I wasn’t aware once a mother was nursing that it became necessary to stimulate milk flow. How about smoking pot? Wouldn’t that help stimulate milk flow too?
I never had trouble producing milk, but you do hear about women who have to stop breastfeeding bc of inadequate supply such that the baby is not satisfied or not gaining weight. They start supplementing with formula and then for SURE the supply will dwindle.
I am not aware of any research on marijuana use for this.
But it is not unheard of for nursing mothers to be recommended that glass of wine.
