Inspired by another post, I'm wondering whether there are books that are foolproof for getting your toddler to drift off. I received this book as a gift and it's so boring I nearly fall asleep whilst reading it myself, but my three year old finds it so calming and it does the job in terms of getting her to settle down and slumber.
