I tried before and same as you. I can only pump 1-2 oz. but when I breastfeed my bb at one side and pump milk with another side at the same time, I can pump 4-5oz within 15 mins(only 1 side). By my experience, better to give your baby 啜多d instead of pump in the first month until you have more milk and be more stable. otherwise, baby cannot have enough milk when breastfeed. you only 17 days, may be too 心急to pump milk out lu.
