Couple questions: 1 - is your baby gaining weight? 2- have you tried pumping like more frequently? 3 - how old is your baby? 4 - do your breasts feel full in between feedings? Do you end up leaking?

Saffron and Shatavari
Lots of water with a pinch of Celtic salt in every glass. It helps water absorb into your body better and will help milk supply. Drink like 3 more glasses than you think you should have to per day
You can get a supplement that helps produce more milk. I got one when I had my daughter, and it really helped . I forgot the name. Ask your docter . Good luck mama
