Breastfeeding mothers have concerns about alcohol, smoking, and vaping effects on their babies.
Moderate alcohol consumption is safe as alcohol clears from breast milk as it does from the bloodstream.
Excessive drinking can negatively affect milk production and infant development.
"Pump and dump" is not necessary as alcohol level in milk matches that in the mother's bloodstream.
Breastfeeding while smoking is safer than formula feeding, but quitting smoking is ideal to avoid harm from smoke and nicotine exposure.
