This book is cute, but I'm critical of the model of consent portrayed. When the child is asked for hug by increasingly un-huggable characters, she gets less and less willing, but they keep hugging and it is not until she is entirely overwhelmed that she says "stop." I could see this book as a good conversation starter, with an adult asking ""Should porcupine have gone ahead and hugged her when she said 'oh boy' instead of yes or no?" and "Do you think the tiger should have agreed to the conditions for a hug without keeping them?" But without an alert reader, this book leans towards teaching ONLY that "no means no" rather than the "only yes means yes" model that we as a society should strive for.
