"WHEN I look back," Mary Fields said, "I marvel that we ever could have grown up without a Nanny to take care of us."

There was no doubt that Nanny had changed the whole life of the Fields's house since she had come. From the time the children opened their eyes in the morning to their last sleepy nod at night, Nanny was in there with them, watching them, hovering about them, seeing that all their wants were taken care of.

Mr. Fields knew, when he went to the office, that his kids were safe, perfectly safe. And Mary was relieved of a countless procession of chores and worries. She did not have to wake the children up, dress them, see that they were washed, ate their meals, or anything else. She did not even have to take them to school. And after school, if they did not come right home, she did not have to pace back and forth in anxiety, worried that something had happened to them.

Not that Nanny spoiled them, of course. When they demanded something absurd or harmful (a whole storeful of candy, or a policeman's motorcycle) Nanny's will was like iron. Like a good shepherd she knew when to refuse the flock its wishes.

Both children loved her. Once, when Nanny had to be sent to the repair shop, they cried and cried without stopping. Neither their mother nor their father could console them. But at last Nanny was back again, and everything was all right. And just in time! Mrs. Fields was exhausted.

"Lord," she said, throwing herself down. "What would we do without her?"

Mr. Fields looked up. "Without who?"

"Without Nanny."

"Heaven only knows," Mr. Fields said. After Nanny had aroused the children from sleep—by emitting a soft, musical whirr a few feet from their heads—she made certain that they were dressed and down at the breakfast table promptly, with faces clean and dispositions unclouded. If they were cross Nanny allowed them the pleasure of riding downstairs on her back.
