Creating a child record from a button on the parent form and automatically return back to the parent form after the child has been saved.

Yes! That was the trick!!!

Now, instead of enabling the user to create multiple Grand Child Records (Root Cause) through the button, is there a way to disable the button from adding multiple records after an initial record has been created and possibly indicating on the button such as a color change to tell the user a record has been created? Essentially I just want the user to edit the original record through the button instead of creating new records.

Your help is greatly appreciated!!
