Not drinking alcohol is the safest option for breastfeeding mothers. Generally, moderate alcohol consumption by a breastfeeding mother (up to 1 standard drink per day) is not known to be harmful to the infant, especially if the mother waits at least 2 hours after a single drink before nursing. However, exposure to alcohol above moderate levels through breast milk could be damaging to an infant’s development, growth, and sleep patterns. Alcohol consumption above moderate levels may also impair a mother’s judgment and ability to safely care for her child.
Drinking alcoholic beverages is not an indication to stop breastfeeding; however, consuming more than one drink per day is not recommended.
Can alcohol be found in breast milk?
Yes. Alcohol levels are usually highest in breast milk 30-60 minutes after an alcoholic beverage is consumed, and can be generally detected in breast milk for about 2-3 hours per drink after it is consumed. However, the length of time alcohol can be detected in breast milk will increase the more alcohol a mother consumes. For example, alcohol from 1 drink can be detected in breast milk for about 2-3 hours, alcohol from 2 drinks can be detected for about 4-5 hours, and alcohol from 3 drinks can be detected for about 6-8 hours, and so on. However, blood alcohol levels and the length of time alcohol can be detected in breast milk after drinking will depend on a number of factors, including the amount of alcohol consumed, how fast the alcohol is consumed, whether it is consumed with food, how much a mother weighs, and how fast alcohol is broken down in a mother’s body.
What effect does alcohol have on a breastfeeding infant?
Moderate alcohol consumption by a breastfeeding mother (up to 1 standard drink per day) is not known to be harmful to the infant, especially if the mother waits at least 2 hours before nursing. However, higher levels of alcohol consumption can interfere with the milk ejection reflex (letdown) while maternal alcohol levels are high. Over time, excessive alcohol consumption could lead to shortened breastfeeding duration due to decreased milk production. Excessive alcohol consumption while breastfeeding could also affect the infant’s sleep patterns and early development.
