The main ingredients in these cookies (oats, almond butter and banana) are great for breastfeeding moms. If you want to increase your breastmilk supply a little more, add in ground flax seed and/or brewer's yeast. Ground flax seed contains phytoestrogens which can positively influence breast milk production and can help balance hormones during the postpartum period. Brewer's yeast is a good source of B vitamins and iron which can support milk production (VeryWell Family).
