I have also started using Medela bags to supplement boiling. I just neb daily, but use my sinus bottle 2x daily. I boil all a couple times a week, but use the Medela bags after washing equipment after each use with dawn in water that’s just been boiled in between long boils.
I just ran into a issue while on a trip-it was very hard to find wattage on hotel microwaves and I didn’t find it on one. I used same time as at home on that one.
