I can think of two things:
1) a timer object. You could start the timer when the child is created and after a set period of time end the timer and refresh. Of course the problem is determining the right period of time because people will work at different paces.
2) If you could submit the parent after the children are created you could then open the parent again when the child is submitted. The problem with that is that the user won’t get to flip back and forth between the two.
We have some good power users that read this forum. Perhaps one of them can think of something that I have not.
