Has anyone tried supplements from legendairymilk.com ? If so do they work? I’m a skeptic when it comes to these things. I am trying to increase my milk supply by eating healthy drinking plenty of fluids and taking my vitamins. Also I am constantly breastfeeding pumping and also supplementing only 2 oz of formula when needed since my little one eats a lot. What do you nursing moms do to increase your supply?
