I'd add something to Prudie's advice. She mentioned possibly getting social services involved. As a public defender, I dealt with over a hundred such cases. In my area, at least, the introduction of social services into a family situation was easy but their removal was often very difficult. For example, they may be brought in to deal with inadequate supervision, but once they are in, they might identify budgetary problems, or cleanliness problems, etc. Some of the caseworkers have gotten a bit twisted by the power they wield (by virtue of the credibility they typically enjoy in court) and become overly controlling and intrusive. I've seen family relationships pushed over the edge by the oversight and humiliation brought on by agency involvement.
This may vary by area, but I would suggest you try nearly any other option before trying social services, or at least that you discreetly seek out objective opinions from those who know how your local agency operates. Their resources can be quite helpful, but there is often a high price to pay.
