Hi Choccake,
Me too has problems in breastfeeding, till today also not enough milk, I need to give formula to supplement. Me every time pump only 20ml ;(. Yes my baby 2 days older than your girl, is also drinking 90ml now. And she needs to be fed every 2 hoursly interval even at night somemore is formula. Very tiring.
I tried to latch but hor ... she only prefer one side and the other side refused to latch. She sucks till I feel very pain and I have phobia letting her to latch. My supply till today also only 20ml for each side.
Choccake - we just continue to pump even though is only 20ml, just don't give up. Whatever we have, just give to the little princess. Just don't stress. Me now looking after her myself, sometime dont have time to pump but I still try. We jiayou ya.
