Beer And Breastfeeding: What's Safe?

Drinking alcohol while breastfeeding is a topic that has been the subject of much research, especially given that approximately half of all lactating women in Western countries consume alcohol while nursing. While there is no evidence that drinking a small amount of alcohol while breastfeeding is harmful to the baby, opinions vary over the amount of alcohol that is safe for a breastfeeding mother to drink. The general consensus is that drinking alcohol in moderation will not affect the baby, but drinking regularly or heavily may impact the mother's milk supply and the baby's growth and development.

Drinking alcohol while nursing is generally considered safe if done in moderation

Firstly, it is worth noting that there is limited research on the effects of alcohol consumption while breastfeeding. While it is widely accepted that alcohol should be avoided during pregnancy, the impact of alcohol on breast milk and nursing babies has not been as extensively studied.

That being said, here is what we know so far. Alcohol does pass into breast milk, and its concentration in the milk closely parallels the mother's blood alcohol level. This means that if a mother's blood alcohol content is 0.10%, her breast milk will have the same alcohol content. The highest alcohol levels in milk typically occur 30 to 60 minutes after consuming an alcoholic beverage, although food can delay this peak.

To minimise the amount of alcohol ingested by the baby, it is recommended to wait at least two hours after drinking before nursing or pumping. This is because it takes about two hours for the average adult to metabolise one drink, and during this time, the alcohol will also be metabolised out of the breast milk. The more drinks consumed, the longer it takes for the alcohol to clear the system, so it is advised to wait about two hours per drink before nursing.

It is also important to note that drinking alcohol can negatively impact milk production and the milk ejection reflex. Alcohol interferes with the hormones oxytocin and prolactin, which are involved in milk production and the let-down reflex. As a result, babies may consume less milk after their mothers have consumed alcohol.

Additionally, drinking alcohol while nursing may affect the baby's sleep patterns, even after consuming a small to moderate amount. Some studies have also suggested that repeated exposure to alcohol in breast milk could have long-term negative effects on the baby's development, including potential harm to cognitive and motor skills.

Therefore, while the occasional drink is generally considered safe, it is important to drink in moderation, wait at least two hours per drink before nursing, and prioritise the baby's safety at all times. If in doubt, it is always best to consult with a healthcare professional for personalised advice.

Alcohol can remain in breast milk for as long as it's in the drinker's bloodstream

It is important to note that there are varying recommendations for breastfeeding women when it comes to alcohol consumption. While some healthcare providers urge abstinence, others state that occasional drinking carries little risk. The general consensus is that moderate alcohol consumption (up to one standard drink per day) is considered acceptable. However, it is crucial to provide lactating mothers with accurate information on the effects of alcohol as data in this area are limited.

Alcohol consumed by a mother passes freely into her breast milk, and the amount of alcohol in the breast milk closely parallels the mother's blood alcohol level. The highest alcohol levels in milk occur 30 to 60 minutes after consuming an alcoholic beverage, and the length of time alcohol can be detected in breast milk depends on the amount consumed. Alcohol from one drink can typically be detected for about 2 to 3 hours, but this extends to about 4 to 5 hours for two drinks and 6 to 8 hours for three drinks.

As alcohol leaves the bloodstream, it also leaves the breast milk. Therefore, alcohol can remain in breast milk for as long as it is in the drinker's bloodstream. Pumping and dumping will not remove alcohol from the breast milk or speed up its elimination. Time is the only way for alcohol to leave the breast milk as the body metabolizes it.

To minimize exposure, it is recommended to wait at least 2 hours after drinking before breastfeeding. This allows for the alcohol to be cleared from the breast milk. It is also important to consider the baby's age, as newborns have immature livers and are more affected by even small amounts of alcohol.

Drinking alcohol can negatively impact milk production and the milk ejection reflex

Research has shown that nursing infants consumed less milk in the three-to-four-hour period after mothers consumed a small to moderate amount of alcohol. One study showed a 23% decrease in milk volume with just one drink. Another study found that drinking as little as 0.3 g of alcohol per kg (which is less than the amount considered acceptable by the American Academy of Pediatrics) reduced milk production by about 10%.

Alcohol also affects the baby's sleep patterns. Studies have shown that infants breastfed by women who had consumed alcohol prior to nursing experienced sleep disturbances, including shorter sleep periods, more frequent wakefulness, and less total active and REM sleep in the three-hour period after consuming alcohol.

Furthermore, alcohol can decrease linear growth in the infant and lead to slow weight gain. Maternal blood alcohol levels must attain 300 mg/dL before significant side effects are reported in the infant, including drowsiness, deep sleep, and weakness.

Overall, drinking alcohol can negatively impact milk production and the milk ejection reflex, leading to reduced milk intake and potential negative effects on the baby's sleep and growth.

The more alcohol consumed, the longer it takes for it to clear the body

It is important to note that the effects of alcohol consumption while breastfeeding are not yet fully understood. While there is no evidence of harm to babies from drinking no more than one alcoholic beverage per day, it is generally recommended that breastfeeding mothers avoid alcohol consumption or limit their intake. Alcohol can be detected in breast milk for about 2-3 hours after one drink, 4-5 hours after two drinks, and 6-8 hours after three drinks. The more alcohol consumed, the longer it takes for it to clear the body.

The rate at which alcohol is metabolised depends on various factors, including genetics, amount consumed, age, weight, and food intake. On average, the body metabolises alcohol at a rate of 15-25 milligrams per hour, but this can vary depending on individual factors and the amount consumed. The liver is primarily responsible for breaking down alcohol, but a small amount is also eliminated through sweat, breath, and urine (about 2%-5%).

To ensure the safety of the baby, it is recommended to wait at least 2 hours after drinking one standard drink before breastfeeding. If more than one drink is consumed, it is advisable to use previously expressed milk or formula to feed the baby. Additionally, drinking alcohol on an empty stomach increases its effects on the body and can interfere with the hormones involved in milk production. Eating food while consuming alcohol can slow the rate at which alcohol enters the bloodstream, but it does not affect the speed of alcohol metabolism.

It is important to note that the effects of alcohol on the baby are directly related to the amount consumed. Alcohol can cause drowsiness, deep sleep, weakness, abnormal weight gain, and impaired motor and cognitive development in infants. It can also disrupt the mother's milk ejection reflex, leading to decreased milk intake by the baby. Therefore, it is crucial to be mindful of alcohol consumption while breastfeeding and to follow the recommended guidelines to ensure the safety and well-being of the baby.

Pumping and dumping breast milk does not remove alcohol from it

Pumping and dumping may still be helpful for other reasons, such as avoiding engorgement and leaky breasts if the alcohol hasn't had time to leave your system before a feeding session. It can also help to maintain your milk supply while you wait for the alcohol to metabolize out of your system.

Additionally, it is important to note that drinking alcohol while breastfeeding can have negative effects on both you and your baby. Alcohol can inhibit let-down and decrease milk production. It can also change the taste of your milk, making it less desirable to your baby. Regular and heavy alcohol consumption can decrease your milk supply and may have consequences for your baby's development. Therefore, it is recommended to drink in moderation and time your alcohol consumption to minimize the amount of alcohol passing through your breast milk.
