Just got this book called "Shhh!!" out of the library for my 3 year old and read it.
I read it in a whisper, as the book is about not waking up a giant. There are flaps for interaction that we had to open throughout the book to ensure that we did not wake any of the giants pets up that were sleeping or disturb the giants wife cooking when we turned each page. If the giant knew we were there he would eat us for his tea, so we had to be very quite.
It is a real good calm down story just before bedtime and it gave my lo a bit of a thrill at the end, but I won't spoil the fun by telling you what happens.
If you can get the book out of your local library do it's a great read.
