Prevent children to be stopped by SIGTERM

I wrote this script (I removed some useless stuff):

#!/bin/bash

readonly ARGS="$@"

catch() 
 echo "Sigterm caught"
 # Perform some cleanup instructions
 # that suppose the child process is still alive
 trap - SIGTERM # remove the trap
 kill -s SIGINT -- -$$ # Sends SIGINT to child/sub processes
 exit 0


main() 

 trap "catch $5 $4" SIGTERM

 ./child_process_program # With all arguments needed



main $ARGS

I start this script with the script as follows: timeout "10s" ./my_script <arguments>.

The problem is that sigterm reaches also the child_process_program and so the instructions that suppose the child process is still alive cannot succeed.

I already see a very similar question with answer and tried (unsuccessfully) to change main as follows:

main() 

 trap "catch $5 $4" SIGTERM
 set -m
 ./child_process_program & # With all arguments needed

But I did not succeed. Is there a solution to my problem?
