2. I heard the Pigeon is the WORST, don't buy it. I recommend Medela Mini-electric. No need to make yr hand tired.
3.Yes, hv to steam as bottles. Recommend you buy one more set the funnel. Steam at home first then bring to work. Then you do not need to sterilize in office.
5. You can place the bottle (covered) in the fridge directly.
6. OK for freshly pumped milk to be kept at room temperature for 1-2 hours.
