At 3:00 in the morning, Laura woke up and gently tapped her husband on the shoulder. "Hector, wake up, wake up!"

"Huhh?" Hector replied groggily. "What is it?"

"It's the baby."

Hector sat up a bit and listened for about a minute. "But I don't hear him crying."

"Yes," Laura replied. "And it's your turn to find out why."
