Trust me, I read the whole thread from beginning to end. LOL Unfortunately a microwave is not option for me. I used to have a great apartment complex on my route, the ladies said I could use their full kitchen and pump there when I returned to work. Then management adjusted the routes while I was out on maternity leave, and now it's not on my route anymore. And - big fat sigh - it's too far for me to go there anyway - we are only allowed to travel 1/2 mile from the route.
On the plus side, my milk is still holding at 6 hours! It still tastes okay for now. I will be tasting it again at 12:30 am to see if it reaches the 12 hour mark. If so, I will be able to save my day's pumped milk and scald it if I have to. But I'm hoping it will hold for at least 24 hours, then I will only have to scald my freezer stash.
I also pumped again this evening and scalded that. Half of it is sitting in the fridge, and the other half I put in the freezer. I'll have to see how long it stays good and go from there.
