When baby brother is sleeping, it's time to be ever so quiet. There's no singing or jumping or laughing at all. Even the toys need to be quiet! The pirates stop firing their cannons, the knights stop fighting, even the tiger stops growling. But when baby wakes up . . . it's time to jump and laugh and sing again! And the knights begin to fight, the pirates fire up the cannons, and the tiger growls so loudly! Until it's time to be quiet once again. In this beautifully and expressively illustrated picture book, we celebrate the love between siblings as a big brother uses his imagination to calm his urge to cause a ruckus so that his little brother can sleep.
