Beer And Breastfeeding: What's Safe?

Nursing mothers are often faced with conflicting advice about whether it is safe to consume alcohol while breastfeeding. While it is generally advised to avoid alcohol altogether, the occasional drink is unlikely to harm the baby, especially if the mother waits for at least two hours after drinking before nursing. This allows time for the alcohol to leave the breast milk, as the alcohol level in the milk closely parallels the alcohol level in the mother's blood. However, regular alcohol consumption can negatively affect the mother's milk supply and the baby's development, growth, and sleep. Therefore, moderation and planning are key for nursing mothers who choose to consume alcohol.

Occasional drinking is okay, but regular drinking can decrease milk supply

It is okay for nursing mothers to have an occasional drink, but drinking alcohol regularly can negatively affect your milk supply and your let-down reflex, a hormonal reaction that allows your body to eject milk for breastfeeding.

Occasional Drinking is Okay

It is generally considered safe for nursing mothers to have an occasional drink. Alcohol passes into breast milk, and it is recommended to wait at least two hours after drinking before breastfeeding to avoid exposing your baby to any alcohol. This allows time for the alcohol to leave your breast milk. The more you drink, the longer it takes for the alcohol to clear your system.

Regular Drinking Can Decrease Milk Supply

Regularly consuming alcohol can have a negative effect on your breast milk supply. Obstetrician Kathryn Newton states, "People who drink regularly tend to have a lower milk supply than those who don't drink at all." Drinking alcohol can also delay the let-down reflex, resulting in the baby getting less milk.

Planning and Moderation are Key

If you choose to drink alcohol while nursing, planning and moderation are essential. Understand your body and drink responsibly, timing your drinks and knowing how much you can safely consume. It is recommended to breastfeed right before having an alcoholic drink and then waiting about two hours per drink before nursing again. If you need to feed your baby before the alcohol has cleared your system, you can use previously expressed milk.

Seek Professional Advice

If you feel that your alcohol consumption is interfering with your ability to breastfeed, it is important to seek advice from a healthcare professional. They can help evaluate your habits and support you in making changes for your health and well-being, as well as your baby's.

Alcohol passes into breast milk and can affect the baby

The amount of alcohol in human milk after the consumption of one standard drink is about 95% of the amount of alcohol in the mother or lactating parent's bloodstream. The absolute amount of alcohol transferred into the milk is generally low and is a function of the maternal level. Excessive alcohol levels may lead to drowsiness, deep sleep, weakness, and decreased linear growth in the infant. Maternal blood alcohol levels must reach 300 mg/dL before significant side effects are reported in the infant.

Nursing babies who are regularly exposed to alcohol through breast milk may experience developmental and neurological problems and trouble gaining weight. Research suggests that nursing after drinking can affect a baby's sleep. In one study, babies fed alcohol-laced milk slept more frequently but for shorter periods each time. In another study, babies spent less time in active REM sleep in the three-and-a-half hours after consuming alcohol-laced milk but made up for these REM deficits later.

It is important to note that drinking alcohol while breastfeeding can also impact the mother or lactating parent. Alcohol can interfere with the milk ejection reflex, leading to a reduction in milk production. Regularly consuming alcohol can have a negative effect on the let-down reflex, resulting in the baby receiving less milk. Additionally, people who drink regularly tend to have a lower milk supply than those who do not drink at all.

The amount of alcohol in breast milk depends on the amount in the mother's bloodstream

The amount of alcohol in breast milk is directly related to the amount in the mother's bloodstream. The alcohol level in breast milk is essentially the same as the alcohol level in a mother's blood. The highest alcohol levels in milk occur 30 to 60 minutes after a woman consumes an alcoholic beverage, but food delays the time of peak milk alcohol levels.

According to the Centers for Disease Control and Prevention (CDC), the occasional drink is okay for breastfeeding parents. However, it is important to limit the frequency and amount of alcohol consumed while following strict safety precautions to protect the baby. Generally, if a mother drinks one alcoholic beverage, it will leave her breast milk in about two hours.

The key is to wait until the alcohol has left the mother's system before breastfeeding again. This will ensure that the baby is not exposed to alcohol through the breast milk. The more alcohol a mother consumes, the longer it takes for the alcohol to leave her system and the longer she should wait before breastfeeding. For example, after drinking one alcoholic beverage, it is recommended to wait for at least two hours before nursing the baby. If a mother has two drinks, she should wait for four to five hours.

Exposing a baby to alcohol through breast milk can impact everything from development to sleep. Even though the amount of alcohol in breast milk is smaller than expected, it is not without risks. Studies have shown that nursing babies who are regularly exposed to alcohol through breast milk may experience developmental and neurological problems and trouble gaining weight. Therefore, it is important for breastfeeding mothers to drink responsibly and plan in advance to ensure the safety of their babies.

Drinking can affect the baby's sleep

Drinking alcohol can have a significant impact on a baby's sleep patterns and growth/development. Research has shown that babies exposed to alcohol in their mother's milk experience sleep disturbances, including shorter sleep periods, more frequent wakefulness, and less total active and REM sleep.

One study found that infants exposed to alcohol in their mother's milk spent significantly less time in both active and total sleep. Their REM sleep was also disrupted, and they experienced increased startling/arousal. As a result, they may appear sleepier but do not sleep as long. This disruption in sleep can continue for up to 24 hours after exposure to alcohol in the mother's milk as the infant makes up for the earlier disruption.

The amount of alcohol in human milk closely parallels the amount in the mother's bloodstream, peaking approximately 30 to 60 minutes after drinking. Nursing after one or two drinks can decrease the infant's milk intake by 20 to 23% and cause infant agitation and poor sleep patterns. The more alcohol consumed, the longer it takes for the alcohol to clear the mother's system and the longer the disruption to the infant's sleep patterns.

It is important to note that newborns are more affected by alcohol in breast milk due to their immature livers, and babies of all ages metabolize alcohol slower than adults. Therefore, the effects of alcohol on their sleep patterns and development can be more pronounced and last longer.

While moderate alcohol consumption (one standard drink per day for women) is generally considered safe for breastfeeding mothers, it is essential to consider the potential impact on the baby's sleep and development. Drinking in moderation and waiting at least two hours after drinking before breastfeeding can help minimize the amount of alcohol passed to the baby through breast milk.

Pumping and dumping is not necessary

According to the Centers for Disease Control and Prevention (CDC), alcohol leaves breast milk at the same rate that it leaves your bloodstream. Therefore, the amount of time it takes for alcohol to leave your breast milk depends on how much alcohol you consumed and how much time has passed since you drank. It takes about two hours for the average adult to metabolize one drink.

The CDC recommends that breastfeeding moms wait at least two hours after consuming a standard drink before nursing or pumping milk for their baby. This gives your body enough time to metabolize the alcohol and eliminate it from your milk. However, the amount of alcohol that passes into your milk is typically quite low, even after a drink or two. Research suggests that the amount of alcohol in breast milk is just 5-6% of the adjusted maternal dosage. So, if you’re only having a drink or two, it’s unlikely to have any negative impact on your baby.

According to the CDC, moderate alcohol consumption by a breastfeeding mother (up to one standard drink per day) is not known to be harmful to the infant, especially if the mother waits at least two hours after a single drink before nursing.

Pumping and dumping may actually be counterproductive. Pumping won't make the alcohol leave your milk supply or your body any faster than simply waiting. The idea that pumping and dumping rids your breast milk of alcohol is a myth. The only way to lower the alcohol content in your breast milk is time.
