London is marking its first ever Smokefree Pregnancy Week.

The aim of this week is to help mums and dads to be quit smoking.

There were 106,696 live births in London in 2022.

With 3.9% of pregnant women in London smoking at time of delivery, this equates to 4,200 babies being born in London to a smoker.

The NHS explains that cigarettes can restrict the essential oxygen supply to your baby.

This can result in premature or still birth, low birth weight and increased risk of sudden infant death syndrome.

Pregnant smokers and their partners can get free one-to-one behavioural support, Nicotine Replacement Therapy or vaping kits as part of the event.
