Tim stirred awake after an admittedly very nice nap. What greeted him was the shadowed light that fed in through the crib bars, which was always an immediate reminder of his strange and frustrating situation. Due to an accident involving quantum particles Tim found himself miraculously in a younger body, though his mind remained the same, which meant his treatment was all the more humiliating to him. The nursery that was his room was for someone even younger than the body he now accommodated, but his body continued to frustratingly fail him and prove that it needed such a room. As Tim stretched and really started waking up, he could feel the dampness of the wet diaper, held up by the dinosaur printed onesie he was still wearing from the outing earlier. The onesie kept the now sagging diaper in place, but it also pressed it against him and was a constant reminder of his current state.

Now that he was awake, Tim’s new goal was to escape his comfy confinement. As Tim stood up in his crib, he let the pacifier he didn’t realize he was suckling on fall out of his mouth, getting caught on the pacifier clip attached to his onesie. He then carefully sat down the stuffed teddy bear he didn’t realize he was cuddling. He looked at the thing with a bit of disgust that was really directed at him. Was he really using his pacifier while he slept? Did he really need to cuddle that bear to get to sleep? Was any of that worse than the fact that he had wet himself while he slept? Tim’s condition was seemingly getting or worse, or maybe he was just falling into the role he was being forced in to.

Tim gave a fruitless attempt at opening the crib himself. He knew how to operate the mechanism holding the bars up, but it had been frustratingly just out of reach. Tim’s body did not grow enough to reach it during his nap, though he still tried. Having once again been met with failure Tim fell back down, squishing in his diaper as he did.

“Aunt Lisa!” Tim called out.

“One minute sweetie,” A voice came in quietly from the living room. Tim knew from experience that Lisa would not be in a hurry to get him out of the crib, so he put the pacifier back in his mouth and started idly playing with the stuffed bear as the two things were his only forms of entertainment. Eventually Lisa did deign to come in to let Tim out.

“There’s my little baby,” Lisa said cooing down at Tim in his crib.

“You know I’m not actually a baby, right?” Tim said as the pacifier again fell from his mouth and hit the bear he was holding. “This body isn’t even a baby.”

“Uh-huh,” Lisa said in a way that said she obviously didn’t believe him. She effortlessly lowered the crib bars and motioned toward Tim. Tim entered her arms and allowed himself to be picked up as Lisa grunted. “Oh, someone’s wet. What was that about not being a baby?” Tim just grumbled as he was placed on the floor and had his onesie opened so Lisa could inspect the diaper. “You can hold more though,” Lisa said matter-of-factly as she snapped the onesie closed again.

“What!? But… Lisa. You can’t just leave me in a wet diaper like this.”

“Oh, don’t be so fussy,” Lisa chided. “You know diapers are expensive and changing you takes time. I’m sure you’d rather get to playing.” Tim pouted and rolled his eyes. Lisa always had a way of technically being right in these arguments. Tim did feel a little bad that his aunt was spending so much on his care, though she seemed to be enjoying it. He also really would rather get to “playing.” Playing in this case meant being left alone for one thing, but Tim was also eyeing the toy chest where his lap top rested atop a series of more juvenile toys.

“Yes, aunt Lisa,” Tim said slowly. This time Tim was playing Lisa a little. Answering back in a deliberately over obedient way so he could be left to his own devices.

“Good boy,” Lisa playfully patted Tim’s diaper. “I’ll let you get to playing. Your auntie has some things to do. Yell if you need me, ok?”

“Yes ma’am,” Tim waited innocently until his aunt left the room. When she did he immediately jumped to the toy chest and uncovered his prize.

Tim’s laptop was a thick black machine decorated with stickers from several nerdy sci-fi shows and anime that Lisa probably wouldn’t let him watch if he asked. It was one of the few remaining relics of who Tim really was: one of the foremost researchers of quantum mechanics. Quantum mechanics was Tim’s goal for this excursion into the internet. He logged into his college’s portal and got to perusing multitudes of articles on the subject, wondering if anyone had published any results from the experiment that resulted in his current state of regression. He didn’t find any, which wasn’t totally surprising. The results of that particular experiment were carefully guarded for good reason. With no ground gained on that avenue, Tim turned to browsing articles in general. Not only was it his particular passion, but he found it uniquely stimulating in his current predicament. It reminded him that he was still him. Despite all evidence around him telling him he was a baby, the fact that he could read, comprehend, and enjoy these highly detailed articles examining the fundamental forces of the universe meant he was still an expert in his field.

“What are you up to little one?” Lisa had interrupted Tim’s browsing.

“Just some light reading,” Tim answered not looking up from the laptop.

“Light reading for almost two hours. Come on that’s enough screen time,” Lisa picked up Tim who fussed and made grabby hands at the laptop.

“No! Lisa, I was reading that!” Tim complained as he tried and failed to escape his aunt’s grasp.

“Too much screen time is bad for little ones.”

“Those were academic articles, It’s educational material.”

“Don’t be angry just because you can’t play with your toys.” By this point, Lisa had carried Tim into the living room and made her way to a baby bouncer situated next to a recliner in a corner of the room. It was a pink chair suspended on a metal rig with stretchy cables. A circular tray dotted with baby toys went around the whole thing. Tim’s body was just barely able to fit in it, but fit in it he did as Lisa deposited him in the contraption.

“This should give you a little exercise,” Lisa smiled. Despite Tim’s best attempts, he couldn’t escape from the contraption. He couldn't get the leverage needed to move his legs out of the leg holes in the seat. The attempts only served to bounce him around. Eventually he wore himself out and just sat back into the chair in defeat. Despite not actively flailing any more the device still lightly bounced him at any small movements.

Boredom set in for Tim pretty quickly. Lisa, having had her fill of cooing at Tim as he bounced in frustration, had moved to the kitchen to prepare dinner. She felt like Tim was safe enough in the bouncer, and she was right. With nothing else to do Tim resigned himself to the humiliating distraction of playing with the toys on the bouncer. With the pacifier in his mouth Tim batted away at a round rattle, fiddled with a wooden toy, and squeaked a noise maker. Even though she couldn’t watch closely, Lisa smiled at hearing Tim play.

“You having fun over there baby boy!” Lisa shouted teasingly. Tim sighed loudly and pouted which made him bounce even more. “So stinkin cute,” Lisa said having been able to see that particular bounce.

Tim was frustrated at himself. This was just one in another series of interactions where he had unintentionally encouraged his aunts babying behavior. Whenever he tried to fight against it, it was dismissed as being fussy so it just made him look more like a baby and further encouraged his aunt’s antics. He was really stuck between a rock and a hard place. Or a baby bouncer and a crib in his case.

“Ok little one I’ve got din din all done!” Lisa sang happily from the kitchen. “You ready for some nummies?”

“I have gotten hungry yes,” Tim responded as maturely as she could.

“Mmhmm got all hungy playing in your bouncy huh?” Even when he was trying to be mature his aunt filled in childish dialogue for him. “Let’s get you out of there.” Tim eagerly raised his arms up and Lisa picked him up with a grunt balancing him on her hip.

“I could have walked,” Tim complained.

“Oh, don’t be so pouty I need to get you in your high chair anyway.”

“I don’t need a high chair.”

“You let me decide that,” Lisa said playfully. As she spoke, she pressed against Tim’s onesie. “Sweetie did you have another accident?”

“I didn’t … I don’t,” Tim stammered in shock.

“Oh, you definitely did,” Lisa said running a finger into Tim’s diaper. “No wonder you’re so squirmy.”

“I didn’t even notice,” Tim said more to himself than to his aunt.

“Well, that’s why you’re in diapers sweetie. Now let’s get your belly full so we can get that diapee changed.”

“I can’t get changed before dinner?" Tim complained though he was already being sat into the high chair.

“A hungry baby is fussier than a wet baby,” Lisa said snapping a wooden tray over the high chair and once again trapping Tim. “Plus it’s good motivation to get you to eat all of your food,” Lisa tied a pink bib around Tim’s neck. Tim grumbled at the whole situation while Lisa sat a plate of dinosaur shaped chicken nuggets, mac and cheese, and a baby bottle of juice on the high chair tray. “Now ready to open up for the dinosaur.”

“Lisa,” Tim whined. “Look I’ve been perfectly well behaved all afternoon. I let you put me in the crib, the bouncer, and this high chair. Can I please just eat this by myself?”

“I would disagree on you being well behaved.”

“Pleeeeeaaaaassssssse,” Tim whined again.

“Ok ok my big boy,” Lisa quickly grabbed a child’s fork and sat in on the tray. “I’m here if you need help.”

“Thank you, Lisa,” Tim sighed in relief. It wasn’t much, but Tim appreciated this small bit of maturity he was allowed. He would also have like to have had the parmesan chicken Lisa had cooked for herself instead of the kid’s food he had been given. With the afternoon he’s had though, he would take the small victory.

Despite being childish, the simple meal was really hitting the spot. Tim pondered that maybe his taste buds might have regressed with his body which is why the childish food tasted so good to him. He finished quickly. Lisa was still eating and watching tv so Tim moved on to the bottle of juice, suckling away.

“All done?” Lisa’s voice actually came as a shock as Tim had gotten oddly focused on his bottle.

“Uh, yeah,” Tim sat the bottle on the tray while a small blush came across his face.

“Good boy, you made a happy plate!” Lisa congratulated as she took the plate and kid utensil from Tim and stashed it in the dishwasher. “And with only a little bit of a mess,” she said as she wiped a small bit of sauce off of Tim’s cheek with his bib before removing it. Tim waited expectantly while Lisa finished giving her own plate a quick rinse, but his anxiousness was starting to show as he kicked his feet in the high chair.

“I know sweetie I know,” Lisa said sympathetically. “I bet you are ready for a diapee change huh?”

“Yea please,” Tim said with a hint of frustration.

“Ok,” Lisa said as she removed the tray from the high chair and picked Tim up again. “Let’s take care of that. You’ve been a very good boy for being patient.” Lisa handed the bottle back to Tim and he immediately continued to suckle juice out of it while he was carried back to the nursery. By the time Lisa was laying Tim down onto the changing table and securing him in with the chest strap, the bottle was empty. Lisa had expertly swapped the nipple of the bottle out for the nipple of the pacifier before Tim could become upset about it. Of course, Tim was a little annoyed at the whole thing because not having a nipple in his mouth for two seconds wouldn’t have made him that upset, but Lisa was still proud of her expertise.

“See isn't your auntie such a good caretaker. Can't have little baby being getting upset at an empty bottle so we gotta get that paci in fast," Lisa playfully booped the soother that Tim was busy suckling. "Now what are we thinking? Bunny diapees or bear diapees?” Lisa held up two different diaper prints up to Tim. Tim honestly didn’t care which of the embarrassing prints he would be stuck in so he pointed at the bear print without even looking. “You sure you don’t want bunnies?” Lisa asked hopefully. Tim rolled his eyes and moved his finger from the bear print to the bunny print to satisfy Lisa. “Yeah bunnies,” Lisa smiled. “Good boy.”
