"Ah, Sundays. A time of the week where the Loud House isn't so loud. Most of us take the time to laze around, sleep in, and just do nothing. But not me, because Sunday is the one day of the week where it's just me...and Lily."

Lincoln looked into Lily's crib, where its occupant was sleeping soundly. he whispered her name into the crib to wake her up. After a few tries, she yawned, rubbed her eyes, and looked up at her big brother above her.

"Good morning, Lily! Are you ready for our special day?"

The baby smiled and squeed in delight. Lincoln lifted her out of her crib, and the fun started immediately.

"Time for liftoff!"

Lincoln made rocket blast noises and he ran around carrying Lily love his head. He ran through the halls as Lily partook in the illusion of flight. When they made it to the starway, Lincoln sat down and placed his baby sister by his chest.

"Hold on, Lily! He we go!"

With a push, Lincoln bounced down the steps on his butt, with his and Lily's shouts being rendered staccato as he did. When they reached the bottom, the rocket trip resumed until they made it to the kitchen. At that point, Lincoln sat Lily down in her high chair and got some special pudding from teh fridge.

"Here you go, Lily! Rainbow pudding, made especially for you."

Lily giggled at her unusual pudding, and it made her all the more eager to eat it. Lincoln managed to successfully feed her the tapioca mixed with food coloring, and he then proceeded to pat Lily on the back until she made a big burp.

"Ooh, that was a big one. Good job!"

And with that, the two siblings continued their special day together. They played peek-a-boo, they played horsey, and they made things out of wooden blocks. They then made their way to the couch to watch Blarney the Dinosaur sing and dance and just stand around. Just then, Lori entered, texting on her phone as usual.

"Lincoln, are you actually enjoying this dreck?"

"Hey, this show is for Lily. And if she likes it, then I like it. Isn't that right, Lily?"

Lily clapped her hands and giggled at the green dinosaur's antics, and Lincoln took that as a yes.

"Well, you might not like it for long. Lily's going to grow up eventually, and there'll be nothing you can do about it."

Lori walked back upstairs. Lincoln brushed off her comments as teenage cynicism. In his mind, Lily will always be his baby sister. His thoughts of the matter soon disappeared when a familiar foul stench reached his nostrils.

"OCK! LILY!"

"Poo-poo!"

"Time for a changing!"

Lincoln carried his baby sister to her room. He put her down, took out the toxic-smelling diaper, and threw it into the nearby genie.

"There," Lincoln said as he wiped Lily's butt, "all clean!"

Lily giggled as the wipe tickled her rump. Lincoln took notice and began to play along.

"Who's got a bubble butt? Who's got a little baby bubble butt? You do! YOU do!"

He pinched her buttcheeks to her amusement, and he then turned Lily around to get a good loom at her belly.

"Who wants a raspberry? Would you like a raspberry?"

Without giving Lily a chance to respond, Lincoln pressed his lips against her stomach and blew a big blow on it. She squealed around in a fit of ticklish delight, indicating that her answer would have been yes had she been given the time to answer. After a few more blows, the baby soon began to tire of the tickles, and she yawned a big yawn.

Seeing her tire, Lily put a fresh diaper on Lily and gently place her into her crib. He climbed in to to accompany her. This was the part of the day he liked most: for them to cuddle with each other for an noontime nap. Before both drifted off into Dreamland, Lincoln whispered something to his baby sister.

"Lily? Do you know what I like best about you? Nothing ever seems to bother you. You just walk into the chaos of this house, and you go through it with a smile. You know, I can't wait for you to say 'I love you,' because then I can say...I love you, too."

And with that, they fell asleep. It was another successful Lincoln-Lily Sunday, just like the last Sunday and the Sunday before.

Next Sunday, though, things would be a little different.
