Going back to work- pumping. Pitcher method ?

Ka

I’m going back to work next week, and I worry about my grandmother having to thaw and warm up my babies bottles every 2-3 hours.

Has anyone tried the pitcher method?

I think it’s where you put a days worth of pumping into a pitcher and pour it into bottles for the next day? (I may be wrong)

I feel like that would be much easier on her.
