#god i had to really consciously stop myself from 'yall need a toothbrush for christmas'

[willowser]

aww aww katsuki coming home to find you and your kiddos in the kitchen, a disarray of gingerbread and icing and candies spread out across the dining room table.

you'd managed to dye your daughters frosting pink, and she's jumping up and down on her tippy-toes when she sees him, grinning so hard the tendons in her neck are straining. she'd wanted to build and decorate her own gingerbread house this year, but so far she's spent the last twenty minutes being very particular about only the first wall.

"daddy!" she leans her head all the way back when he puts his hand on her face, giggling beneath his palm with her little squished nose. "look at mine, look at mine!"

your wobbly son jumps up in his own chair, using the table as leverage to balance himself as he lets out a squeal of gibberish that vaugely sounds like an echo of what his sister is saying. at the excited pitch in his voice, her head whips around, free from katsuki's grip as her brows furrow.

"he's not even decorating anything," she protests—and she's not wrong; whatever your little boy is doing hardly classifies as 'decorating', and is more like 'eating all the frosting he can before getting caught'. there is a mess of sugar dried all around his mouth.

still, your son squeals in his chair, jumping up and down with even more energy when you place a hand on his butt, in case he slips. the promise of you only encourages him, and katsuki reaches across the table to snatch him up when he tries to get his little knee up on the surface.

your daughter's frown grows; sharing attention remains a soft spot for her. instead of saying anything, she only makes an annoyed little sound and presses her cheek into her dad's hip.

"stuff's gonna give you cavities," katsuki murmurs, though he picks up a few red and green candies and shares them with your already sugary boy—who hums happily. "need a toothbrush for christmas."

"no," your daughter pulls back and tugs on his belt loops, sneering up at him playfully when he pinches her nose. "you have cavities!"

katsuki makes a point to bare his teeth at her, and then presses his forehead to his son and does the same until they're both giggling. "ain't me, bighead,"

"you're a bighead!"

"yeah, 'n i am big, so what's your excuse?" a wicked little grin splits his face when she starts swinging on him, and he deposits your son into your lap before scooping her up off her feet, her girlish scream vibrant and happy in the space around you.

katsuki waits until she calms down a bit, holding her to his chest like a baby, before coming around the table to get a good look at her little pink masterpiece. he presses his mouth into her hair, like he does with you, and her little ruby eyes sparkle when he murmurs, "looks good, kid,"—just to her and only to her.
