I wish Supernatural belonged to me, but alas it doesn't. I'm merely borrowing the characters.
Ages:
Dean: 13
Sam:9
Carter: 4 months
3:28 am
The clock silhouetted against the dark room. A train rumbled on the tracks outside the motel and legs kicked softly in sheets. Dean blinked a couple times and flicked Sam's hand from his face. The kid snored close to Dean, making him smile; Sam had gradually scooted closer to Dean throughout the night, eventually pushing Dean to the end of the bed.
Carter's legs kicked softly in the sheets, alerting Dean to her presence. A soft coo overcame her and made her laugh. She grabbed her feet and stared up at the ceiling. Her smile grew bigger as her big brother Dean came into view. Forgetting her feet, her hands reached up to Dean's face.
Dean smiled softly, placing his body on the bed and holding Carter's hands in his. "You're happy, huh?" Dean said, gazing at his baby sister. "I don't know why you'd be happy this early in the morning." Sam flipped over onto his stomach, pulling his arms into himself. "Sammy's a deep sleeper, isn't he, Carter?" Carter smiled, showing her bare gums, and strained her head towards Sam.
Dean let go of her hands and pulled her blanket back up. He laid down next to her and gazed at the ceiling. "It's time to go to bed, Carter," Dean said after Carter's hand smacked him in his face. "If I sing, will you go to sleep?" He asked, turning his head to look at her. She stared back at him and cooed.
Dean began, "My mom used to sing this to me when I couldn't sleep." He licked his lips, "Hey Jude, don't be afraid. Take a sad song and make it better. Remember, to let her into your heart, then you can start to make it better."
Dean looked over and noticed Carter was asleep. He smiled and crawled back to his own bed with suction-cup-Sammy.
Thanks for reading! More chapters could be added in a couple days as I'm working on a few more.
