My good friend is a nurse practitioner and works long hours. Her breast milk started to dry out but she changed her diet, began getting more rest, and drinking more water. Still, she's not as productive as she was. Do you recommend any herbs or tinctures that can be used to stimulate her breast milk? Is there anything in your health and wellness line? She came across a company (Milky Mama) that makes cookies designed to stimulate breast milk but she was unsure about the company. Thank you for your insight.
