A family court judge in Rochester, New York, has ordered a drug-addicted woman to have no more children until she proves she can look after the seven she already has.

It's the second time Judge Marilyn O'Connor (search) has made such a ruling.

The 31-year-old mother had already lost custody of her children, ranging in age from eight months to 12 years. Three of them tested positive for cocaine at birth.

In a similar ruling last March, Judge O'Connor ordered a drug-addicted, homeless mother of four to refrain from bearing children until she won back care of her children. The decision, the first of its kind in New York, is being appealed.
