Willow® 3.0 48-Count 4 oz. Spill-Proof Breast Milk Bags

The bags are amazing. Such a convenient way to pump and store! I love the bags and the whole Willow system.

I love not having to worry about leaks or spills with the bags. I do feel like it's hard to mix the milk and fat back together in the bags when they separate during storage, so I tend to just pour the milk into a bottle right away since I don't produce enough to freeze anyhow.

Convenient for on the go pumping. I always get about .3-.5 less than what the pump says. Can also register wrong and fill with air. When doing flip to finish, gets too much air in the bag to truly use them as freezer bags. Also wish there was a larger option but at 4.3oz it's pushing the pump apart.

The bags are well made, but expensive. Every now and then I'll get one with a faulty valve. I also find that cutting and pouring from the top (i.e., around the valve) is extremely slow. I usually just cut the bag somewhere.

Great concept, but will with air and do not store in a compact fashion. Also unreasonably expensive

They are spill proof if the flip to finish works. Which most of the time it doesn’t. Plus it sucks air into it. How is that good for when you freeze milk unless you transfer them to another container and waste the bag

It’s very convenient that I don’t have to add my pumped milk into containers or bags after pumping. However, I wish there was an easier way to open the spill-proof milk bags, as I don’t typically carry around tools to cut the bag open.

Wish I could rinse the inside before use because they have a chemical smell
