Is it okay to use sandwich bags to store breast milk in a deep freezer???

I think it's best to use breast milk bags because they're sterile, that's what I've read anyways

of course!

@showersoverflowers, thank you love :)

from my experience they end up costing you more than storage bags because they are constantly cracking and pouring them into a bottle is like baptizing a cat. Plus you really do not want to heat the plastic even if its just in warm water.
