Fatherhood!KnS+Kagami
It was chaos, and Kagami was at the center of it all, being the only one who seemed to have a shred of common sense and be able to function without his wife around.
"Why is she still crying? Oh sweetie please don't cry! Taiga-cchi, help me!" Kise was in a very panicked state as he ran around helplessly with his baby daughter in his arms.
"Stop screaming, Ryouta and just let her sleep!" Kagami shouted back, taking the child and placing her in a nearby crib.
"B-but she needs her daddy!" Kise wailed, picking the baby up again.
"Why won't they eat, Taiga?" Aomine demanded furiously. He was holding both his and Murasakibara's sons while Mura went to fetch more diapers.
"Because. They. Can't. Eat. Meat. Yet." Kagami said through gritted teeth, replacing the large steaks with baby food. Aomine was a surprisingly good cook, and he looked down at the mush, insulted.
"No baby of mine will eat this garbage." He said, walking into the kitchen muttering what sounded like demonic chants under his breath, but Kagami had no time to worry about that because Kuroko suddenly appeared beside him.
"I can't find my daughter. She disappeared." Kuroko had a strangely calm, proud look on his face.
"Now isn't the time, Tetsuya!" Kagami said, grabbing the nearest moving object that had a tuft of baby blue hair. For some reason, Kuroko's daughter was strangely attached to Kagami and was always within grabbing distance. "Here she is..."
Kagami sat beside his own son, who was sleeping peacefully somehow...then, the door opened. Midorima and Akashi came in, the only two childless out of the original gang. Midorima was still getting his PhD, and had firmly decided on no children until both he and his wife had a steady career and a stable income. Akashi had a similar situation, only he was wrapped up in the complex customs of the upper class, and was still convincing his parents that his girlfriend was worthy of joining the household.
They took one look at the mayhem, and Midorima, who had taken care of his baby sister as a kid, kicked all the fathers with the exception of Kagami out. Midorima held up Kagami's son with a look of horrid fascination. "Amazing, Taiga. Your son is asleep..."
Akashi chuckled, surveying the mess.
"You certainly have your hands full, Taiga."
Kagami flopped into the nearest chair. "More so with the fathers than with the children, actually."
They tried to ignore the shrieking of Kise, the angry yells of Aomine and the thumping of Murasakibara's fist against the door. It became difficult once Kuroko started launching basketballs at the door.
