Can You Drink Alcohol While Breastfeeding? What You Should Know

Introduction

This is one of the most common questions new parents ask: Can I have an alcoholic drink while breastfeeding?

With so much advice shared online and through friends and family, it can be difficult to know what's accurate. Current guidance from organizations like the Centers for Disease Control and Prevention (CDC) and the Academy of Breastfeeding Medicine (ABM) can help you make informed decisions.

While not drinking alcohol is the safest option during breastfeeding, you may still wonder how an occasional drink could affect your breast milk and feeding journey. Here's what current evidence says.

Can You Drink Alcohol While Breastfeeding?

According to the CDC, not drinking alcohol is the safest option while breastfeeding. However, consuming up to one standard alcoholic drink per day is generally not known to be harmful to your baby, particularly if you allow enough time before breastfeeding again.

If you choose to drink, understanding how alcohol is processed by your body can help you plan feedings and reduce your baby's exposure.

Does Alcohol Pass Into Your Breast Milk?

Yes. Alcohol passes from your bloodstream into your breast milk, and the concentration of alcohol in your milk closely reflects the concentration in your blood. As your body metabolizes alcohol, the amount in your breast milk gradually decreases.

Unlike some substances, alcohol does not remain trapped in your breast milk. It naturally leaves your milk as it leaves your bloodstream.

How Long Does Alcohol Stay in Your Breast Milk?

The amount of time alcohol remains in your breast milk depends on several factors, including:

• How many alcoholic drinks you consume

• Your body weight

• Whether you drank with food

• How quickly you consumed the alcohol

According to the CDC, alcohol from one standard drink can generally be detected in breast milk for about two to three hours. If you have more than one drink, it will take longer for the alcohol to leave your system.

When Can You Breastfeed After Drinking?

If you choose to drink alcohol, planning ahead may help reduce your baby's exposure.

You may consider breastfeeding or expressing milk before having an alcoholic beverage. If your baby needs to feed before the alcohol has had time to leave your system, previously expressed breast milk may be an option.

Because alcohol leaves your breast milk as it leaves your bloodstream, allowing enough time for your body to metabolize the alcohol is the most effective way to reduce alcohol levels in your milk.

Do You Need to "Pump and Dump"?

In most situations, no.

A common misconception is that pumping and discarding breast milk removes alcohol from your milk. In reality, pumping does not speed up the removal of alcohol from your breast milk. Alcohol leaves your milk only as it leaves your bloodstream.

However, pumping may still be helpful if you need to relieve breast fullness or maintain your milk supply while waiting to breastfeed again.

Can Alcohol Affect Breastfeeding in Other Ways?

Research suggests that alcohol may temporarily affect breastfeeding in several ways.

Higher or repeated alcohol consumption may interfere with your milk ejection reflex (let-down), and some studies have found that babies may temporarily consume less milk during feedings that occur soon after alcohol consumption.

If you're working to establish or maintain your milk supply, it's helpful to be aware of these potential effects when deciding whether and when to drink alcohol.

Conclusion

If you choose to drink while breastfeeding, understanding how alcohol is processed by your body can help you make informed decisions. Alcohol naturally leaves your breast milk as it leaves your bloodstream, so planning your feedings and allowing enough time before breastfeeding may help reduce your baby's exposure.
