Are you confused with all the information out there? Not sure if you should believe your Aunt Sally who is telling you “never did you any harm when you were little” or maybe your friend who is telling you even a drop of alcohol will leave your baby with developmental delays! the big question on a lot of breastfeeding mums minds is Can you drink alcohol while breastfeeding this Christmas? Let’s have a look and get into in…
Does alcohol pass through to breastmilk?
Yes, alcohol does pass into your breastmilk, but not in the extreme way people often imagine. You will see exactly how it works below.
So, can you drink alcohol while breastfeeding this Christmas?
The short answer is yes. Research shows occasional drinking is compatible with breastfeeding when done safely. The important thing is understanding how alcohol works in your body and how timing feeds can help your baby receive very low or no alcohol exposure.
The research is reassuring when it comes to moderate and occasional drinking. We already sacrifice so much as mums, especially when breastfeeding, and Christmas should not be another time where you feel guilt or restriction. It can absolutely be a time to enjoy those festive moments while still keeping your baby fed and safe. Let’s get into it.
Things That Affect the Alcohol Level in Your Breastmilk
Your baby’s age
Your baby’s age influences how their body processes alcohol.
- Newborns have immature livers and take longer to metabolise alcohol
- Babies under three months process alcohol at about half the speed of adults
- Older babies metabolise alcohol more efficiently
- The younger the baby, the more mindful you may want to be
This does not mean you cannot have a drink. It simply means timing and moderation become more helpful.
Your size
Your body size plays a role in how quickly you metabolise alcohol. A larger person will metabolise alcohol faster than a smaller person.
How much you drink
The effect of alcohol on your baby is directly linked to the amount you drink. The more you drink, the more enters your bloodstream and therefore your milk, and the longer it takes to clear.
Eating while drinking
Having your festive tipple while tucking into a mince pie or, even better, your Christmas dinner, decreases the absorption rate of alcohol into your bloodstream.
How Much Alcohol Passes Into Your Breastmilk?
Here is the fact that simplifies everything.
Breastmilk is made from your blood.
This means the alcohol level in your breastmilk matches the alcohol level in your blood.
- If your blood alcohol level rises, so does the alcohol in your milk
- When your blood level falls, your milk level also falls
There is no trapping of alcohol in the milk already sitting in your breasts. It leaves your milk naturally as it leaves your bloodstream.
So you will not be making your own eggnog in your boobs by avoiding pumping and dumping.
Time is the only thing that clears alcohol from your milk.
When does alcohol peak in breastmilk?
- Around 30 to 60 minutes after drinking
- Around 60 to 90 minutes if you had food with it
For most women, one standard drink takes about two hours to clear.
A reassuring comparison
Your blood alcohol level would need to reach 300 mg per 100 ml before significant side effects might be seen in your baby.
For reference, 80 mg per 100 ml fails a police breath test.
You would need to be extremely drunk to reach that level. And realistically, if you were that drunk, you should not be caring for a baby anyway.
Does Alcohol Affect Milk Supply?
Occasional festive drinks generally do not cause problems. Larger or more frequent drinking can:
- Temporarily slow milk letdown because alcohol affects oxytocin
- Lead to your baby taking less milk in the three to four hours after you drink
- Influence supply if drinking heavily or often
Most babies naturally make up for this later by feeding more. For occasional Christmas drinks, milk supply is not usually affected long term.
Is It Safe to Have Wine While Breastfeeding at Christmas?
Yes. An occasional drink is considered low risk. The amount of alcohol in your breastmilk after a single drink is typically a drop in the ocean if you are drinking responsibly.
If you want to be extra cautious, a simple approach is:
- Feed your baby
- Have your festive drink
- Wait about two hours per drink before breastfeeding again
This keeps the amount of alcohol in your milk very low or undetectable.
How Much Alcohol Can You Drink When Breastfeeding?
Be cautious if:
- You are binge drinking
- You feel intoxicated
- You are less able to respond to your baby
Heavy or frequent drinking can impact your baby’s development, growth, milk supply, and safe sleep practices.
If you are drinking more than usual over Christmas, it can be helpful to make a plan for safe baby care.
Never share a bed or sofa with your baby if you have had alcohol.
Planning a Christmas Event or Night Out
So, can you drink alcohol while breastfeeding this Christmas? Yes! You can absolutely enjoy festive celebrations while breastfeeding. These tips keep things smooth:
- Feed your baby before you leave or before your drink
- Express milk in advance if you want a bottle available
- If you skip a feed, pump or hand express for comfort
- Remember that your milk clears naturally as your body clears alcohol
A little planning goes a long way.
