Lactation cookies are a type of cookie that helps encourage milk production postpartum. They are made with special ingredients called galactagogues, which are intended to help increase a mothers milk supply. These cookies can be homemade or bought from bakeries, grocery stores, or online retailers. Lactation cookies are most effective for new mothers who have had their milk come in. Some of the possible ingredients in lactation cookies include oats, flaxseed, brewers yeast, nuts or nut butters, sugar, and flours. Breastfeeding mothers have higher calorie needs than normal, so eating a few lactation cookies may help meet those needs. While there is limited scientific evidence to prove that lactation cookies can help with milk supply issues, there is enough anecdotal evidence to suggest that they can be a helpful tool for those struggling with low milk production. Lactation cookies can be a helpful addition to a breastfeeding mothers diet, but it is important to speak with a lactation consultant or other healthcare professional to ensure they are the right fit for you.
