I would suggest Every Detail. just write at the top of the form that you are updating it for addition in family and mention the date of updation.
this way they will jsut replace the page in your file.
please also include a cover letter in wihch you mention document list. I am copying the letter which i sent (passport was sent later). but you can add passport now.
