quick question..
Does breastmilk storage bags have to lay flat? And why??
If you don't store them flat they get all bulky at the bottom and super thin on top, making them a very awkward shape to try to store. Also it's a lot harder to dethaw because instead of it being less than a half inch all the way across, it's an inch thick in some places and it takes FOREVER to dethaw it
Yeah, laying them flat just helps them thaw out quicker and saves space. I used to freeze them while laying flat and then just stand them up in a shoe box or ice cube bin for storage.
