I am also a working mum and should bring the pump along with me everyday. I pump 4 times a day and each time has 6-7 oz except in the morning and before sleep pump. The morning and before sleep could pump 3-4 oz as I used to feed my baby before pump. I am also worrying I could not keep the milk quantity. But until now, my girl has not take even 1 drop of the formula. Keep up to do the following, and the milk will come eventually,
- relax, drink water, fish soup, milk, sleep, feed the baby direct
