It must be ridiculously exasperating to find a woman who says ' It's not my fault, my partner battered her when she was 3 1/2 months old', loses care of her child because of that and then goes and gets pregnant again by the SAME man. There is something fundamentally more wrong than simple drink and drug addiction, there is clearly a deep seated sense of no self worth whatsoever within these women. As you say it's almost impossible to turn your life around in 9 months, so the only answer can be, if there is an answer at all in these sad cases, to engage the women during care proceedings for their first child, make a stringent contract with them involving rehabilitation ad relationships with other abusive partners and get them to agree to contraception for three years whilst they engage on their quest to turn their lives around. If they agree and do what is required then obviously that's good, if they don't then it should be made clear that they will have any subsequent children taken into care also. Nothing is ideal in these scenarios, it's a horrible mess, but that at least gives women who are genuinely determined a second chance.
