Our 4-year-old twin son awoke the morning and walked into our room, declaring that he had a long sleep. “I went to bed, woke up, and it was day,” he told us.

So, my wife and I proceeded to grab him, place him between us in our bed, and shower him with hugs and kisses. He smiled and laughed.

Then, suddenly, he stopped. His expression became serious. He rose and told us: “I’m going to go get [my twin sister]. She would love this.”
