Amy pulls him along as they walk to the living room, yelping when her arm is suddenly jerked back. Stopping, she looks back to see Sonic fidgeting in place with a worried look in his eyes, anxiously whispering, "Um, Amy...don't you think I should-um...doesn't something seem off to you?"

Tilting her head, she looked him over. Nothing seemed out of the ordinary, his diaper obviously needed to be changed, but other than that, everything seemed fine to her. It was Sonic's demeanor that was off like he wasn't comfortable in his own fur. He'd been acting strangely for a while, especially around Amy and Shadow, having a fleeing look in his eyes and acting antsier than usual. She'd gotten the impression at times that he wanted to be with them as little as possible.

Her thoughts drifted back to what Shadow had mentioned yesterday. Why is Sonic so closed off now? He had opened up so much about his past to us, and after that, we grew so close, spending so much time together since the incident. (Well, not incident more like a happy accident almost two months ago.) What's changed? Sonic closed them all off again as soon as he got back to normal...why? He was safe with them. Why did he seem not to want to be in their company anymore?

"No. Why? Do you need a change?" she asked, puzzled. Sonic's face flushed, and he started to sweat, "N-no! Of course not! I didn't use the stupid diaper! And what am I doing with one on anyway?! The guys will never let me live this down if they saw me like this!" he stuttered, gesturing to the padding with gritted fangs.

'The guys would never live him wearing a diaper down?' She was taken aback by that statement. The guys have never made fun of him wearing one before. Why would they do so now? A light bulb started to flicker in her head, an idea of why the blue blur was acting so strangely. She would need to talk to Tails first, hiding her confusion behind a gentle smile. Amy retook his hand, guiding him again to the rest of the group, "Don't worry about it; they don't mind if you're in a diaper. They know already. But we do need to talk, so just relax, and I'll fix you up later." leaving him with no opportunity to argue, she pulled him forward, calling out to everyone. "Hey guys, look who's up!"

All heads turned to them with smiles of relief, "Welcome back, blueberry!"

"Sleep good little blue?"

"Feeling better, Sonic?"

The blue hedgehog gaped at his friends, red-faced too embarrassed to say anything; his lips pressed tightly behind silent whimpering. "He's okay," Amy answers, gently pushing him down to sit on the couch; Shadow and Tails scoot over, giving him room, "just a little confused."

"Oh?" Knuckles raises an eye ridge, "Don't worry 'bout that. Happens to me all the time. It'll pass." he assures; Sonic rolls his eyes, his snarky composure returning briefly to reply with a dull sarcastic tone, "Gee, thanks, Knux, real helpful."

"You're welcome!"

"So you're feeling ok now? I wouldn't be surprised if you were still tired after going 4 days without sleep." Tails asks, crossing his arms with a look of disapproval. Sonic sighs, rubbing the back of his head, bashfully reminded of his actions over the last few days, "Oh, yeah, I'm still tired. But I feel much better than yesterday. Though those darned dreams still won't go away." he lowly coughs the last part behind a gloved fist.

Suddenly Amy reappears, having left for a moment to grab something, "Here, drink this." she offers, "Oh, thanks." he smiles at her, feeling quite parched. When he sees the drinking vessel, a baby bottle of apple juice, he glares at the bottle like it was mocking him, "Ok. Enough, I've had it! Seriously, what's the deal!?" he yells, shoving the thing back into Amy's hands.

"What are you talking about?" Shadow asks with raised brows. "This! All of this!" Sonic flails his hands to the bottle, and all of them getting increasingly frustrated, "You guys have been treating me like a little kid for weeks now, and I'm sick of it! What is this all some sort of elaborate prank? Look, whatever I did, I'm sorry I won't do it again but knock it off!"

All in the group look at each other, confused at first as to what their blue leader was talking about. They sweatdrop, having the decency to look slightly ashamed even if they didn't know why. "Sonic, this isn't a prank." Shadow says meekly, leaning closer to the blue hedgehog, "I can assure you we were not doing it to antagonize you. I don't think we even realized we were treating you that way. We only did so out of habit."

"Habit?! Since when did this become a habit?!" Sonic continued to yell, "You guys never treated me like this until a few weeks ago."

Amy tapped Tails' shoulder discreetly, flicking an ear her way, he whispered, "What is it, Amy?"

"I think I know what the problem is." Tails tilted his head to her. His attention drifting away from the upset chattering hedgehogs beside him. He indicated for her to continue, "Sonic's lost his memory."

"You think he has amnesia? What makes you say that?"

"He looked very confused and lost when I went to check up on him in the nursery. And he obviously used his diaper. You'd think since I've changed him in the past, it'd be no big deal now, right? But when I asked him about it, he flat out denied ever using it. He was more concerned about what you guys would think seeing him in it. And you saw the way he reacted when I gave him the bottle-uh purely out habit, mind you!" she whispered.

Tails pondered what the pink hog told him and, thinking back to what Shadow had mentioned about his brother's behavior and what he had seen himself. It seemed to line up with what she said. Though it was possible, there could be another explanation for the odd behavior.

"Sonic..."Tails spoke, tapping his brother's shoulder, interrupting the two male hedgehog's conversation. Both turned to the young fox, who started to whisper in Sonic's ear, "Have you been...repressing your ABDL tendencies?" The blue blur shook his head, taken aback, staring at his brother like he had lost his mind, "My ALD, who what now?"

"Do you remember what happened last month when we went to those tunnels Amy had us explore?" Tails pressed out loud, "The underground tunnels? We never went there. I thought we canceled that trip?"

Blue eyes lit up in understanding. Amy was right; it all made sense now. The distancing, the forgetfulness, and other odd behaviors (besides the refusal to sleep, he still didn't know what that was all about) were all connected. Sonic had selective amnesia.

"What? Yeah, we did! Don't you remember Sonic? That's when you turned into a little teeny tiny baby." Knuckles replies narrowing his eyes and the distance between his hands, illustrating how small the hedgehog used to be. Sonic just stares at the echidna in bewilderment. Shadow was doing the same but at Sonic before both gaze back at the fox. Folding his hands together, Tails shyly smiles, "He's right."

"What! But...but-" feeling out of the loop, Sonic quickly glances at Shadow and Amy both nodding their heads confirming it was true, "But I don't remember anything!"

"That, " Tails timidly points to himself, looking away, "Is my fault." Shadow glares at the fox kit dangerously growling, "What did you do?"

"It wasn't on purpose, I swear!" Tails put his hands up in a placating gesture, desperately hoping Shadow wouldn't kill him, "I just may have...forgotten to make an adjustment to the formula used to turn him back to normal." he squeaked quickly. Sonic's eyes flicker back and forth from Tails and Shadow. This wasn't making any sense. Pulling his ears down in frustration, he yells, "Will somebody, please explain what the heck happened to me?!" His younger brother lays a hand on his knee, "I'll explain. Ya see..."

Tails starts the tale from the beginning with how Sonic had discovered a youth regeneration machine in the tunnels, getting accidentally stuck inside and turned into an infant. Shadow and Amy cut in at certain points in the story before taking over completely about Sonic's time in their care. Knuckles even adds in specific details or forgotten points during the story.

As they continue, Sonic's face morphs from confusion and anger to sadness, and recognition, calmly nodding, taking everything in, not interrupting even once. He recalls the events as they are told, remembering everything he felt and thought about from that first day to the last moment before returning to normal. He also realizes that the dreams he had been having weren't dreams at all...they were memories.

Waves of remorse, regret, and grief wash over the hedgehog, his head falling slowly into his hands with a flush, trying to hold back the tears, feeling ashamed of the way he had foolishly behaved toward his friends, blaming them for the way he had been feeling. When in reality, he was the one to blame. At the end of the story, Sonic's eyes are closed, hiding his tears behind closed fists, and his shoulders shake as he silently breaks down.

Before anyone can stop him, Knuckles with a speed that would have impressed Sonic; we're he not in emotional distress, knowing the signs of a crying hedgie. Throws himself up, grabbing the sobbing hedgehog off the couch and into his arms. Taking his place on the sofa, keeping a spiky blue head over his broad shoulder, Knuckles held Sonic in a protective and comforting hug. Sonic instantly latched on, Knuckles tightening his hold in return. He didn't look like he was going to let the hedgie go anytime soon.

That broke the dam. Sonic wept harder, wrapping his arms around the big brute, having not felt this small and vulnerable since before turning back to normal. It was so nice, warm, familiar, safe. He felt a wave of nausea hit him, feeling sick at how bratty he had acted days ago, knowing he should have just confronted his friends about the situation instead of trying to tough it out and fix it himself like he usually did. Things never worked out well when that happened; only then he opened up about his problems did things turn out. That was the real issue, not opening up; it only brought him pain and heartache like right now.

Seeing him burst into tears, Amy and Shadow quickly turn into parental mode taking their positions, surrounding the echidna holding the sobbing hedgie in their embrace, "I'm sorry, I'm so-so-sorry. I should have told you, I should have-I'm sorry," he cries quietly repeating. "What on Mobius for? It's not your fault you lost your memory." Amy says, rubbing circles on his back, "B-but-but I did! And I mistreated you all when I started remembering." Shadow blinked, not sure if he had heard Sonic correctly, "You-you remembered?"

"Y-yeah, in my dreams. That's why I was trying so hard not to fall asleep at night." he shudders, taking a few deep breaths to calm down enough to talk; he sniffed and continued, "I remembered how you guys took care of me. The way you treated me was so...nice. I felt so loved and not just needed but wanted." Sonic choked out a bitter laugh, "But then whenever I woke up, and you guys weren't there. I felt...so alone and ashamed of myself for having those kinds of, what I had thought of the time, dreams, and wishing that they weren't. That you guys were-we-" at that, he broke down again. Covering his face in shame.

"I'm so sorry, guys," he croaked some minutes later, his voice raw from crying so much. "I-I should...I should have told you what was happening. I should have told you the truth."

"It's alright, little blue, " Knuckles says, rubbing circles in between blue spines, "we forgive you."

"N-n-no." Sonic hiccups, "It's not ok. I need to come clean." steeling his courage and taking a deep breath, Sonic turns himself around in Knuckles' arms to face his friends, explaining a side of himself that had appeared during his one-month baby experience. He tells them about how Tails discovered he was having a second childhood through one test during the first few days and learned that he was an Adult Baby. And how he had secretly explored his Little side during his time as an infant.

"But I was too afraid to tell you guys, letting my pride get in the way again. I was too embarrassed that when I'd turn back to normal, you'd think I was nothing more than just...a pathetic little baby...instead of a hero. When that's what I am really-sniff-just a big baby. I'm so sorry you guys for lying and not telling you sooner, and even though I still at times want to be treated like a baby or toddler, you guys don't have to. You've done enough of that for me already, and I can't thank you guys enough for being there for me when I needed help."

"It's ok, Sonic, we forgive you! And we would do it all again in a heartbeat!" Knuckles chirped, petting the hedgehog's quills. Shadow took his right hand and gave it a squeeze, "Thank you for telling us that, Sonic. I know it wasn't easy, but...why would you think you couldn't be your Little self around us anymore?"

"Ah, we-we'll-cause I'm not a baby anymore, I'm-" Sonic's ears lowered as a look of forlorn appeared in his eyes, "I'm all grown up now. I'm not little and cute anymore. I'm supposed to beat up bad guys and be cool and tough. Not a cry baby that needs his stuffy and bottle."

"Who says you're not cute!" Amy gasped in mock offense, tapping her finger on his black nose, making him go cross-eyed, "And you definitely are a hero. As many times as you've saved this village, you have every right to be called a hero." using her thumb, she wiped away a few stray tears as the beginnings of a smile formed on his muzzle. "You mean...it's ok if I use diapers, play, and act like a baby in front of you guys?" Sonic asked with a quiet voice.

"Of course!"

"Absolutely!"

"I have no problem with it!"

"I like you as a baby!" Everyone happily consented. "In case you've forgotten, we've been babying you anyway!" Amy laughs at Sonic's forgetfulness, "Oh, yeah. Heh, I was just complaining about that, wasn't I?" he blushes, shrinking into Knuckles and rubbing an arm. Amy smiled lovingly, "Together, we're a family, and you are our blue baby! Don't you remember what we told you?" she asked, taking his other hand. Emerald eyes filled again with happy tears; Sonic sniffed cheeks flushed brightly, the ends of his lips wobbling into a faint smile. Turning to look at Amy and Shadow on each side, "Y-yeah...that I'm your baby a-and that you'd guys wouldn't leave me alone?" Shadow and Amy grinned, squeezing Sonic's hands a moment in pride. "That's right! And don't you forget it!" he lowered his head, guiltily, "But...but I did forget."

Shadow's brows perked, "And what did I say would happen if you did forget?" Sonic's eyes widened, pulling himself closer to Knuckles trying to hide a smile. Shadow raised his free hand, flickering his fingers before reaching under the blue hedgehog's exposed belly. Sonic shrieked, breaking into a huge grin, taking his hands back to swipe Shadow's hands away, trying to get him to stop but not trying very hard, laughing and squirming.

"Ahahah! D-daddy! St-hahaha-stop!" pulling back, Shadow snorted, quitting his tickle attack, happy to see his little blueberry back and smiling again. Everyone else chuckled along; Sonic cuddling in Knuckles' heaving sides, feeling once again like a weight had been lifted from his shoulders; all was forgiven, his friends accepted him, and his stomach bubbled in happiness.

Knuckles smiled widely, bouncing the hedgehog in his arms, "Feeling better little blue?" Sonic quirked a smile back, ears all a tingle hearing that nickname, "Yeah." he sighed. His ears lowered back down, looking at Amy shyly; he felt the need to slip back into his little space. It had been far too long, in Sonic's opinion. But getting back there comfortably again around his friends would take some time, baby steps, and the first one was always the hardest. But he was safe here, they were ok with it, and there was no time like the present. Gulping, Sonic shrunk a bit, asking in his childish voice, "Um...mo-mommy?" watching her eyes light up, Sonic continued a little more confidently, "Can I has baba...and Speedy?"

"Of course!" she smiled, handing him his bottle; she left to go find the plushy for him. "Wait!" she halted, "Where is Speedy?"

"At my house." nodding, the pink hedgehog quickly left to grab the stuffed animal. After she left, Sonic looked to his brother, "Ahum, Tails..."

"Hmm?"

"Thanks for all of your help with this...and for putting up with me." he winked, smirking; the fox winked back, "Anything for you, bro."

Amy returned in record time not only with the toy but also his paci, but she held back from giving the items to their owner, "Here Knuckles, I can take him now." she extended her arms. "You sure?" Knuckles asked his charge for permission, not knowing why Amy wanted him. Sonic looked back at his large friend, shrugging but nodded in approval. Knuckles handed Sonic over to Amy, "Thanks. Come on, let's get you changed.~" she chimed; he blushed, forgetting about his soggy diaper. Cuddling Speedy, he drank his juice while Amy took him back to the nursery.

Turning the lights on, she laid him down on the changing table; Sonic giggles as she removed the diaper, holding his plushy tight, feeling the cold air hit him. Smiling warmly, she cleaned him up and pulled out a new diaper, "Mommy?"

"Yes, baby?" Tilting his head, emerald eyes bounced between the room and Amy asking curiously, "How come you didn't put away the stuff in my nursery?" Jade eyes saddened a little before brightening again, "Well, I was going to after you got back to normal and Shadow left. Since we wouldn't need all this stuff anymore...but...I-I just couldn't bring myself to do it. There were too many good memories here." he beamed at her, smelling the baby powder, eyes shining brightly, "You missed us?"

"Yeah, I did." Amy grinned, wrapping him up in the new diaper covered with bright sunflowers as she watched him yawn widely. "Someone's still a sleepy boy.~" she hummed; Sonic nodded, trying to keep his eyes open. She laughed softly, picking him up and placing him in the crib.

Narrowed eyes looked at her, confusion written all over his tired face. It was so cute, Amy was ecstatic to have her blue baby back. Tucking him in, she turned the mobile on and placed the paci in his mouth. Making sure the half-empty bottle was within reach and Speedy was in his arms, she caressed his cheek and kissed his nose and forehead. "Get some sleep, sweety. You've had a long day." smiling, he sucked the pacifier, "Nighty-night Mommy." he mumbled, "Nighty-night my little emerald." she whispered, turning off the light and closed the door.

Sonic breathed out through his nose, stifling another yawn. Heart glittering and swelling with love, he cuddled Speedy closing his eyes to dream of playtime, bottles, diapers, and all the other things that made his little self glow with joy.

*A note from the author*

I just wanted to say thank you so much to anyone reading this story! I've been in the STH fandom for almost a year now, and it is my first time writing fanfiction.

When I started falling down the rabbit hole, that is, the amount of STH fanfics available out there, I found a few baby Sonic stories and fell in love with the ideas! For the first time, I also came across ABDL stories and realized after some research and intense self-examination that I am a Little myself. With the plethora of ideas and head cannons out there, I found myself brimming with story ideas for fanfiction, something that had never happened to me before—originally coming from a small fandom.

I'll admit when I started writing this story and decided I would post it, I was certain that a majority of the comments would be hate-filled, and the story would receive very few likes. But you guys have proved me to be very wrong. I've been floored at the amount of likes/ hearts/ kudos/ support and positive feedback you'll have sent me and couldn't be more tickled!

And I think you'll be happy to hear that I plan on posting more Sonic ABDL stories in the future! As of writing this letter, I'm working on my next story. "A Little Contract." The story will focus on Modern Sonic moving in with Eggman, and the Little shenanigans that ensue shortly after, along with some conflicting feelings, don't worry. No shipping will happen. That's not really my scene, especially where Little/ABDL things are concerned.

Someone asked me a while ago if I planned on doing any oneshots with this story. And after some consideration, I think I will! I don't know when I'll get to work on them, maybe while I'm writing "A Little Contract" if I need a break or if it'll happen sometime after that story is finished. Either way, I already have a few ideas. However, I haven't come up with very many, so if you have any ideas or suggestions, please send them to me! Though keep in mind the one-shots will be focused on Boom Sonic! and your ideas suggestions may or may not come to fruition as it all depends on how well I can flesh out the idea in my mind. Also, I will absolutely not writing anything kinky, erotic, lewd, or shippy!

Just...NO!

Here are a few prompts I have for the one-shot series so far;

Sonic visits Mom-bot for the weekend.

The team goes for a swim at the local watering hole.

Sonic is sick.

Eggman makes a baby ray, but it doesn't quite work.

Shadow wakes up to find Sonic upset from a nightmare.

Mark the Tapir returns and starts spying/stalking Sonic.

Sonic is depressed.

Anyway, that's all I've got so far. "A Little Contract" chapters will start to be posted on Valentine's week in celebration of when the Sonic movie came out and when I officially became a Sonic fan! 😆 Until then, feel free to check me out on Tumblr: ravecole or Deviantart, where I go by theeccentricnomad and post drawings to go with certain scenes in the stories. Don't expect too many in the next story as I can't draw Eggman yet. 😝

Shout outs go to the-pixlexic-sloth, my dear friend who has been so supportive of me dipping my toes into writing fan fiction and accepting my Little self.

Also, sargrasso8, blackpaw2020, babybubbled, guardiandragon98, terrabyte, shizu6616, saki, and everyone else who left comments. I can't help but giggle like an evil villain every time I see one! 😆😈
