This book is really, really cute. The marketplace is always flooded with ‘goodnight book’ options, and I’ve found it’s hard to distinguish some from others. Good Night, Me is a sweet and simple goodnight book by Andrew Daddo, illus by Emma Quay.
My favourite aspect of this book is that it follows the goodnight routine of an orang-utan who is genderless. This means it does not privilege or work towards gendering some aspect of your child’s bedtime.
The pages go through parts of the body, and what is their function, whilst wishing them each a good night, eg. “Neck, could you please just place my head on that pillow? That’s it.”
It is very saccharine, and if that isn’t your thing, then this book is not the one for you. But, for the rest of us ‘good night’ wishers, check it out. http://www.andrewdaddo.com/?page_id=17
