How much alcohol is safe to drink when pregnant?
In Australia, drinking alcohol is very common. It is often linked to social and cultural activities.
Australia has guidelines to help lower the health risks from drinking alcohol. These include advice for people who are pregnant, planning a pregnancy, and breastfeeding. They can help you to make an informed decision about how much alcohol you drink.
The guidelines advise that pregnant women should not drink alcohol. This is to stop your unborn baby being harmed by alcohol.
When you drink alcohol, so does your unborn baby. Alcohol passes from your blood through the placenta and to your unborn baby. The placenta cannot stop the alcohol from reaching your baby.
When you are pregnant, there is:
- no safe time to drink
- no safe amount to drink
- no safe type of alcohol to drink
Alcohol can harm your baby at any point during your pregnancy.
What effects does alcohol have on my unborn baby?
Drinking alcohol while pregnant can increase your chance of:
FASD is the term used to describe the effects on the baby from drinking alcohol during pregnancy.
The effects of FASD are life-long. People with FASD often need support with:
- motor skills
- physical health
- emotional regulations
- social skills
What should I do if I drank alcohol before knowing I was pregnant?
You might have drunk alcohol before you knew you were pregnant. The risk from low level drinking before you knew you were pregnant is likely to be low.
If you are concerned, speak to your doctor or midwife. You can also call NOFASD Australia on 1800 860 613 for confidential information or support.
Once you know you are pregnant, it’s safest to stop drinking.
What if I’m planning to become pregnant?
If you’re planning to become pregnant, not drinking is the safest choice for both parents. There is still a lot we don’t know about how alcohol affects sperm.
What if I’m breastfeeding?
If you’re breastfeeding your baby, not drinking is the safest choice.
When you drink, the alcohol moves from your blood into your breastmilk. It takes about 30 to 60 minutes for this to happen.
A few factors affect how much alcohol gets into your breastmilk, including:
- the alcohol you are drinking (strength and amount)
- what you’ve eaten
- how much you weigh
- how quickly you are drinking
It takes about 2 hours for an average woman to be free of alcohol from one standard drink.
If you choose to have an occasional drink, you can plan to protect your baby. You may wish to breastfeed your baby before having an alcoholic drink.
The Australian Breastfeeding Association has a Feed Safe app to help you understand when your breastmilk is free of alcohol.
How can I avoid alcohol during my pregnancy?
It can be hard to avoid alcohol in social situations, particularly when others might not know you’re pregnant. A good alternative is to have a non-alcoholic drink.
If you don’t want people to know that you are pregnant, you might also find it helpful to say:
- No thanks, I’m on a health kick and have given up alcohol.
- No thanks, I have to drive.
- No thanks, I have a big day tomorrow.
If you’re happy to tell people that you are pregnant you can just say:
- No thanks, not while I’m pregnant.
Where can I get support to give up alcohol?
If you’re finding it hard to give up alcohol while you’re pregnant or breastfeeding, talk to your doctor, midwife or obstetrician for advice.
