Celebrate sleep with Dr. Seuss's classic rhyming good-night picture book. Van Vleck, a very small bug, is getting sleepy, and his yawn-contagious as yawns are-sets off a chain reaction, making all those around him feel sleepy, too! With typically Seussian nods to alarm clocks, sleepwalking, and snoring, this charming ode to bedtime will lull listeners (and readers) toward dreamland. Zzzzzzzzzz. This Read & Listen edition contains audio narration.
