Like @jacesterlingsmommy said breast milk bags are sterile and made of special material, and you can also pump directly into them if you're pumping to store. I asked my doctor the same question recently haha!

@showersoverflowers that's sweet I'll try to do that!

Definitely! check out amazon and don't forget to throw some on the registry. sometimes they give you discounts on things not purchased by your shower date

@showersoverflowers okay thank you so much happy I found someone who tried to use them!

@squirt22 thank you I'll check on there!

Breastmilk bags are sterile and some attach to pump. Milk bags are more made to be put in the freezer for liquid storage

check out Amazon. I found some on there pretty cheap

I have dealt with both and the ziplock bags leak so bad and are just a general pain to pour out

@mimiz oh I didn't know that

I think the seal and bag material. But could be wrong?! @cillagrace

I guess they latch to the pump I was thinking the same lol
