Hi, just to share ...
Me back to work last week, exclusively pump, now pump 4x per day (morning around 6.30 am, 2x at office, 11am and 5pm and at nite 10pm).
Total per day is around 800ml plus.
My girl drink 5 x 130ml, so enough to cover the daily needs and have extra to freeze.
Previously pump 5-6x per day before went back to work, the supply down a bit (before is around 900ml).
I'm using PISA, usually will take 10 mins to pump (max the power) and follow by squeeze for another 10-15 mins. Found that the PISA can not dry up the milk, when squeeze can still get another 50ml plus.
