Can a Breastfeeding Woman Drink Red Wine?

Yes, a breastfeeding woman can drink red wine in moderation (up to 1 standard drink per day), but she must wait at least 2 hours after consuming the drink before nursing or expressing milk to minimize infant alcohol exposure. 1, 2

Timing and Safety Guidelines

Alcohol Transfer Dynamics

• Breast milk alcohol concentrations closely parallel blood alcohol concentrations, with peak levels occurring 30 to 60 minutes after consumption. 1, 2
• The 2-hour waiting period allows for substantial alcohol clearance from breast milk before the infant feeds. 1, 2
• Careful planning of breastfeeding schedules—by storing milk before drinking or waiting for complete alcohol elimination—can ensure infants are not exposed to alcohol. 3

Moderate Consumption Definition

• Moderate alcohol consumption is defined as up to 1 standard drink per day (approximately 5 oz of wine, 12 oz of beer, or 1.5 oz of distilled spirits). 1
• This recommendation applies specifically to moderate consumption (≤1 drink per day), not higher amounts. 2
• Moderate intake does not appear to affect breastfeeding duration when appropriately timed. 1, 2

Important Caveats and Risks

Potential Infant Effects

• While the American Academy of Pediatrics states that moderate consumption with proper timing is "not known to be harmful," research has identified some concerning effects. 1, 2
• One study found that infants regularly exposed to alcohol through breast milk had significantly lower motor development scores at one year of age, with a dose-response relationship. 4
• Maternal alcohol consumption may slightly reduce milk production, contrary to cultural beliefs that alcohol stimulates lactation. 5
• Infant alcohol exposure through breast milk may adversely affect sleep patterns and gross motor development. 5

Clinical Pitfall

• Avoid the common misconception that alcohol enhances milk production—this is folklore not supported by evidence. 6, 5
• The belief that only "strong" alcohol or large quantities are harmful is incorrect; any alcohol transfers to breast milk. 6

Practical Algorithm for Decision-Making

If choosing to drink:

1. Limit to 1 standard drink (5 oz wine)
2. Nurse or pump immediately before drinking
3. Wait minimum 2 hours before next nursing session
4. Consider pumping and discarding milk during the 2-hour window if engorgement occurs
5. Have stored milk available for infant feeding during the waiting period

Absolute avoidance recommended for:

• Women who cannot restrict drinking to moderate levels 1
• Those with a family history of alcoholism 1
• Mothers of premature or very young infants (who metabolize substances more slowly) 7
• Women taking medications that interact with alcohol 1

Safest Recommendation

While moderate consumption with proper timing may be acceptable according to AAP guidelines, complete abstinence remains the safest approach to eliminate any potential risk to infant development. 8, 4 The evidence shows measurable effects on infant motor development even with regular moderate exposure, suggesting that the precautionary principle favors avoiding alcohol entirely during breastfeeding when possible. 4
