Sunday, a day of REST?

As far as I know, it was the Lord Almighty who came up with that idea, but when does it actually get put into practice?  In fact, it is the end of the day, and I'm confident I'm more tired than when I started out.  This parenting thing is simply exhausting.  How did my parents make it look so effortless?  But let's be honest, I wouldn't trade it for a billion big ones.  Being Mama Bear is like nothing else in the world.  (In a good way.)
