Lullaby by asesina

Disclaimer: I don't own Supernatural. Kripke does. I don't own the song used in the story either.

Summary: Inspired by the mention of "Hey Jude" in the most recent episode of Supernatural. Mary also had a special song for Sam when he was a baby. Set in August 1983.

I hope you like it!

The gentle cool of midnight fell over Lawrence, Kansas, extinguishing the sweltering August humidity that had been plaguing the town for days.

Mary Winchester sighed quietly and soundlessly laid her head down on her pillow. She turned her head to the left and smiled peacefully at the sight of her sleeping husband.

John's soft snoring matched the legato tempo of the lazy crickets and katydids that were singing outside the window.

Mary was lulled into the gentle lassitude of REM sleep within minutes.

Like clockwork, a sharp cry pierced the silence. Sam began to wail in the other room, and Mary's eyes flew open in an instant.

"Honey, what is it?" John mumbled.

"It's Sammy again, John. I'll take care of him," Mary said softly. She patted John on the arm and sat up quickly.

Mary felt around for her slippers and quickly pulled them on.

"I'm coming, Sammy," she said quietly.

Mary rushed down the hallway to the nursery and made her way to the edge of Sam's crib.

"Hi, baby," she whispered with a smile.

Sam's crying tapered off a little, but the wails were still continuous and pervasive.

"Shh," Mary shushed Sam gently. She lifted him into her arms and walked over to the window.

"Look at the moon tonight, Sammy. It's shining for us, honey," she murmured, brushing the top of Sam's head with a ghost of a kiss.

Sam continued to scream, so Mary rocked him back and forth slowly. She walked around the room in a somnambulant waltz, continuing to rock her tiny son as she silently pleaded with him to rest.

"Sammy, you need to sleep. I do too," Mary admitted with a sheepish grin.

Sam still showed no signs of stopping. His face was red with exertion and his cries were becoming shallower and more desperate. It was almost as if he was begging for relief from his incurable exhaustion.

"It'll be okay, Sammy," Mary crooned. She exhaled slowly and tried to think of a song that used to comfort her when she was troubled or upset.

After a few moments, Mary's eyes lit up. She had finally found the perfect song.

"Sammy, I know you'll love this song," Mary said with a wink.

She cleared her throat and began to sing in a smooth, crystalline soprano that floated through the room with a subdued elegance.

"I know it's not much, but it's the best I can do. My gift is my song and this one's for you," Mary began, lowering her head over Sam's face as she paused mid-verse to smile at her son.

He was so beautiful.

"And you can tell everybody this is your song. It might be quite simple but now that it's done," Mary continued, rocking Sam slowly as she continued to slowly circle the room.

Sam's cries were becoming noticeably quieter. He was now emitting a soft whimper, but Mary still had work to do.

"I hope you don't mind, I hope you don't mind that I put down in words," she sang sweetly, cradling Sam closer to her as she reached the end of the chorus.

"How wonderful life is while you're in the world."

By then, Sam was almost completely quiet. He let out a quiet, contented sigh as his eyes closed slowly. He nestled deeper into his mother's arms, and Mary's eyes filled with tears.

"I love you so much, Sammy," she whispered.

Mary kissed Sam's head again and walked over to the crib. She gently laid him down on the powder-blue sheets and cast one last loving glance at her infant son.

Mary Winchester returned to her bed and slept through the rest of the night.

Sam had many sleepless nights after that, but only Mary was ever able to calm him down.

She never did tell Dean or John which song she used to help Sam fall sleep. Mary figured that it would always be their little secret.
