I Can't Sleep by Stephanie Blake
Simon the Rabbit, from the kids (and adults!) favourite 'Poo Bum' is back, only this time he's a little bit more grown up, with his little brother Caspar to look after. When Caspar leaves is blanket outside after they have finished playing, his big brother steps up to go out into the dark night to retrieve it. A lovely story about siblings, and a great one for reading aloud due to the repetition and the chance to put on voices for Caspar and Simon and use lots of exaggerated expression.
