Best invention ever

If you are hesitant at all to purchase this, don’t! This was the best thing I have ever purchased for my breastfeeding/ pumping journey. I work on an extremely busy floor in a large hospital, so the willow was the answer for me! It is easy to use, and takes only a minute to put on and off. It did take my body about a month to adjust tot he suction so for a few weeks I did need to pump with willow and then a regular pump until my body adjusted because it is a different type of suction. The suction is gentle I can barely even feel it. The noise is minimal, not silent. If there is any background noise around you, you won’t be able to hear it yourself. They do make your bust seem rather large, but this can be easily concealed with a jacket or scarf. 10/10 recommend!

Making pumping and breastfeeding equals

Looked at Willow and Elvie for months. I have a medela freestyle and a spectra s2 from previous babies. Would have gotten a new free pump of my choice again from my insurance. Finally decided to just order Willow even though the bags were a continuing expense and I could have had a free traditional pump.

PROS:

Multi-tasking!! It makes a huge difference to be able to pump while starting dinner or brushing your teeth or picking out clothes or feeding on other side. Yes in theory some other pumps let you multitask-but not without constantly having to make sure you're not leaning too far and going to spill any of your hard earned milk.

Discrete- I can simply turn my back for a few minutes in my kitchen to place the pumps then turn back around and carry on visits. With traditional pumps I would be secluded to my room if guests were around. Yes the Dolly Parton look is not discrete, but if the guests dont have a sense of humor I just pretend I have to go to my room to pump anyways!

Ease of cleaning- Feels like it takes me a much shorter time to clean the pieces.

Customer service- I had an issue with one of my pumps. Super happy to simply text and not have to call or email. We went back and forth for a few days as the pump worked off and on. Eventually they had to replace just one side and I have had no issues since then👍🏼

Covered by HSA- just sent in my order slip and got reimbursed.

I dont loathe pumping it becomes just as easy as breast feeding. Also would be life…
