Willow has given me hope for my breastfeeding journey

As a new mom with low production, it was a struggle to feed my son by breastfeeding alone. The decision to supplement was hard. Trying to pump with a traditional pump was harder, especially after I went back to work. I was ready to give up. And then a friend told me about her Willow. I budgeted and saved and finally bought. And the result was freeing. I don't dread pumping anymore. I don't feel tied down while pumping. Even if I only pump an ounce during a session, I don't feel like a failure because I was able to do other things during it. 25 minutes is nothing now, and after 4 weeks, today I was able to pump nearly 4 ounces for the first time. It seems small, but to me its huge. If nothing else, Willow has given me hope that my breastfeeding journey doesn't have to end.

Issue with my pump

So I had bought these pumps back in August of 2020. Not even 2 month later did I start having trouble with my right pump. For some odd reason the pump just kept giving me an error that the container was closed incorrectly and would not allow me to pump. It was very frustrating to say the least as I use them every day, except weekends. I hate being tied to my other pump, which is why I love that these are mobile! (Although, the only thing I dislike is the fact that if you are small breasted- such as myself- these pumps give you the allusion of having ginormous boobs!)

anyway, I had contacted customer support and they fixed my issue within days! I was truthfully very impressed! I answered all of their questions with as much detail as possible and in TWO days I had a replacement pump! Would absolutely recommend this product to any breastfeeding mom who needs to pump on the go or needs to do things around the house but doesn’t want to have to struggle with wires or being plugged into a wall. I love these pumps! They have made my life so much easier!

Game Changer

I had my first baby in May. I was blessed to have 4 months off with him before starting back to work as an ICU RN. When I returned to work, I quickly realized what a hassle pumping at work was going to be plugged in a wall with a traditional electric breast pump. I began researching hands free options and found Willow. After my research, I decided to make the investment with the Willow pump. This pump is a lifesaver and worth EVERY single penny! My only complaint about the Willow is that I didn’t have it from the day my son was born! There is definitely a learning curve to its use because it’s so different from traditional pumps. If you have any issues, customer service is extremely helpful as well as their help page with videos. Once I figured it out, I am no longer tied to a wall for hours of my life. I will be using Willow for all future babies and recommend anyone that is breastfeeding and pumping to get it!
