Just try to resist this comical — and infectious — cautionary fable that will have even bedtime-avoiders gladly snuggling up for a nightly challenge.

A yawn can land you in your pj’s and under the covers before you can blink and say "Baa baa black sheep." So clamp your mouth shut and look away from your sleepy dog, stay away from your cuddly blanket, and whatever you do, don’t think of baby orangutans stretching their long arms out for a snuggly hug. Otherwise, you might find your mouth opening wide and letting out a great big yawny yaaaaaawn — hey, you were supposed hold it in! A hilarious read-aloud that is so much fun, kids will beg for it again and again, whatever the consequences.
