I was told 24 hours. Though the whole if you are sober then its fine, might bring on problems. Since there could still be a bit left in your system, but you feel fine.I would say to limit it to about a drink or two.

Although alcohol passes through your milk, the amount your baby gets is much less than the amount you drink. Studies have shown that alcohol levels in breast milk peak about 30 to 90 minutes after one drink,

I dont remember exactly, but I think I saw something about to be on the safe side, not to nurse for 8 hrs after you had your last drink, you can still pump at this time just discard the milk and begin nursing again like 8 hrs after your last drink as long as you didnt get s*it faced drunk lol, If it was me I would do that to be on the safe side as well…

Alcohol does pass freely into breastmilk, though in small amounts and in short duration. Alcohol is considered compatible with breastfeeding by the American Academy of Pediatrics Committee on Drugs and Chemicals and Human Milk.

Alcohol will leave the body as it is metabolized. Because there is little storage space in the breast, most of the breastmilk is made from the blood as it is called for by the baby. Therefore the level of alcohol in the breastmilk is more closely related to the level of alcohol in the blood at the time the breastfeeding is occurring, rather than the level of alcohol the mother consumed overall.

Since milk production slows during the time between feedings, alcohol will not be stored in the breastmilk and passed to the baby at a later feeding if that feeding occurs when the blood alcohol level is down.

An occasional drink — one glass of wine, one beer or one mixed drink — would not necessitate interrupting breastfeeding. However, daily drinking would not be recommended because it can inhibit milk let down and cause slow weight gain in the infant. Studies have shown that babies of mothers who drank beer breastfed more frequently but consumed less breastmilk than babies whose mothers did not drink alcohol. (Mennella and Beauchamp 1993) There is no truth to the old wive’s tale that drinking wine or beer will increase milk supply and enhance milk let down.

It would also be inadvisable to drink to the point of intoxication. Mothers who become intoxicated should not breastfeed until they are completely sober. When the mother becomes sober, most of the alcohol has left the blood and it should be safe to resume breastfeeding. Drinking to the point of intoxication, or binge drinking, has not been adequately addressed in studies of breastfeeding mothers and babies so all of the risks are not clearly understood.

Dr. Cheston Berlin, who was a member of the American Academy of Pediatrics Committee for Drugs and Chemicals in human milk, recommends no more that one or two drinks per week for the breastfeeding mother. He also advises “delaying breastfeeding for about six to eight hours after a night out with a few drinks.” (1992)

According to Thomas Hale, “alcohol is not considered harmful to the infant if the amount and duration are limited.” The alcohol you drink will peak in your blood in about 30 to 90 minutes. It will peak in the shorter time if you are drinking on an empty stomach and it will take up to 90 minutes if you are drinking while also eating. Dr. Hale suggests waiting for two to three hours after drinking before resuming breastfeeding.

The myth is 24 hrs. It’s not accurate but i think the reason it persists is because people frown on nursing after only an hour.

Man or Woman, breast feeding or not…it takes your body roughly 1 hour to process 8oz of beer or 2-3oz of straight liquor.

So if you have 2 shots you’d need 2-2 1/2 hrs for your body to filter the alcohol out of your system.
If you have one beer, it’s two hours PER beer.

Honestly i usually would pump and store if i knew i’d be having a beer or a glass of wine, and wait till the next day to nurse. I know the liquor would be out of my blood stream well before then, but it always made me feel “weird” nursing so soon after having a beverage. I never got drunk or anything, but on occasion had a glass w/dinner or a beer at a picnic or ballgame. I rarely drink anyways.
