Requested twice by randomrainbow and Shesscertlygorgous16, and I totally spaced for a long time. I am so sorry. Hopefully this fic will make up for that. So here is preteen Sam, experiencing hypothermia. Enjoy!

-----------------------------------------------------------------------------------------------------------------

John sat on the edge of the lake, reading a file on victims for his next hunt, listening to his sons splash around in the water. They were supposed to be working on their swimming skills, but instead they were having fun dunking each other and racing between buoys.

"I so beat you." Sam taunted, as his teeth chattered softly, in the freezing cold water.

"In your dreams, Sammy, I beat you by a whole minute." Dean teased playfully, unaware that Sam's thin body wasn't handling the freezing water very well.

"Pfft, you did not! Dad, Dean is cheating... again!" Sam yelled, wiggling his eyebrows at Dean playfully, even as he shuddered painfully in the cold water.

"Dean, stop cheating. Sam, quit complaining and kick his ass." John grumbled in annoyance, as he pulled his leather jacket tighter against the chilly February air. "Why did you two decide to swim today? I said we could wait a few days for warmer weather." he grumbled, unaware that Sam's shivering was gradually getting worse.

Dean laughed, splashing Sam in the face, and earning a glare. "It's really not that cold, Dad." he argued, as the cold water faintly sent a shiver up his spine.

"It is pretty cold," Sam mumbled softly, shivering even harder in the chilling water. He spit the excess water out of his mouth, from Dean's splash, as his teeth started chattering harder afterward.

"What was that, Sammy?" Dean asked, looking at his little brother curiously. He hadn't noticed until just then, that his little brother was really pale and shivering. "You okay?" he asked, immediately becoming serious.

Sam laughed softly, forcing himself to act like he was fine. "I need to start moving around. Wanna race?" he asked, slurring his s and c slightly. He started swimming slowly towards the nearest buoy, barely keeping his head above the water.

"Sammy, let's go warm up. We can swim more later." Dean suggested, easily matching Sam's speed.

"No, let's race." Sam said angrily, slurring more heavily than before. He shook his head faintly, trying to ignore how hard his limbs were struggling to swim in the water.

His head slipped beneath the water, shocking him with how icy the water felt on his face. He gasped unintentionally, while underwater, and inhaled the icy water. He forced his heavy legs to push his head above the water's surface, choking and gagging on the water he had inhaled.

Dean swam to Sam's side instantly, pulling him above the water and clapping him on the back. "Breathe kid." he said firmly, worried that Sam would aspirate on the water.

Sam gasped softly, wheezing hard as he shivered hard in Dean's arms. "Sorry, I didn't mean to." he admitted softly, slurring heavily.

"Its fine, what happened? You just slid under and came back up gagging." Dean said worriedly, meeting his dad's worried gaze as well.

Sam blinked in confusion, struggling to breathe as the cold felt like his chest was frozen too tightly. "What happened?" he asked, mumbling weakly. He tried to breathe, gasping loudly as he fought to breathe in and out.

Dean frowned. "You tried to drown on me." he said firmly, disapproval heavy in his tone.

Sam wheezed heavily, blinking slowly as he yawned weakly. "M tired." he mumbled, shivering uncontrollably, as he struggled to stay awake.

"Crap! Dad, Sam's sick or something!" Dean yelled, frowning even deeper, as the sudden yell didn't phase his sleepy and shivering little brother.

John frowned deeply. "What's wrong with him?" he asked, grabbing some towels as Dean pulled Sam to the edge of the water as fast as he could swim.

"Difficulty breathing, shivering nonstop, barely able to stay above the water, slurring his words, and he's barely awake." Dean listed off, as he panted after pulling Sam fully out of the water.

"Sounds bad, let's get him back to the motel." John ordered, wrapping two of the towels around his limp and shivering twelve year old.

"Dad, he needs a hospital." Dean argued softly, as he wrapped a towel around himself to try to dry off and warm up a bit.

Sam groaned softly, coughing hard, before losing consciousness in John's arms. His shivering wasn't stopping, even after passing out, he was shivering even harder.

"He just needs to warm up," John snapped, getting ready to load Sam up into the impala.

"Dad, he's sick! Do you want him to die, because we thought he was just too cold?! His lips are turning blue!" Dean yelled at his dad, knowing he was asking for trouble, but it was for Sam, so it was worth it.

"A hot shower and some soup will clear this up." John said with a glare, as he pulled Sam closer to him in an effort to warm him up a bit.

"No, that will make him sicker." Dean snapped, pulling his phone out of his duffle bag that was in the trunk of the impala. "I'm calling 9-1-1, and you need to remove his swimsuit and try to help him warm up slowly." he ordered, not caring if he was in trouble or not. He was pretty sure, Sammy was experiencing hypothermia or something similar. "Make sure he is breathing." he added, worried about how pale Sam was becoming all over.

"Dean!" John roared angrily, before looking down at Sam in confusion. He had never seen his son so pale in his life. "Okay, go ahead." he snapped, as he slowly slipped Sam's swim trunks off, using a towel to hide his nudity.

Dean dialed 9-1-1, frantically waiting for the dispatcher to answer.

"9-1-1, what is your emergency?" an elderly woman's voice asked.

"My little brother, I think he has hypothermia." Dean said numbly, waiting for the woman to laugh at him.

"Okay, hun, tell me what is going on and where you are. Who am I speaking to?" the woman asked kindly, without even a hint of laughter in his tone.

"I'm Dean, but you gotta help Sammy. He's too pale, barely breathing, unconscious, and his lips are turning blue. We are by the lake, by the highway. We went swimming, then he almost drowned." Dean said in a rush, fighting tears, as he watched John start to administer CPR. "He's not breathing! My dad is doing CPR, please, you gotta help Sammy." he pleaded, not caring if he sounded younger than 16.

"Okay hun, an ambulance has been dispatched to your location, just stay on the phone with me until they arrive. You said Sammy almost drowned, was that before the shivering started or after?" the woman asked gently, taking notes and relaying them to the paramedics that were enroute.

"Um... after the shivering started. He started trying to move around, but his legs and arms didn't want to work." Dean recounted in concern, watching anxiously as John continued CPR.

Sam gasped loudly, choking on his own breath and gagging up more of the water he had swallowed earlier. He remained unconscious and shivering, but he had returned to breathing weakly.

"What was that, dear? Are you three alright?" the woman asked in concern, hearing an odd sound when Sam gasped.

Dean nodded, as he started bawling, not realizing right away that he had answered her aloud yet. "Yes, ma'am. He started breathing again, he isn't waking up though." he said worriedly, his voice trembling from the tears.

"It's alright, hun, he is probably going to be asleep for a while, until he warms up again." the woman said kindly, trying to reassure Dean, as the paramedics pulled up.

"They are here." Dean said, trying desperately to be strong now, even as he felt like all he wanted to do was grab Sammy and disappear from this problem and every other one for the rest of their lives.

"Okay, they will take good care of you. Good luck, Dean." the woman said, before hanging up the phone to take another frantic call.

Dean walked over to meet the paramedics, quickly explaining what happened to the driver, as the driver's partner started working on getting Sam responsive.

"Sam, can you hear me?" asked the paramedic, pulling his eyelid up and trying to use a penlight to gauge a response from his pupils. "He is responsive, let's get him to the hospital." she said, as she and her partner carefully lifted Sam onto a gurney and into their ambulance.

"Ride with him," John ordered Dean, as he climbed into the impala to follow the paramedics.

Dean nodded numbly, before climbing into the ambulance and accepting the blanket offered to him as another few blankets were being laid over Sam to help warm him up a bit.

The paramedics drove quickly back to the hospital, with light and sirens the whole way. When they arrived, it was all a blur for Dean, as he lost Sam in the craziness that unfolded.

"12 yr old male, presenting with hypothermia, has already stopped breathing and been resuscitated before we got on scene. His name is Sam, or Sammy." the paramedics rattled off before Sam was wheeled into an area where Dean couldn't follow.

Dean was led to a waiting room, to wait for news on his brother. John joined him a bit later, shooing him into the bathroom to get dressed, and waited until he returned to give him a cup of coffee to his eldest.

Hours passed, patients came and left, before a doctor finally emerged looking for John and Dean.

"Family for Sam or Sammy?" the doctor called firmly, looking for anyone to answer.

Dean was on his feet first, closely followed by John. "We are. Is he okay?!" he demanded, practically pouncing on the doctor.

"He is going to be fine. No limbs, toes, or fingers were lost. His heart did give out twice while we worked to warm him up, so we will need to keep him here for a few days to make sure he is a-okay. He was also given antibiotics, as the near drowning gave him a touch of pneumonia, but we caught it early so he will be fine. Would you like me to have two cots set up in his room for you?" the doctor asked, looking more than a little tired.

"Yes please, can we see him?" John asked simply, relieved that Sam was on the mend.

"Yes you may, he is heavily sedated and will remain so for a couple more days." The doctor warned kindly.

John and Dean nodded, knowing that the sedation would help Sam heal better than normal resting would. They were ushered into Sam's room, both relieved to see that there was a bit more color to the youngest Winchester's face than had been the last time they saw him.

----------------------------------------------------------------------------------------------------------------------

It took a week and a half, before they were told Sam could go home on light work load. He did end up sick with pneumonia and bronchitis, but healed up nicely within the next month.

"No more swimming in February." became John's new motto, and was crammed down Sam and Dean's throats for months and years on end. 

I hope you enjoyed this fic, I tried to keep it as medically accurate as possible.
