Alcohol and breastfeeding guidelines for nursing mums.

After abstaining from drinking alcohol during pregnancy you may questioning when and how much you can drink whilst nursing your baby. Whilst it’s generally recommend to avoid alcohol in pregnancy, the advice for breastfeeding mums is a little more relaxed. Whether you simply want to enjoy a glass of wine with dinner or celebrate an occasion with a few drinks, here’s what you need to know. 

1. Firstly you need to be aware of how many units of alcohol can be found in an alcoholic drink. This NHS guide should help. For example a standard 175ml glass of red/white/rosé wine or champagne contains 2.1 units whilst a single 25ml shot of spirits has 1 unit, a 330ml bottle of 5% lager is worth 1.7 units. 

2. Drinking heavily whilst breastfeeding can affect your child’s development and inhibits your milk let down. However various sources suggest that occasionally drinking one or two units of alcohol whilst breastfeeding won’t harm your infant, with a few organisations warning to wait until your baby is older than 3 months to allow their body (liver) enough time to mature and be able to process the alcoholic content in the breastmilk. 

3. What you need to know is that alcohol passes freely into your blood stream and your breast milk. Equally, it passes freely out of your breast milk and blood stream. 

4. To limit the affect of alcohol on your breastfeeding baby, you should abstain from nursing whilst the alcohol passes out of your breastmilk

5. If you do wish to have an alcoholic drink, it’s recommended that you have a drink straight after one of your baby’s feeds and then abstain from nursing whilst the alcohol passes out of your breastmilk.

6. Limit your alcoholic intake to 1 or 2 units then leave 2-3 hours between having a drink and nursing your baby to allow time for the alcohol to leave your system & breast milk.

7. Alcohol leaves your system at around one unit every two hours.

8. Peak levels of alcohol appear in the milk after 30 –90 minutes.

9. As long as you follow these basic guidelines, there’s no need to ‘pump & dump’ (express your milk and throw it away).

10. If you are planning on drinking more than a couple of units, it’s advised that you plan in advance and build up a supply of expressed breastmilk for another trusted carer to bottle feed your baby with.

General advice is that you should abstain from drinking whilst nursing until after your baby is 3 months old. Alcohol can change the taste of your milk and some babies may not like this. It may cause them to fuss at the breast, drink less than usual or it may upset their tummy. It’s also suggested that babies don’t tend to sleep so well after breastmilk that contains alcohol.

Please remember that being intoxicated reduces your ability to care adequately for your baby. You should therefore ensure your baby is properly cared for by someone who is not drinking. To avoid the danger of suffocation to your baby, you should never co-sleep with your baby after drinking. If you are drinking heavily or continuously, you may need to use a breast pump to alleviate engorged breasts whilst you skip nursing your baby - as the milk will contain alcohol, you will need to throw this away.

If in doubt, please seek medical advice from your gp or doctor.
