I was watching Season 15 Episode 2 when I got the idea to write this. Takes place when Kai and Nya were kiddos 😊 This is non-canon to the show since I needed Kai to be a good few years older instead of two years older.

"Nya, open wide."

The little girl pressed her lips together firmly as she shook her head. Kai waved the spoon around, "Here comes the submarine! Whoosh- hey!"

Nya giggled as she batted the food off the spoon, watching it drop onto the counter. The spikey-haired brunet groaned as he simply scooped up more baby formula from the cup, "Please, sissy. You gotta have something."

"Sweetie!" She squealed, waving her little fists around in the air, "I want sweeties!"

"You can have some sweets after you have your dinner." Kai's voice was firm as he edged the spoon towards his baby sister's lips. She stubbornly shook her head, standing up on the counter. 

She'd recently learnt how to walk, and it has been a nightmare for Kai since then. Keeping an eye on her was a lot more difficult than he expected it to be.

"Nya! Get back here, you're gonna hurt yourself- no!" He dodged a flying butterknife, catching it by the handle as he set it down, chasing after Nya who was toddling across the countertop, her giggles filling the room.

Since when does throwing knives at your precious older brother count as entertainment?!

"Antonia Maya Smith, get yourself back here right now or no TV for, um...a century!"

Nya simply ignored him, knocking over tins and pots and pans.

"Don't make me turn it into a decade, Missy!"

Young Kai wasn't familiar with the ordering of numbers so he was simply going with what he knew. It clearly wasn't working, however. Nya pranced around the crowded kitchen, dropping jars of unused spices into the sink, "Water go splish-splash!"

Kai rolled his eyes tiredly, "Yes, water goes splish-splash, now will you please get down?" Nya simply cooed as she crawled towards the stove.

"Sis, this is a kitchen, not a jungle gym. If you behave now...I'll take you to the park tomorrow! How does that sound, eh?"

The little girl didn't bother to acknowledge his compromise, slowly edging towards the stove, eyes wide like she was staring at candy.

Kai groaned, slapping a hand over his eyes, "Oh, what on Earth am I gonna do with you, sis?" His baby sister continued to crawl towards the stove, eyes filled with interest. Mind you, it was still hot after Kai warmed up some water for Nya's bath earlier on.

He finally spun around, "Look, if you eat I will- NO NYA, DON'T TOUCH THAT!"

The boy dashed forward, scooping her up at the last minute and carrying her over to the baby chair, strapping her in before returning with the baby food. Nya pouted and shook her head stubbornly.

"Antonia please-"

"Antowia pwease!" Kai blinked as he heard his sister mock him sarcastically in her babyish voice.

"Eat up, otherwise I won't tell you a bedtime story!"

"No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No! No!" She folded her chubby little arms, screaming the house down as Kai stared from the spoon to Nya, back to the spoon.

A light bulb went off in his head, "I'm so sorry, sis," he murmured as he held the spoon up.

Nya continued chanting, just as Kai rammed the spoon into her mouth, shutting her up. The ravenette stared between the piece of cutlery and her brother, whose eyes were filled with guilt. He removed the spoon and gestured at her, "Now chew. Please?"

Just as he thought everything was going well, he cheered.

That is until Nya spat out the remnants onto his face, chuckling at her brother's reaction. 

Serves him right, she thought, clapping her hands hysterically.
