After Four Daughters, My Husband Finally Got the Son He'd Been Begging For – But When He Held Our Newborn Boy for the First Time, His Words Made My Stomach Drop

I nodded, unable to speak. Eight years. Four daughters. And now the son Aaron had wanted for as long as I'd known him.
"Let me get him into a fresh onesie," Rachel said.
Aaron reluctantly handed him back.
She laid the baby in the bassinet, peeled back the swaddle, and unsnapped the tiny gown.
"It can't be."
Then Aaron went quiet.
Not the quiet of awe. A different quiet. The kind that made the room drop ten degrees.
I lifted my head.
"Aaron? What is it?"
He didn't answer. He was staring at the small of our baby's back, at a mark I couldn't see from where I lay.
"I'll be right outside if you need me."

"It can't be," he said, almost too softly to hear. "It can't be, it can't be."

"You asked him to help us."
He turned his head slowly toward me. His eyes were wet, but not the way they had been ten minutes ago. Something in them had gone hard and far away.
"Michael."

I blinked. "What?"
"Michael," he repeated. "All those months I was working late. He was at the house. With you."
None of this made sense.
I stared at him.
"Because you asked him to help us."
Aaron looked back at the bassinet.
"Your son has his birthmark, Elena. The same shape. The same place."
For a second I actually laughed, because I thought he was joking, because none of this made sense.
"He was alone with you."
"Aaron, what are you talking about? He's your son. What does Michael have to do with..."
