No adapter needed with my Spectra

These bags are great for storing my expressed breast milk while I'm at work. They fit on my pump flange perfectly without needing an adapter. The only downside is that some of them leak just a little bit. So I freeze them in a standing position instead of flat.

I love these storage bags. They freeze fas and thaw fast just as it stated. My newborn doesn't get a chance to fuss due to a long wait to thaw. I tried other brands but Lansinoh is the best.

Lets talk about storing the gold dust that is in fact breast milk!

As the return to work date is slowly creeping closer Im starting to build a stash so Betsy can access my milk whilst Im working. I used Lansinoh breastmilk storage bags with Minnie so it was easy to turn to them again. Theyre made from food safe polyethylene so theyre strong, flexible and prevent any toxins reaching the breastmilk; the bags can be recycled and theyre designed with double seals to prevent leaks and a gusseted bottom allows for expansion. I lie them flat in the freezer but you can also stand them up! May I add that Betsy is a ridiculously stubborn bottle refuser; please pray for a miracle so that all this effort isnt in vein ????
