Not sure if you’ve had too much to drink? This free breastfeeding and alcohol calculator can help you determine your breast milk alcohol level and make an informed decision about when to nurse again.
Many women wonder if they can have alcohol while breastfeeding – and at what point it is safe to nurse again after drinking.
If you have decided to drink alcohol while breastfeeding, you might wonder how long alcohol stays in your system. We’ve developed this calculator to give you a general idea of what your breast milk alcohol level is based on what you’ve been drinking and how much time has elapsed.
Please keep in mind that this tool is not a medical calculator and is just a tool. You should use your best judgment when deciding to resume breastfeeding after you drink alcohol – not just because this calculator told you that it was okay.
Breastfeeding and Alcohol Calculator
Your breast milk alcohol level is the same as your blood alcohol level. This level will depend on various factors, such as your weight, height, if you’ve eaten anything, etc.
In the calculator, it will ask you to select how many drinks you have had. For the purposes of this calculator, the following are what we are referring to when we say one drink:
- 12 ounces of 5% Beer
- 1.5 ounces of 40% vodka
- 5 ounces of 13% wine
Obviously, this doesn’t cover every type of alcohol you might be drinking, but it should be a good starting point.
Make sure you are truthful with your weight, how many drinks you’ve had, and how much time has elapsed since you last drank. None of this information is stored, so there is no way of us knowing what information you put in the calculator.
Again, this should only be used as an estimate. Listen to your body, be safe, and use good judgment. If you have been drinking a lot, make sure you have a responsible caretaker to care for your child.
Breast Milk Alcohol Calculator
Please note that the part at the bottom that gives an estimated amount of time until your breast milk alcohol level is at a zero doesn’t change when you put the hours elapsed – this is based simply on the information you provided about the number of drinks, weight, and gender.
This calculator helps you to determine your blood alcohol level based on your weight, the number of drinks consumed, and how long it has been.
The amount of alcohol in your blood directly correlates to the amount of alcohol in your breast milk! So once this calculator is down to zero, you should, ideally, be able to nurse your baby.
Is it Safe to Drink Alcohol While Breastfeeding?
There are a lot of varying opinions on this topic, however, the general consensus from most professionals is that if you are safe to drive, you are safe to nurse.
In our article, Alcohol and Breastfeeding, we share a lot of information on breastfeeding and alcohol consumption. It’s important to note that the decision to drink alcohol while breastfeeding is a very personal one, and it’s important to be aware of all the pros and cons – and, of course, to drink responsibly.
Do I need to pump and dump?
The main reason women are told to pump and dump is that people used to think it would speed up the rate at which the alcohol was removed from your breast milk.
This is not true.
There is no need to pump and dump for this purpose. It doesn’t remove the milk from your body any faster, as it is based on your blood alcohol level.
The only reason to pump and dump is if you are uncomfortable and feel that your breast milk has too much alcohol in it. If you are drinking a lot – or if you are separated from your baby while drinking, I would definitely recommend pumping to keep up your milk supply.
