I think (untested) you can do something like

trap 'kill <pid of child>' TERM

at then beginning of parent.sh. This way, when the parent recives TERM it 
in turn sends a TERM to the child. If you want the parent to terminate, 
add the exit command as well:

trap 'kill <pid of child>; exit 1' TERM

(don't know how the parent can wait for termination of child, but it 
should be possible I think)

"man trap" gives you the details.
