The Bridal Wreath by Sigrid Undset — Read

The spring after Kristin's long journey, Ragnfrid bore her husband another daughter. Both father and mother had wished indeed that it might be a son, but they soon took comfort, and were filled with the tenderest love for little Ulvhild. She was a most fair child, healthy, good, happy and quiet. Ragnfrid doted so on this new baby that she went on suckling it during the second year of its life; wherefore, on Sira Eirik's counsel, she left off somewhat her strict fasts and religious exercises while she had the child at the breast. On this account and by reason of her joy in Ulvhild, her bloom came back to her, and Lavrans thought he had never seen his wife so happy or so fair and kindly in all the years he had been wed.

Kristin, too, felt that great happiness had come to them with this tender little sister. That her mother's heavy mood made a stillness about her home, had never come into her thought; she had deemed it was but as it should be that her mother should correct and chide her, while her father played and jested with her. But Ragnfrid was much gentler with her now and gave her more freedom; petted her more too; and so Kristin little heeded that her mother had much less time to tend her. She loved Ulvhild as much as the others, and was joyful when they let her carry or rock her sister, and in time there was still more sport with the little one when she began to creep and walk and talk and Kristin could play with her.
