It's bedtime, but Ethan isn't tired! Mommy gives him some warm milk, but that doesn't make Ethan sleepy. The two of them watch the fireflies, but that doesn't make Ethan sleepy, either. Mommy tries singing Ethan a lullaby and taking him for a walk, but Ethan is still wide awake. Then, Mommy gets an idea that might be just what Ethan needs to drift off to sleep.
