SIGCHLD is the signal the parent gets from the kernel when the child terminates. Other than that, there are no special "children signals."

A forked child is an exact copy of the parent, until the child starts developing own ideas. Signal handlers should be the same in the child - if they are set up before forking, that is.

I guess at this point I need to see a bit more of the code involved to make an educated guess.
