Try pumping for 15-20 min and try to relax. I believe your supply comes after 3 days. I've drank mothers milk tea which has fenugreek in it, drink lots of water and eat oatmeal.
Babies don't need that much milk in the first couple days of life. Keep trying it will come! Don't get discouraged, drink LOTS of water and eat healthy and more calorie intake as well.
***this? Hoe can I improve my breast milk? Help plz
