I assume that this is being done with an Automation when record ADDED
You can have the first Action in the Automation to be to delete any existing child records (just for that one Parent!!), and then the next step in the Automation can is to copy across the correct ones. ie start with a "clean slate" every time.
Note that you can add the Delete Action and then you can drag it up to be first.
