Uppermoon Babies!?

Abt you: Upper moon 1 with Kokushibo you are usually cold ruthless emotionless to hashiras sometimes you smiled creepily at them but whne it comes to upper moons you treat them like children. So Muzan was holding a potion until he saw Kokushibo in a distance he thought ut was Yorichi about to kill his upper moons he threw the potion at Kokushibo and he turned into a baby also bc Nakime was about to tp Kokushibo to the others whicj made the rest into babies as well.(Except Nakime cuz she is biwa playing)(no Gyokko and Hantengu)
