Hey Brittney! Congratulations on your new little one and on your decision to nurse. I BF both of my boys for many years and can't speak highly enough of the benefits. As a health and wellness coach I agree with what Kris suggested. Lots of plant based whole foods. I just posted a wonderful smoothie recipe that would work great for you. I would leave out the matcha and add in brewers yeast which helps milk supply. I'm happy to answer any other questions you have.
Love and health,
