My baby girl is 4 weeks old now. I am still only producing about 2-3 oz total when I pump. I am feeding her on demand and am pumping typically 2-3 times a day. I feel like she is not getting enough during feedings as usually she sits on there for about an hour or so. She drifts off, but if i completely remove her she wakes up crying and starts feeding again. At this point in her age, how much milk should i be producing? Does anyone have any tips to help raise supply? I struggled with supply with my first and I really wanted to be able to do it more so this time around. Any advice is appreciated!
