Harry Potter x BabySister! Reader *Platonic*
Ron and Hermione stared at Harry, completely stunned by the baby in his arms. She babbled happily as she wiggled her little arms up at her brother.
"Um, Harry. Care to explain?" Hermione asked sternly. Harry sighed before getting a better hold of his sibling before sitting down, his sister perched on his lap.
"Alright, alright. This is my little sister, (Y/n). I don't like leaving her with our Aunt and Uncle so I brought her with me this year," he said, watching the (Y/h/c) haired baby crawl to Hermione, who couldn't help but pick her up and play with her.
"I don't think they'll allow her in mate, I mean, she can't even walk yet," Ron said to Harry who was sitting across from him.
"I'll sneak her in, it's fine,"
"Who's gonna look after her while you're learning?" (Y/n) reached her chubby little arms out to the red head and Ron sighed but took her from Hermione.
"Hagrid,"
"Hagrid?!" Ron and Hermione said in unison as the twins appeared. They frowned at their younger brother.
"Ron..." Fred started.
"Did you kidnap that child?" George finished.
"What?! No! She's Harry's sister! I'm not a child thief!" He exclaimed, as yet again the little Potter reached her arms to the twins.
"Wow, she wants to meet everyone," Hermione said as George picked her up and gently booped her on her little nose making her giggle. Fred joined in, in making her laugh.
"Can you say Freddie? Say Freddie,"
"No say Georgie,"
The child looked between two boys and frowned slightly.
"F-feddie," she tried and Fred's face lit up.
"Hah! She likes me more!"
"Shut up," George tuts, but hugs the bubba anyway.
"We need to make her our little mischief apprentice, teach her the way of pranks," Fred suggested.
"Yeeeeessss," George agreed.
"Absolutely not," Harry said.

3rd POV (focusing on (Y/n))
(Y/n)'s little innocent (E/c) eyes watched the odd boys who looked the same, curiously as they began to argue with her brother a bit. Bored, she started to wriggle so the one holding her would put her down and without any of them noticing, she crawled out the cart and down the narrow hallway of the carriage she was in. The first few doors she passed were closed but coming upon the final cart she found the door open and as the curious little thing she was, she crawled in and looked at the occupants. Three boys and a girl. The girl whose hair reached just above her shoulders spotted the child first and sneered.
"Ugh, I hate babies," saying this, she caught the attention of the three boys. They also looked down to see the little (Y/h/c) baby sat there watching them.
"Why?" the platinum blonde haired boy asked, not seeming to understand her choice in words. Sure, Draco had never had a younger sibling or had much time to bond with any other babies but he found them rather cute despite their lack of knowledge of the world.
"They smell, and drool and leave a mess," Pansy said before, gently but forcefully trying to nudge the little girl out the cart with her foot. (Y/n) looked at the foot that was gently nudging her and soon she became tired of it, frowning at the foot then the girl. She lifted her hand and slapped the foot, giving a little baby scream as she did so. Draco laughed at her actions before standing and picking her up before sitting down and setting her on his knee. He bounced his leg a bit making the baby giggle as Pansy folded her arms and sulked.
"Where did you come from then, huh?" Draco asked, gently booping the baby's nose with his index finger.
"(Y/n)! Goodness, has anyone seen a baby?!" A frantic voice could be heard along with running feet. Harry looked in the cart and saw his sister, sighing in relief. "There you are, thank yo--," when he saw Draco holding his sister he frowned a bit as Draco the same to him.
"She's your sibling, very irresponsible of you to lose sight of her, Potter. Shame, she is your sister though. We were getting on pretty well," Draco said as (Y/n)'s chubby little hand reached up and patted Draco's pale cheek.
"Yeah well it won't happen again. Can I have her back now please?" Harry frowned, holding his arms out. Draco stood lifting up the baby Potter and handing her to her older brother. The (Y/h/c) baby snuggled into her brothers shoulder as he turned to leave.
"Oh and Potter...."
Harry turned to the blonde with an expressionless face.
"Can we discuss babysitting dates?"
This story is an absolute delight, seamlessly blending humor, heart, and the wonder of a child in the magical world of Hogwarts. The addition of Harry’s baby sister, (Y/n), is a unique twist that brings warmth and freshness to the familiar dynamic. The sibling bond shines through, and the interactions with the other characters, especially the Weasley twins, are charming and hilarious. The mischievous nature of the twins and their instant affection for (Y/n) is heartwarming and true to their personalities. The way (Y/n)’s innocence contrasts with the chaos of Hogwarts life adds a layer of endearing unpredictability.
This story would be perfect for adaptation into visual mediums. As a comic or webtoon, the adorable moments and expressions of baby (Y/n), paired with the magical setting, could be beautifully illustrated. A motion comic would further bring the laughter and charm to life with animated gestures and voiceovers for the playful banter.
Would you be open to discussing this idea further? I’d love to connect via email or Discord (my handle is noir_love) to explore the possibility. As a commission artist specializing in transforming stories into visual art, I’d be thrilled to collaborate and help bring this delightful tale to life!
