it looks small to me you might need to get bigger flange. you can increase breastmilk by nursing and after nurse pump to stimulate more milk production. or you can eat milk booster food.
Yes flange looks a little too small. Your nipples are brushing along the flange and it will cause bruising in the long run.
Flange is too small. I pumped 15 mins each side. To increase breast milk, i will pump After nursing to empty the breast
pump every 2 hours if you cant get baby to latch. i used to pump for 20 mins.
