Interesting feature on Women's Hour today. Suggests women from lower socio-economic backgrounds don't usually even attempt b/f and interviews a number of women about why they didn't want to and what is being done to provide better information to encourage women to make an informed choice.
Think this will take you to the Listen Again page - go to the bottom & click Women's Hour on the Top 5 box (assuming your pc has speakers and you are not at work!)
