Breastfeeding 101 Help

Hi, FTM here currently at 34 weeks and hoping to breast feed when our baby arrives. I'll also be going back to work so bottle feeding, pumping, and freezing is all necessary. Here are a couple of my questions, but additional advice is welcome.

How much milk do you put in each storage bag?

How do you go about thawing and warming breast milk for your baby?

Do you have a routine for getting it ready and transporting it for daycare or events?

Are there any products that have been super helpful to you for any of this?

I appreciate any advice you are able to provide.
