Gen 2 Love

I love my Gen 2 Willow! I would not be able to have a huge stash for my little one without Willow! Way too busy to be attached to a wall or deal with weak pumps, and Willow solves all of that!

Pumped about this pump.

I did a lot of research when it came to choosing a pump as a first time mother. I am so glad I went with the Willow. It's so nice to have the freedom to move around, track progress on an app, and minimal parts to clean. Not to mention the product was created by a team of boss ladies. While it's a bit of learning curve, the coaching sessions* have been very helpful—these gals want you to succeed! Keep up the amazing work.

*I had one over the phone and one over FaceTime with both reps following up afterwards for updates on progress.

A Bumpy but Successful Road

I had previously reviewed Willow as 50/50. At times it worked and other times it didn’t. That all changed after a Coaching Call with Jamie! We did a FaceTime session where we measured my size and she gave me a few tips on how to wear the pumps differently.

It was 100% worth it. I’ve had these pumps for a month and am now yielding the same if not more milk than before with no pain!

I get so much done with this pump and no longer worry about having enough milk for the next day.

Changed my breastfeeding journey!

I honestly fully credit this for the reason I’ve currently almost mad it to 6 months of breastfeeding my first child! I went back to work for about a month without it. I wasn’t able to spend nearly the time I needed to in order to give my little guy what he needed. I saw my supply decreasing and I was truly doing all I could think of. I’m a “just enough”-er as it is and it absolutely broke my heart! I ordered this pump as kind of a last effort because I had to try it. I want to at least get him through cold/flu season and then we’ll see where the journey takes us. After I started using the Willow, and made it through the learning curve, I’m so incredibly happy! My supply returned, I’m able to pump more and still get my work done and when I’m home with my little guy I can still give him all the attention he needs without having to unhook, unplug, etc. Not to mention, when he’s nursing he doesn’t despise the fact that I’m wearing it. I think with traditional pumps you have to sit up so straight, have a bottle or bag dangling, he wasn’t comfortable, I wasn’t comfortable. Life is just seriously so much better! I recommend this pump to anyone that will listen, I absolutely love it and I know I wouldn’t have made it this far without it!! 100% worth it!!!
