Chapter Text
"WaaaaaaaAAAAAHHHHHHH!" Niall cried out, wanting his mommies- Angel and Chloe. They had been keeping Niall and his 'brother' Harry in the closet for a while now. The girls had mentally regressed the boys and made them think they were babies. To the little boys, the closet was their home. It was where they were fed, changed and put to sleep (with the exception of being taken to the bathroom to be bathed). It was also where their toys, blankets and cribs were! Over time, the girls had expanded the closet so they could add more things to it, such a cribs, changing tables and small wardrobes full of cute clothing for the boys.
Anyway, back to Niall crying. He was crying because his tummy was hurting. Niall had drank his last bottle too quickly (which he has a habit of doing), and the milk wasn't settling right in his stomach. It was early in the morning, so Angel and Chloe were still asleep in their bedrooms, dead to the world.
Harry woke up, hearing Niall crying and sobbing into his green teddy bear that he named Nando (for obvious reasons). "Wha' wrong, Ni-ni?" Harry asked tiredly, rubbing his eyes. Niall just continued crying and hiccuping, his tummy causing him so much pain. Harry frowned and climbed out of his crib then went into Niall's. "Ni-ni no cwy..." He gently hugged Niall, Niall whimpering and hugging back. He loved it when his brother hugged him and made him feel special.
Niall sniffled, "T-tu-tummy h-huw-huwts..." He finally choked out, continuing to cry into Harry's neck. Harry cooed sadly, rubbing Niall's back, like he'd seen his mommies do before. He watched his mommies a lot, because he wanted to know how to take care of Niall when they were gone or asleep.
"Shhhhh, it otay, bwuggaboo," Harry soothed, calling Niall by his nickname that Angel and Chloe had given him- Harry's nickname was Cupcake! "I gonna mwake yew awl bettewr!" He bounced and patted Niall's back, the blonde irish boy coughing and gagging. He cried harder, his tummy hurting worse now. Harry frowned, "Shhhhh, shhhh!" He stopped bouncing Niall, and the poor blondie became limp in his older brother's arms, sobbing and wailing, crocodile tears streaming from his eyes and snot coming from his nose. Harry laid Niall down and used his night shirt sleeve to clean Niall's face, then his kissed his nose, which did absolutely nothing to make his baby brother feel better.
"Wha-wah-waaaaaahhhh!" Niall sobbed, holding his tummy and hiccuping loudly.
"Do yew hafta go pottee?" Harry asked, gently putting his hand on Niall's stomach. That's what their mommies always asked if their stomach hurt- did they have to poop? Niall did. Big time. His stomach felt really full and hard, and Harry could feel it rumbling. He looked at his baby brother sadly, hating to see him in so much pain. "I tink yew gotta go poopy, Ni-ni..."
Niall nodded and stuck his thumb in his mouth, sucking it forcefully, since he was stressed out. "Twy pushin'!" Harry said. Niall whimpered and grunted a little, his stomach rumbling loudly and farting a little. Niall was a pro-farter, even as a mental baby. But this one was one of sickness, not like his usual ones made for laughs, so Harry didn't even giggle or snicker at it. "Push agwain," Harry said, gently rubbing Niall's tummy.
Niall pushed and grunted for a few minutes, then it finally happened. He finally started messing his diaper, at first it just coming out in little bits, along with soft farts, then after a few more pushes it all came out. Niall smiled a little behind his thumb and sighed quietly, the seat of his diaper expanding visibly and audiably. He started peeing as well, which made him even more comfortable and relaxed. After a few minutes he finally finished, his diaper soaked and stinky.
Harry laid down next to Niall, "Yewr tummy feewl bettewr now?" He asked. Niall cooed and nodded, kicking his legs gently, his full diaper crinkling. He cooed and cuddled up to Harry, smiling.
"Cupcwake~" Niall cooed, messily kissing Harry's cheek, getting slobber on Harry's cheek. Harry giggled and wiped it away, kissing Niall's nose. They loved each other so much! But Angel and Chloe were going to have quiet a diaper to change in the morning...
