Siliconen Moedermelk Bewaarzakken

The silicone feels thicker than the disposable bags I used before, and I like that I can squeeze out every last drop without worrying about a seam splitting. They wash up fine in warm soapy water too, so I've stopped buying the throwaway kind altogether.

These bags actually stand up on their own once filled, which sounds small until you're juggling a pump and a crying baby at 2am. The zip seal clicks shut and I've never had one leak in the cooler bag.

The silicone is thicker than the disposable bags I used before, so I'm not worried about them splitting in the freezer. They stand up on their own while I'm pouring, which sounds small but makes the middle-of-the-night pumping sessions way less messy.
