Alcohol affects everyone across the lifespan

Alcohol: Preconception, pregnancy, and breast/chestfeeding

I am thinking of becoming pregnant, should I avoid alcohol?1

If you are thinking about becoming pregnant or planning a pregnancy, you should be aware of the effects alcohol can have on your body. Being aware about the risks of alcohol can help you to make informed decisions when making choices about your health and your fertility.

If I am pregnant and drink alcohol, can it hurt my baby?1,2

Yes. There is no safe amount of alcohol to consume while pregnant. Using alcohol while pregnant can lead to complications, birth defects, and abnormalities such as:

Longer-term effects include learning difficulties, and health and social effects with lifelong impacts such as Fetal Alcohol Spectrum Disorder (FASD) (Health Canada).

Can I use alcohol if I breast/chestfeed?

You should avoid drinking alcohol while breast/chestfeeding your baby. Using alcohol while breast/chestfeeding can also have negative impacts on your child because alcohol passes through breast/human milk. Alcohol can affect infant sleep patterns, reduce growth rates, cause difficulties with breast/chestfeeding and lead to an early end to breast/chestfeeding or a decrease in milk production.3,4

When you drink alcohol, it passes quickly from your blood to your milk supply. This means that the amount of alcohol in your milk is the same as the amount in your blood. As your blood alcohol level begins to decrease, so will the alcohol level of your breast/human milk.

If you are following the appropriate harm reduction measures listed below, occasional alcohol consumption while breast/chestfeeding has not been shown to be harmful to babies.4,5
