I am a mother of 6 week old child. My baby is fed formula and breast milk both since day one as people said I don’t have enough milk. I tried pumping and finding out. In the day time sometimes I get 100ml from both breast and by night it gets reduced to 30ml. Sometimes in day time also I get 30-40ml. I don’t have leaky breast, neither my breast feel tight. Does it mean I have low milk supply
