Storage of Breastmilk

Letting out excess air from the storage bag is to allow enough space for the milk expansion. But since you are not freezing it, then it really does not matter. Doing this also makes for better space allocation.

Usually those storage bags kept in fridge are fed to the baby within the day also. Just be careful don't mix the bags with raw stuff in the fridge

I think better to take the air out first, just to be double sure of not having any bacteria in the bag before storing

Usually I will let out the air. Just worried that the bateria in the air would contaminate the milk.

I will let the air come out for easy storage. So that I can stack them

No issues as long as u have space in the fridge

For easy storage
