Goodnight Moon is a fascinating book. My older child had noticed a few details which I hadn't:

1. The clocks are actually showing the appropriate time as it gets later in the evening.

2. There is a picture, on the wall, of a rabbit fishing, trying to catch a smaller rabbit, using a carrot as a lure. I surely didn't expect the "Why is the rabbit trying to catch the other rabbit. Rabbits don't eat other rabbits, do they?" question.

3. The book on the nightstand is actually the "Goodnight Moon" book itself.

4. There is slightly less "mush" in the bowl after the mouse eats it.
