Okay.

What about with other Children?

That's never happened before given the antipathy most children have for each other. Theoretically, it would be possible to have a child, which would have power, drawn from both parents (making each a little weaker in the process). But of course that varies wildly, given that a lot of the Children aren't even anatomically compatible. Some matches would work, some wouldn't.
