Oh man, I always read before going to bed, and now I read a bit after lunch but I must take a break after 20 pages and take a small nap. I never thought before that reading might be a trigger for me to sleep.

This is one of those regrets where you aren't losing anything either way - one outcome was that you now have a surefire way of falling asleep.

If it had worked, you'd have a surefire way of massaging your brain with good content. Win-win either way, imho.

For me (not parent) I only nod off if it's fiction and I'm laying down.
