Breastfeeding and drinking alcohol
There’s some evidence that regularly drinking more than two units of alcohol a day while breastfeeding may affect your baby’s development. But an occasional drink is unlikely to harm your breastfed baby.
It’s recommended that breastfeeding mothers have no more than one or two units of alcohol once or twice a week.
One unit of alcohol is approximately a single (25ml) measure of spirits, half a pint of beer, or 125ml (small) glass of wine, although this depends on the strength of the drink.
To check units in other drinks, see Alcohol Concern’s alcohol unit calculator.
Risks of binge drinking
Binge drinking, where you have more than five units of alcohol in one session, may make you less aware of your baby’s needs. If you do binge drink, it’s essential your baby is cared for by a sober adult.
Never share a bed or sofa with your baby if you have drunk any alcohol. Doing this has a strong association with sudden infant death syndrome (SIDS).
Alcohol and your breast milk supply
There’s no evidence that alcohol, including stout, helps you produce more milk.
Rest, being well in yourself, and letting your baby breastfeed whenever they want will all help increase your milk supply.
