BEST!

All around best best best! I had some trouble at the beginning but I reached out to one of consultants and they helped & me and gave me some tips! Sent me the correct size flanges that I needed and I was set up to go. Once you take your time to get the hang of it, it’s a dream especially for a mama of twins. So nice to be able to pump wherever you go. Worth the money hands down...mamas you want one trust me.

Love this pump!

This pump does have a learning curve! But once you get it i think you’ll love it. I am a veterinary nurse and would not be able to keep pumping if it weren’t for this pump. I’m able to walk around the clinic and get things done while pumping. I’m not cooped up in a room plugged into a wall. So thankful for Willow!!

Simply Amazing

As a physician in a high-volume hospital system, I don't often have time to take 30 minute (or longer) breaks to pump every 3-4 hours. With Willow, I was able to pump on schedule without having to worry about falling behind on work. I could also pump while driving, shopping, or even lying down (critical for those middle-of-the-night 2AM pumps). There was a bit of a learning curve at the beginning, but everything quickly fell into place. Bags are a bit pricey (I had the 1.0, so the new containers weren't an option for me), especially if I only got 1-2oz during the pump, but are also so convenient if you're on the go and don't want to waste time transferring from pump to bag/bottle. I was also able to freeze directly in the bags, which saved me from having to buy bags specifically for that. As long as they weren't too full, they froze pretty flat so I was able to stack them to the ceiling of my freezer. At the time of this review, I've already completed my pumping journey (still direct breastfeeding every day, though), but I don't know if I would have made it to my 1 year goal of EBF without this pump. Although there are other cordless pumps available, my experience with Willow has been so smooth that I hesitate to explore other options whenever my next pregnancy comes around. Why mess with what works?

Best pump ever!

The willow pump is amazing. I’m a mom to 3 kids, one is a very busy 3 year old, and with out willow breastfeeding wouldn’t be an option. You can literally pump while doing anything you want. I love how easy it is to take on the go, and the milk containers are so nice!! I don’t have a single complaint about the willow pump.

Pumped for the Willow!

The Willow pump is an amazing option for Moms at home and on the go. In the first couple weeks, I had been using my spectra, first with no hands-free pumping bra, which I had to immediately rectify. Then I tried the freemie cups so I didn't feel as awkward when we had visitors and I had to cover up (by my own choice) or disappear for 30 minutes at a time. Now I almost exclusively use the Willow. It did take a few trial and error sessions to get things right because it was very painful for me at first, but now I love it. I have the bags for when I'm going to be moving a lot or napping or if I'm out and about and don't want to worry about bringing storage bottles. I also have the containers which are great for me at work or at home so I don't have to purchase as many bags. They are also basically leak free, as long as you don't go upsidedown or jump around like crazy. I've been sharing my experience on my instagram, @pumping4twins if you'd like to see some videos of how to use it in my experience. Highly recommended!
