A few months ago, I started a new routine to get all of our readings done. I gathered everybody in the girls' room for story time. I have two rules: the babies lie down with eyes closed and the big kids sit quietly while I read.
I do this for naptime and bedtime. I have one book for naptime and a different book for bedtime. (At bedtime, the boys go to their room after I finish the story and there's only one rule- everybody has to sit quietly.)
Not only are we getting a lot more reading done painlessly, but it has really helped settle the babies down. At naptime, I read for about 20 minutes and the babies usually fall asleep while I'm reading. I pick up the bookmark when I get to the last paragraph and that signals the big kids to sneak quietly out of the room.
See that sleeping baby? He passed out before I got to the second page.
