First of all, a mom who can’t stop smoking should breastfeed. Breastfeeding provides many immunities that help your baby fight illness and can even help counteract some of the effects of cigarette smoke on your baby: for example, breastfeeding has been shown to decrease the negative effects of cigarette smoke on a baby’s lungs. It’s definitely better if breastfeeding moms not smoke, but if you can’t stop or cut down, then it is better to smoke and breastfeed than to smoke and formula feed.
The more cigarettes that you smoke, the greater the health risks for you and your baby. If you can’t stop smoking, or don’t want to stop smoking, it’s safer for your baby if you cut down on the number of cigarettes that you smoke.

- Babies and children who are exposed to cigarette smoke have a much higher incidence of pneumonia, asthma, ear infections, bronchitis, sinus infections, eye irritation, and croup.
- Colic occurs more often in babies whose mothers or fathers smoke or if a breastfeeding mother smokes. Researchers believe that not only does the nicotine transferred into mother’s milk upset baby but the passive smoke in the home acts as an irritant. Babies of smoking parents fuss more, and mothers who smoke may be less able to cope with a colicky baby (due to lower levels of prolactin).
- Heavy smoking by breastfeeding moms occasionally causes symptoms in the breastfeeding baby such as nausea, vomiting, abdominal cramps and diarrhea.
- Babies of smoking mothers and fathers have a seven times greater chance of dying from sudden infant death syndrome (SIDS).
- Children of smoking parents have two to three times more visits to the doctor, usually from respiratory infections or allergy-related illnesses.
- Children who are exposed to passive smoke in the home have lower blood levels of HDL, the good cholesterol that helps protect against coronary artery disease.
- Children of smoking parents are more likely to become smokers themselves.
- A recent study found that growing up in a home in which two parents smoked could double the child’s risk of lung cancer later in life.
Smoking has been linked to:
- Earlier weaning. One study showed that the heaviest smokers tend to wean the earliest.
- Lower milk production
- Interference with milk let-down
- Lower levels of prolactin. The hormone prolactin must be present for milk synthesis to occur.
- One study (Laurberg 2004) indicated that smoking mothers who live in areas of mild to moderate iodine deficiency have less iodine in their breastmilk (needed for baby’s thyroid function) compared to nonsmoking mothers. The study authors suggested that breastfeeding mothers who smoke consider taking an iodine supplement.
Although smoking has been linked to milk production and let-down problems, this may be related to poor lactation management rather than physiological causes. Dr. Lisa Amir, in a review published in 2001, concluded that “Although there is consistent evidence that women who smoke breastfeed their infants for a shorter duration than non-smokers, the evidence for a physiological mechanism is not strong.”
- The ideal: Stop smoking altogether.
- Cut down. The less you smoke, the smaller the chance that difficulties will arise. The risks increase if you smoke more than 20 cigarettes per day.
- Don’t smoke immediately before or during breastfeeding. It will inhibit let-down and is dangerous to your baby.
- Smoke immediately after breastfeeding to cut down on the amount of nicotine in your milk during nursing. Wait as long as possible between smoking and nursing. It takes 95 minutes for half of the nicotine to be eliminated from your body.
- Avoid smoking in the same room with your baby. Even better, smoke outside, away from your baby and other children. Don’t allow anyone else to smoke near your baby.

In this study, researchers examined school results of 570 nine-year-old children who were born in a Dutch hospital between 1975 and 1978 and whose mothers smoked during the pregnancy. Per the researchers, “Our results indicate that negative effects of maternal smoking on children’s cognitive performance were limited to those who had not been breast fed.” The children who had not been breastfed had decreased cognitive performance compared to the children who were breastfed. The researchers suggested that breastmilk promoted brain development and helped to counteract the adverse effects of cigarette smoking during pregnancy.
