"Aiden, I need a diaper," Jake said with a serious expression on his face. His brother Aiden looked at him, his eyebrows raised in surprise. He thought he had misheard. "What did you say, Jake?" Aiden asked.

"I need a diaper," Jake repeated. Aiden couldn't believe what he was hearing. He tried to explain to Jake that he didn't need a diaper anymore. He was a big boy now.

But Jake was determined. "If we go to the store, we can definitely find one that fits me," he said confidently. Aiden was baffled but decided to humor Jake's unusual request.

At the store, Aiden showed Jake the underjams, thinking they would satisfy his brother's strange desire. Jake, however, was not convinced. "That's not a real diaper, Aiden," he said.

Aiden sighed, scanning the shelves. To his surprise, he found Pampers that went up to size 8. The size 7 matched Jake's weight. Jake's eyes lit up with excitement.

Aiden had to suppress a laugh as they bought the diapers. Jake was so excited, and Aiden couldn't help but find his little brother's enthusiasm endearing.

Once they were home, Aiden helped Jake into his new diaper. Jake was absolutely thrilled, and Aiden couldn't help but smile at his little brother's happiness.

Jake spent the rest of the day happily playing around in his new diaper. Aiden watched him with amusement, shaking his head at his little brother's antics.

That night, as Aiden was tucking Jake into bed, Jake thanked him for the fun adventure. "You're the best brother, Aiden," he said before drifting off to sleep.

Aiden chuckled as he switched off the light, leaving Jake to his dreams. He couldn't help but agree; it had been quite an adventure. And he had to admit, it was nice seeing his little brother so happy.
