All day long mother does her chores without the help of her regular assistant, Susan. Instead, a tiger appears, ready to help with the dishes, an elephant picks up the clothespins, a monkey accompanies her to market and mother has lunch with a pig and dinner with a rabbit. Wondering if Susan will ever return, mother tiptoes into her room and sings a favorite song. ""Then very softly, someone came in. 'I'm back', said Susan. And she was."" Youngsters familiar with changing species a dozen times during the day will delight in this story and adore a mother who can play her own role to the hilt. Peter Edwards' colorful illustrations provides the visual humor in this funny little secret Miss Udry shares with her audience.
