Scientific evidence shows that around 30% of sudden infant deaths could be avoided if mothers didn’t smoke when they were pregnant.
Taken together with the risks of smoking around a baby at home, this means that smoking could be linked to 60% of sudden infant deaths.
- Both you and your partner should try not to smoke during pregnancy and after the birth
- Smoking both during pregnancy and after your baby is born greatly increases the chance of SIDS, and your baby can be affected by either you or your partner smoking
- You should also keep your baby out of smoky areas – Don’t let people smoke near your baby and keep your home, car, and other places your baby spends time, smoke free
- If you or your partner smoke, you should not share a bed with your baby as this greatly increases the chance of SIDS even if you do not smoke in the bedroom
If you smoke 1-9 cigarettes a day during pregnancy you are more than four times as likely to have a baby die as a sudden infant death than a woman who didn’t smoke at all during pregnancy.
Even if you did smoke when you were pregnant, you should still try not to expose your baby to smoke after birth as this can help reduce the risk of sudden infant death. Quitting smoking is not easy and will require a lot of discipline, but it is an effort worth making.

What is Nicotine Replacement Therapy, and is it safe in pregnancy?
Nicotine Replacement Therapy (NRT) involves the use of gum, patches or tablets to deliver a small amount of nicotine into your bloodstream. They are said to help you to deal with cravings by giving your body nicotine without some of the harmful by-products of smoking (e.g. carbon monoxide and tar).
Most pregnant women can use NRT safely, though it’s important to talk it through with your doctors first.
No one in my home smokes, and we rarely go anywhere smoky but I still worry if my child ever goes into a smoky environment. Can this increase the risk of SIDS?
The risk of SIDS from very occasional exposure to a smoky environment is likely to be very low, but there isn’t enough scientific evidence for us to know the precise risk. Try to keep your baby smoke-free at all times to keep them safe.
Is it safe to breastfeed if I smoke?
Breastfeeding has many benefits and regardless of whether you are a smoker or not it is the best way to feed your baby.
