About the death of children in infancy, which requires certain ritual actions to prevent it.

Compare Russian dialectal "not to stand" with the same meaning: <…> а у Матрёны с Ефимом дети не стояли: до трех месяцев не доживая и не болея ничем, умирал каждый (А.Соженицын. Матренин двор) and Matryona and Efim's children did not stand: each one died before reaching three months of age and without being ill with anything (A. Sozhenitsyn. Matryona's House)
