This is a yes and no question. It is best not to have alcohol in the first month but once breastfeeding is established, you can have up to 1-2 standard drinks per day, as long as you time your feeds to wait for it to be out of your system. For all the facts about drinking and breastfeeding, see below for a detailed article and to download the brochure.
A number of factors affect how much alcohol gets into your breastmilk, including:
As a general rule, it takes 2 hours for an average woman to get rid of the alcohol from 1 standard alcoholic drink and therefore 4 hours for 2 drinks, 6 hours for 3 drinks and so on. The time is taken from the start of drinking. The Feed Safe app can help you work out these times more accurately.
