Re: how to bring the milk home
BM is good for 7 days if it is in the refigerator. It is good for 10 hours at room temperature, so even if you can't refrigerate it all day it will still be fine if you can get it in the fridge when you get home.
I always kept mine in the frige at work, then brought it home and put it in the frige at home. I pumped into the (plastic) bottles I fed the kids with the next day and never froze mine.
Here's a quick reference on storage guidelines.
“We are not put on earth for ourselves, but are placed here for each other. If you are there always for others, then in time of need, someone will be there for you.”
