A commenter on this post has made the point that many women who suffer domestic violence are terrified of seeking help for fear of having their children taken into care, and gave a link to a YouTube video on the subject by (I believe) Dr. Lynne Wrennall (incorrectly spelt 'Rennall' in the video) of Liverpool John Moores University.
