A World of Girls by L.T. Meade

In the morning Nan was better, and although for days she was in a very precarious state, and had to be kept as quiet as possible, yet Miss Danesbury's great dread that fever would set in had passed away. The doctor said, however, that Nan had barely escaped real injury to her brain, and that it would be many a day before she would romp again, and play freely and noisily with the other children. Nan had chosen her own nurse, and, with the imperiousness of all babies -- to say nothing of sick babies -- she had her way. From morning till night Annie remained with her, and when the doctor saw how Annie alone could soothe and satisfy the child he would not allow it to be otherwise. At first Nan would lie with her hand in Annie's, and her little cry of "sing, Annie," going on from time to time; but as she grew better Annie would sit with her by the open window, with her head pillowed on her breast, and her arm round the little slender form, and Nan would smile and look adoringly at Annie, who would often return her gaze with intense sadness, and an indescribable something in her face which caused the little one to stroke her cheek tenderly, and say in her sweet baby voice:

"Poor Annie; poor tibby Annie!"
