You shouldn't obstruct their nose, but otherwise no.

Cool. Do babies ever randomly die or can you pretty much expect that if you have a baby and don't forget about it for a year you'll have a kid?

They die very rarely and generally only if the court has misfortune.

Neat. Do they have close calls?

Honestly it's kind of hard to tell?

Is it?

Like sometimes they seem unwell and then recover but maybe they weren't unwell and were just briefly in pain or something?

Has anyone ever tried having a slow person watch over them?

Doesn't work very well once they start to speed up but it works until then, yeah. 

No known way to partially slow an adult?

When slowing a person down they slow down gradually and you can stop this partway through though that's rarely advisable.

If you can only do it in that direction it'd make it hard to match the baby for very long.

He looks at the baby.

It is very small and pink and only vaguely human-shaped.

Does it match a fetal development stage? (How old is this baby?)

It does not, quite, match a fetal development stage. This baby was extracted about three weeks of sidereal time ago.

Cam makes an anatomical diagram as best he can without being able to move it around. He supervises the baby for a while to see if it will wake up before Econ Faery does.

It does not.

"How's the baby."

"Doesn't look like a human baby or fetus, quite. I might make a mindless one to have a closer look at later."

"That's such a convenient ability. Did you want to stay and watch it more?"

"Nah, I have no way to know when it'll wake up."

"All right. Did you get any guesses about what you were curious about?"

"Baby faeries are almost certainly not just running on magic to survive delivery at three months. I did watch the baby long enough to see it was breathing, so it's got lungs. I want to find out more about how things behave at various intermediate speeds but that's more of a separate question."

"Yeah, that's interesting but it's mildly annoying to learn so I've never done it. There's not a lot of reason to be anything other than slow or fast."

"Well, I mostly want to avoid being slow, since somebody might spot me, but probably if I were only two hundred times faster than a human I could avoid that with just a little effort and conduct research while I was there. I expect to get around to that in the next million years."
