Billy Andersen and his Troubles by L.T. Meade

All that day Billy anxiously watched the baby; he tore off her wet clothes, and wrapped the blanket and the sheet tightly round her, and then he coaxed a neighbor to expend one of his pennies on milk, which he warmed and gave with some broken bread to the little hungry creature. He forgot all about himself in his anxiety for Sarah Ann, and as the day passed on, and she did not sneeze any more, but sat quite warm and bright and chirrupy in his arms, he became more and more light-hearted, and more and more thankful. In his thankfulness he would have offered a little prayer to God, had he known how, for his mother was just sufficiently not a heathen to say to him, now and then, "Don't go out without saying your prayers, Billy, be sure you say your prayers," and once or twice she had even tried to teach him a clause out of Our Father. He only remembered the first two words now, and, looking at the baby, he repeated them solemnly several times. At last it was time to go to bed, and as Sarah Ann was quite nice and sleepy, Billy hoped they would have a comfortable night. So they might have had, as far as the baby was concerned, for she nestled off so peacefully, and laid her soft head on Billy's breast.

But what ailed the poor little boy himself? His head ached, his pulse throbbed as he lay with the scanty blankets covering him; he shivered so violently that he almost feared he should wake Sarah Ann. Yes, he, not the baby, had taken cold. He, not the baby, was going to have brownchitis or that hinflammation which he dreaded.
