Time for Bed, Spot by Eric Hill
It's time for bed but Spot isn't sleepy. He wants to play with his toys. Sam and Sally try to help him get to sleep by reading him a story and giving him a bath. But Spot STILL isn't sleepy. He wants to play dressing-up. Eventually, he tires himself out and falls asleep on his pile of fancy-dress clothes. Sally then puts Spot to bed.
