If you continue to smoke when you are breastfeeding, wait to have a cigarette until after you have completed a feeding. You might be advised to wait at least three to four hours before breastfeeding again–even if it means that you have to pump and dump (where you express and discard some breastmilk).
In respect to this, can I have one smoke while breastfeeding?
Breastfeeding and cigarette smoke
Nicotine passes rapidly into your breast milk and affects how much milk you have. Nicotine in breast milk and passive smoking can give your baby chest infections, vomiting, diarrhoea and irritability. Avoid smoking for half an hour before you breastfeed.
Additionally, what happens if you breastfeed while smoking?
Smoking can cause low milk supply, colic, and milk let-down issues. If you do continue to smoke, you should still breastfeed. Your milk can protect your baby from breathing problems, sudden infant death (SIDS), and poor weight gain. Wait as much time as possible between smoking and breastfeeding.
