it's not unusual for social services to suggest that the women be sterilized
Even this is out of order. It is not up to social services to police how many babies women have.
Sure, if a woman doesn't want more children, then she could discuss sterilisation with a doctor.
But if she does want more, then why not suggest long acting contraception e.g coul instead?
Also, why is it women that are getting this? Vasectomy is cheaper and less risky. Why aren't social services targeting the partners of these women to get the snip?
Would it be ok for social services to identify men who had fathered large numbers of children and push them to be vasectomised?
