A new campaign is encouraging pregnant women and new mothers to stop smoking. Smokefree Mum is run by Sheffield Teaching Hospital Trust and Sheffield City Council.
Currently in the city, 14.1% smoke at delivery stage, with more deprived areas in the city peaking at 19.5%.
Due to the health risks associated with smoking during pregnancy, and the increased treatment costs, the Government is aiming to reduce the number of mums smoking at birth to 11% nationally by 2015.
"Being pregnant can be one of the most rewarding times in a woman's life and there is no doubt new parents want the best start possible for their babies. I am sure everyone knows the health risks associated with smoking when pregnant - to mothers and of course their babies. But we know it can be really hard to quit smoking, especially if it is something you have done for a long time. Having someone to support you with this process really does help.
