Yukinko are snow yokai that appear in the shape of children. They are sometimes said to be the children of Yuki-onna.
It doesn’t play much of a role in legends, appearing as just a newborn baby asleep in swaddling clothes. There is some questions as to whether the Yukinko exists at all, or is just a creation by the Yuki-onna as a way to lay her trap. But from some of the stories, there is evidence that the Yuki-onna cares deeply for the Yukinko, suggesting that it is a real child after all.
