There were quite a lot of condoms in Xiaomi's space, after all, when collecting supplies back then, she took everything from the supermarket, thanks to the large space. She didn't even spare the shelves.
But she couldn't just take these out; besides whether her parents would be scared, even if they weren't, they wouldn't know what they were or how to use them.
That night, Xiaomi fell asleep worrying, and in her dream, she saw her father holding two more children, telling her they were her younger siblings, scaring her awake.
Fortunately, it was just a dream; it was terrifying, wasn't it?
But after that sleep, it was already midnight, and Xiaomi skillfully fed her parents milk formula secretly.
Milk formula mixed with water from the Spiritual Spring, it's dual nutrition.
It might be the instinct of the body, getting used to the nightly feeding; even if sometimes Xiaomi made a little noise, they wouldn't notice.
