incredibly helpful with sensitive kiddo
    Format: Hardcover
    This book has been so, so wonderfully helpful, my husband jokes it’s now my bible. Kiddo went from like 10-20 meltdowns a day to only a couple, and those are resolved in like a tenth of the time. I feel so much less frustrated and more connected, and able to handle it when he does dysregulate in a way that makes me proud. It’s also honestly been healing for me as a child of loving parents who nonetheless didn’t learn all this stuff and did a lot of invalidating and shaming. It’s great theory and very easily digestible and applicable practice combined. I wish I’d found it 3 years sooner and I can’t recommend it enough.
