I think we can do this simply by keeping our eye on the Process Status table, where particular process id is generated for the processes.
By that we can check the parent or child process has been started or not and accordingly we can react on that.
Each process has a process id, its status (R/Z/O/S), and name of the process.
I think this idea will work, but ofcourse we have to monitor the ps table closely.
Thanks
