Summary: It's not that Katsuki didn't want kids. He figured he'd have them one day, probably. That he and Izuku would adopt or maybe figure something else out.
This is NOT how it was supposed to go.

CHAPTER 22
“You’re extremely demanding for someone who can’t even hold her own head up yet,” Katsuki tells Toshiko while changing her diaper again.
She responds by staring at him with profound seriousness before peeing all over the onesie he just wrestled down over her arms. Because he hadn’t gotten the new diaper on her yet, and okay, that one’s on him.
“Don’t look at me,” Katsuki mutters at her as she kicks her chubby legs around. “I’m new here, too, y’know. Barely know what the fuck I’m doing.” He sighs as he reaches for another clean outfit. “Rookie mistake, though, I get it.”
By early afternoon, he’s pacing the living room in slow circles, Toshiko tucked against his chest, when he finally caves.
“Yeah, okay,” he speaks aloud. “We’ve gotta get out of the house. Time to meet Aunt Kyouka, huh?”
Toshiko gurgles in response.
“Exactly, kid. I’m saying.”
Kyouka doesn’t look at all surprised to see him when she opens the door. “Denki mentioned it was Midoriya’s first day back,” she says, gesturing Katsuki inside. “You look like you’ve been awake for three years, by the way.”
“I feel like I’ve been awake for fifteen,” Katsuki returns dryly. “You know it only took me sixty seconds to walk across the street? We live way too fuckin’ close to each other.”
“That’s your fault.” Kyouka leans in close to get a clear look at Toshiko’s face and her eyes widen in quiet delight. “I was going to pull a you and show up on your doorstep if you didn’t invite me over soon. Gosh, she’s cute.”
Katsuki shifts Toshiko in his arms, turning her so Kyouka can reach out to tickle her belly. “I know, right?” he says, practically preening, and Kyouka just shoots him a faintly amused look before redirecting her attention back to the baby.
“Look at all that hair,” she says in awe. “Kanami still doesn’t even have that much.”
“Ma said I was like that, too.” He pauses for a moment. “You can hold her, you know.”
Kyouka jumps on the invitation, instantly scooping Toshiko away from Katsuki and cradling her in the crook of her elbow.
“Hello, beautiful,” she coos down at her, gently bouncing her arms as she turns to head into the living room. Katsuki trails behind, catching sight of Kanami laying on a play mat on the floor not far from the couch. “You’re so big already, huh? Do you want to meet your new best friend?”
