Recently, though, we switched. At our parish, we always say the prayer to St. Michael the Archangel at the end of mass. I thought including it in our morning prayer would help First Son and First Daughter become familiar with it, so they could recite along with everyone else. We still say our morning prayer, just follow it with this one instead of "Watch O Lord."
Because "Watch O Lord" was a bit long, I didn't expect the children to memorize it, but they had! Kansas Dad usually reads and prays with the older two at bedtime. There's an elaborate ritual involved: one book from each (Kansas Dad is reading snippets from The Book of Virtues
Well, it turns out First Daughter has been reciting "Watch O Lord" as her prayer a great many evenings. It is such a sweet sound to hear her little voice recite the prayer!
