The capital is urging parents who have broken family planning policies to register their extra births before Nov 1.

According to Xi Kaili, a spokesperson for the Beijing Municipal Commission of Population and Family Planning, families who register their extra births now will face only minimal fines while those who attempt to hide the births of "illegal" newborns will have to raise those children without the benefit of citizenship.

China's family planning policies encourage most urban residents to limit their family size to one child.
