An estimated 11,864 unborn babies are exposed to harm from tobacco each year in Wales. And worryingly, as many as 16% of women continue the habit throughout their pregnancy – the highest of all the UK nations. Now midwives across Wales are raising awareness of the dangers of smoking and providing access to support to help pregnant mums-to-be quit. Smoking while pregnant puts both mother and baby at risk of significant harm. In fact, it doubles the chances of the baby being stillborn or having a heart defect.
