I point north and tell the time. I sometimes write stories about big boys being babies.

Shit-posting and self-promoting 24/7 😩👌🔥💦🍼
With a whine, you took his hand and let him lead you back into the crowded room, taking wide waddley steps.

With all the chaos, you just hoped somebody paid attention enough to realise the switch. Or at least enough attention to realise you needed a change…
November 29, 2025 at 1:38 PM
“Coming!”

He offered his hand, looking at you expectantly.

“Come on buddy. You don’t want to keep mommy waiting. You’re going to have so much fun eating in the highchair.”
November 29, 2025 at 1:38 PM
“We can say you leaked or something. It’ll be cuter that way. And besides, we don’t want your pretty clothes getting all messy at lunch time.”

As if on cue, you heard your mother call.

“Sweetie? Are you done changing your brother yet? Lunch is ready.”
November 29, 2025 at 1:38 PM
A second nappy quickly followed, hiding the stained padding pressing the warmth and the wetness even closer to your skin. Your brother laughed.

“Wow, they really do suit you. In fact, I think we should send you out in just your nappies,” he said, beginning to dress himself in your clothes.
November 29, 2025 at 1:38 PM
With seemingly practised ease, your brother hoisted your bottom high and slid the padding beneath. After weeks of punishment, he was intimately familiar with the process. With a gentle smush, your bottom came down, as you were taped into your brother’s soaked diaper.
November 29, 2025 at 1:38 PM
You moaned into your pacifier as your brother laughed at you, loud and brash. His old self came back quick. You suspected it never really went away.

“Alright “Baby Mikey”. Legs in the air. Time for your first nappy change~”
November 29, 2025 at 1:38 PM
He ripped his nappy tapes, letting out a sigh as the sodden padding came away, before holding it up for you to see. His face was a Cheshire grin.

“You know, babies spend an awful lot of time in wet nappies. I should know, I was just wearing one. I think it really helps you get into the role.”
November 29, 2025 at 1:38 PM
“I don’t really feel like playing baby today. Too many people around. It’s kind of embarrassing and I don’t really want to miss out on the holidays,” he explained, as he pulled his onesie off. “But don’t worry, it’s actually pretty easy. I think you’ll be a natural.”
November 29, 2025 at 1:38 PM
“L-let me d-“

Your complaint was answered with a pacifier pressed between your lips.

“Hush. Keep that in if you know what’s good for you. We both know nappies suit you more than me.”

Soon, he had your pants down, leaving your little legs bare. Your shirt and jumper quickly followed.
November 29, 2025 at 1:38 PM
With a quick pull, your places switched. In a flash, you felt yourself lifted and laid, your brother now smirking down at you on the changing table.

“H-hey!”

“Easy buddy. You have to be good for your change~”

You flailed feebly as he pulled off your belt, firm grip easily bringing you to heel.
November 29, 2025 at 1:38 PM
“Okay buddy, up on the table.”

The nursery was calm and quiet, away from all the teasing and all the hustle and bustle of the house. Your brother looked at you quietly, before his placid expression finally broke into a smirk.

“Nah, I don’t think so.”
November 29, 2025 at 1:38 PM
No swearing, no stomping away, not even a little pout. You didn’t know how he managed it. You were sure he’d fight back somehow. Not that you were complaining. The sooner you were done with change duty the better.
November 29, 2025 at 1:38 PM
You thought it all might provoke a reaction. He’d been furious when he was first told he’d be diapered for the holidays. But instead, he just sat there placidly, letting all the comments pass him by. He was every bit the behaved baby boy your parents expected him to be.
November 29, 2025 at 1:38 PM
The holidays were no exception. Your parents made sure everyone was well aware of “Baby Mikey’s” new role in the family. Your aunties spent the morning fawning over him, cooing that so little had changed in 20 years, while your older cousins smirked, whispering snide jokes amongst themselves.
November 29, 2025 at 1:38 PM
It was still so strange seeing him like this. He had always been bold and brash, the bad boy to your goodie two shoes. Emphasis on “had”. One night on the booze and a reckless joyride earned your twin him near permanent diaper punishment. Hard to be a bad boy when your mommy still fed you bottles.
November 29, 2025 at 1:38 PM
“Mum says I have to change you.”

You were expecting complaints, but instead, you got obedience. Your brother shrugged and climbed to his feet, following you through the crowded room with a pronounced waddle. Any longer and he probably would’ve leaked.

This is amazing 😵‍💫

Thank you!

Scientist Daddy has lots of experiments he wants to run 🙂

“In this paper, we demonstrate via case study novel methods to reverse key stages in early cognitive development. Permanently…”

“That’s it buddy. Be a good little one and play with your toys while Papa does some writing. You might not have to publish papers anymore, but I do. Everyone’s very excited to read our results.”

He begins to type away, as you remain engrossed in your toys, your mind a world away.
