Author's notes: This chapter has no real spoilers that I know of. I have always wanted to write a fanfic about this so here it is! I will write chapter after chapter starting from Sam's 5th birthday right up to his 6th birthday. I just got so excited at the thought of writing this so I know it's going to be great :) Anyways, I hope you guys enjoy it!

'Then the rabbit smiled and turned to his new friend and thanked him for his help' Dean read and then glanced over the book to check on his little brother. Sam was sleeping soundlessly, much to Dean's relief.

'I hate that book' Dean sighed and put it away. He glanced at Sam with a smile. Dean would die a thousand deaths before he ever admitted it, but Sam did look rather adorable when he was asleep. He closed the bedroom window so Sam wouldn't get cold and covered him properly with the blankets since Sam had kicked them off. Dean was satisfied and then walked over to switch on the night-light. The golden light filled the room, but Dean knew it wasn't too bright because it used to be his before Sam got his own room, which was just a few months ago. Dean turned off the main light and left the door partly ajar before heading to his own room and collapsing onto his bed. Sam had been harder to put to bed tonight because he was so hyped up about his birthday tomorrow. The little kid only got one present a year for his birthday and one card. The present was from Dean and John would get Sam a card. The card was always a cool looking one though and Dean would never give his brother a present that wasn't wrapped. Dean checked his closet to make sure the present was still there, nicely wrapped in blue and red striped wrapping paper. He knew Sam didn't trust closets or cupboards, so he would never find it there. Sam had however, searched through Dean's draws and bedside table. He's tipped his bin upside down and tossed everything out. Sam had been under his bed with a torch for two hours and then pulled everything off Dean's bed in search of his present. The determined child even checked under the rug and in Dean's shoes. After a long day of present searching, he'd settle for some food, cartoons and then he was almost ready for bed. So trying to get Sam to sleep was difficult when the boy wouldn't pick a book and kept asking where his present was. Once he annoyed Dan enough, he would then pick Dean's least favourite book to read.

But Dean knew it was okay once he was able to get to his own bed and sleep. Sammy was only young and as his big brother it was his job to look after him, keep him happy and put up with any of the small, but effectively annoying things Sam did. Or the amount of questions Sam was able to come up with. How that small boy was able to think of a million different questions to ask each day was the biggest mystery to Dean.

Dean yawned and got under the covers. He closed his eyes, finally at peace from his duties as Sam's brother for the time being, at least until Sam awoke him at 7am in the morning…

'Dean!' A scream reached his ears and jolted him awake at once. He got up and dashed to his brother's room. He saw the curtains wide open and the sun was peeking over the mountains. Little Sam was sitting on his bed and reaching for his big brother.

'What is it? Are you okay, Sammy?' Dean asked, now alert and concerned for his brother.

'I'm fine' Sam smiled. 'It's my birthday!' the little boy got up and started jumping on the bed in overwhelmed excitement.

Dean allowed his brain to register that Sam was fine, which meant the earliness of the day crept to his realisation and he then felt buggered. Dean slowly made his way back to bed, but a small hand grabbed him and pulled him back. Dean turned and was hit instantly by Sam's puppy eyes, but they were sad and disappointed.

'Where you going Dean?' Sam asked, his voice soft and excitement gone. 'You s'posed to say Happy Birthday and gimme my present' the boy sniffed and Dean hung his head in defeat, scooping the growing boy into his arms and carrying him to his own room.

'Sammy' Dean sighed. 'I am really tired okay? But-'

'You're always tired' Sam pouted. 'You're no fun'

Dean put him down and told him to close his eyes. Sam squeezed his eyes tight and Dean quickly grabbed the present from the closet and held it in front of Sam.

'Open' Dean said and Sam's eye grew large at the sight of his present.

'It's HUGE!' Sam gasped and sat down with it, staring at it with his big, kid eyes.

'It's not that big' Dean shrugged. 'Open it Sammy'

Sam glanced over at Dean's alarm clock, seeing it was 6:57am.

'I can't' Sam sighed.

'Huh? Why not?' Dean asked.

'You said!' Sam yelled like it was Dean's fault and in Sam's eyes, it was always Dean's fault…unless daddy was being mean. 'You said, I can't open my present until the stupid clock saids it has a seven and then two zeros sitting next to each other' Sam pouted and walked over to the clock. He stood there and stared at it, almost without blinking.

Dean yawned and lay down on his bed, hoping Sam would be occupied long enough for him to catch a bit more sleep.

Sam gasped as the numbers changed but then frowned again when it still hadn't turned 7am. 'Dean!' Sam complained loudly, bringing Dean from his slight slumber. 'Make it go faster!'

'I can't control time, Sammy' Dean replied with his eyes closed.

'Yes you can!' Sam snapped at him. 'You can do anything! Like Superman'

Dean opened an eye to peek a look at Sam. The boy was running around the room with his hands in front of him as though he was Superman and flying.

Sam was making noises and then stopped suddenly. He raced back to the clock and saw he there was a nine at the end and sighed. There was a sound from one of the other rooms and Dean guessed their dad was up now. Sam grinned and ran out of the room with his present.

'Daddy!' Sam ran to him and jumped, lucky enough John caught him and raised him up into the hair for a hug.

'Hey Sam' John smiled. 'Happy birthday' he said and handed Sam a card that was tucked in an envelope.

'Thanks daddy!' Sam smiled as his father put him down; he then rushed to check the time and jumped in joy, as it was exactly 7am. He tore the wrapping paper to shreds and yanked the contents out. It was a box that contained a few books that Sam didn't already have, a blue t-shirt and a puzzle set.

'It's not much' Dean shrugged and wished he could have got Sam a large toy fire truck or something, but Sam seemed to be delighted with his present.

'Thankyou Dean!' Sam hugged his brother tightly and went through the books. There were five in all and since Sam liked books about adventures and animals, Dean had picked ones that resembled that.

'Read me' Sam held up one of the books to Dean.

'Not now Sam-'

'Pleeeease!' Sam pleaded.

'Fine' Dean sighed and grabbed the book. Sam climbed onto the bed to sit beside his big brother while he read him the book about crocodiles.

After Dean was finished, he handed the book back to Sam and sighed at the confused look on his face.

'Um, Dean?' Sam asked.

'Yeah?' Dean replied as he grabbed his brother and led him down the stairs to start getting him breakfast.

'Why didn't the crocodile visit a tooth-doctor when his tooth hurt?' Sam questioned.

'They're called dentists' Dean told him and searched for the lucky charms box. 'And they're a long way from town so um, it was too far for him to walk' Dean replied while John shook his head in amusement. Sam's amount of questions was a mystery to John as well, that boy was just able to come up with so many without even understanding that not everything was supposed to be logical.

'Oh' Sam nodded. 'Then why didn't the crocodile cry when the rabbit pulled his tooth out? When I pull one of my teeth out it hurts and I cry' Sam stated while John tried not to laugh.

'Um…' Dean thought and shrugged. 'Maybe…maybe he was a very brave crocodile?'

'Like you?' Sam wondered.

'Yeah…like me' Dean nodded and placed a bowl in front of Sam along with a spoon.

'Do you think the tooth fairy came for his tooth that night?' Sam then asked and John had to leave the room, it was too much for him to handle.

'Tooth fairy?' Dean frowned in disgust. 'She's not real' he admitted since the last thing he needed was his brother to believe in tooth fairies.

'Is too!' Sam snapped.

'Just…eat' Dean poured some lucky charms into the bowl along with milk. He then pushed it towards Sam and the boy glared at him before finally picking up his spoon and eating.

A few hours later and Dean was finally able to just sit and watched some TV while Sam played with his new puzzle and laughing at his birthday card. John had gone out a few minutes ago but Sam was being more used to it and less upset about his father just leaving them every few days.

'Dean?' Sam looked up at his brother. 'Does dad love us?'

'What? Yeah, of course he does' Dean turned to him. 'He's just got a lot of work to do'

'Okay' Sam nodded and turned back to his puzzle, which he was doing for the 4th time.

Dean sighed and turned back to the TV. The cartoon he had been watching had just gone to an ad break and the moment Dean saw the screen his jaw dropped.

'Sammy, look!' Dean said loudly and his brother turned right around in time to see the commercial for the new Batman movie that had just come out in cinemas.

'That Batman?' Sam asked, unsure.

'Hell yeah, it's Batman!' Dean grinned.

'Okay' Sam nodded and shrugged.

'Sam' Dean said in shock. 'This is Batman! He's the coolest guy in the whole world!'

'Really?' Sam asked, getting excited now. 'In the whole world?'

'Yeah!' Dean said. 'The whole world'

'Even cooler than the Easter Bunny?'

'Ah…yeah, the Easter Bunny' Dean frowned, but then replaced his expression with a grin. 'Even cooler'

'Wow' Sam gasped, having no idea what they were talking about anymore. 'I wanna see him!' Sam yelled and got to his feet. 'Dean! Take me to see him!' he demanded.

'I don't have any money' Dean confessed sadly.

'Grow some!' Sam told him. 'I read story that said you can plant money and it'll grow'

'Sam' Dean sighed, hating to break Sam's excitement. 'Stories are just stories…they aren't real'

'But…why do people write them?'

'Um' Dean searched for the right answer, which Sam always expected him to have. 'Ah, well…because people like to read them, I guess' he shrugged.

'But why?' Sam wondered.

'Sam, I don't know…just, cuz' Dean frowned, sick of always having to know the answer to everything.

'I'm sorry' Sam sniffed.

'For what?' Dean asked.

'For making you mad' Sam told him.

'I'm not mad, okay…I'm just a bit tired'

'You're always tired' Sam pouted.

'Yeah' Dean sighed and turned back to the TV.

Sam sat on the floor quietly for a moment and watched his brother curiously. 'Dean?' he asked, holding up a book. 'Can you read to me?'

By the time Dean had read and re-read many books, he had to find something for Sam to eat. So he heated up Spaghetti O, which Sam loved and then they settled for some homemade birthday cake that Dean had made himself this year. John had gotten all the ingredients and left a recipe for Dean to follow. After that, Dean gave Sam a bath. Sam loved the bubbles and sometimes threw them at Dean, so both boys were sopping wet in less than ten minutes. Dean them helped him dress, before carrying the now-tired boy to his bedroom for another late-night story.

Dean placed the book back where it belonged. He then checked the window was shut, that Sam's blankets were just right and that the night-light was on, before he left the door slightly ajar and wandered to his own room. Dean collapsed onto his own bed and breathed a sigh of relief. Then it was about him. He had his shower and dressed in his own pyjamas. Dean made his way back to his room, but checked that Sam was okay before doing so.

Sam was sleeping soundlessly in his warm bed, clutching a random stuffed toy lightly.

'Happy Birthday, Sammy' Dean smiled and finally went to bed himself…
