Alcohol and breastfeeding

Can I drink alcohol if I am breastfeeding?

Whether it's parties, BBQs, family get-togethers or celebrations; alcohol is often served at most social gatherings. But if you’re breastfeeding, there’s no wine for you. Or is there?

If you want to, you can enjoy a glass of wine, a beer or whatever it is that you choose to drink.  The key is to plan ahead.

The concentration of alcohol in your blood is the concentration of alcohol in your milk.

Alcohol gets into your breastmilk from your blood, moving freely from the blood to the breastmilk (and back out again).

To know when your breastmilk is free of alcohol, we suggest you download the Feed Safe app.

Alcohol will be in your breastmilk 30–60 minutes after you start drinking.

A number of factors affect how much alcohol gets into your breastmilk, including:

  • the strength and amount of alcohol in your drink
  • what and how much you’ve eaten
  • how much you weigh
  • how quickly you are drinking.

As a general rule, it takes 2 hours for an average woman to get rid of the alcohol from 1 standard alcoholic drink and therefore 4 hours for 2 drinks, 6 hours for 3 drinks and so on. The time is taken from the start of drinking. The Feed Safe app can help you work out these times more accurately.

Only time will reduce the amount of alcohol in the milk in your breasts.

Once you stop drinking, and the amount of alcohol in your blood drops, the amount in the milk in your breasts will too.

‘Pumping and dumping’ (expressing breastmilk and throwing it away) will not reduce the amount of alcohol in your breastmilk. You also do not need to do this once the alcohol has passed through your system – alcohol is not ‘stored’ in the milk in your breasts, just as it doesn’t remain in your blood. Once the alcohol is out of your blood, it will be out of your breastmilk.

When breastmilk with alcohol is expressed, that expressed breastmilk will contain and continue to contain alcohol.

Alcohol and breastfeeding appPlan ahead

The safest option when breastfeeding is to avoid drinking alcohol altogether.

However, planning ahead can allow you to express some milk for your baby ahead of time. Your baby can have this milk if you miss a feed while drinking, or while you are waiting for the amount of alcohol in your milk to drop.

If you are breastfeeding and plan to consume alcohol, it is best to plan ahead. However, if, on a single occasion, you have a little more alcohol than you had planned to or if your baby needs to feed sooner than you had anticipated it is OK to breastfeed your baby. 

Carers who are under the influence of alcohol may make less safe decisions about where their baby sleeps, so it is important to plan ahead and ensure safe sleeping arrangements have been made and never to sleep with your baby if you have been consuming alcohol.
