A MUST HAVE if you have an older child and newborn (or twin newborns)!

Let me start off by saying I DO NOT HAVE TIME TO WRITE REVIEWS. I am a mom to a 2.5 year old and 2 week old twins. But this pump has been such a lifesaver that I have to urge anyone contemplating purchasing this pump to just do it! I literally could not pump if I had to be plugged into a wall, as my toddler is a wild man and does not sit still at all ever. I didn't expect to use this pump as much as I did with my first since I'm not going back to work this time around. BUT I have already gotten more use from this thing than I anticipated because one of my twins had trouble latching so I had to pump for him while nursing the other. There is no way this would have been possible without using this pump. I cannot stress how convenient it is to be able to chase a toddler, change a diaper, nurse a newborn, clean bottles, etc. all while pumping. The Willow has allowed me to begin building a small freezer stash of milk, which has been a huge relief for middle of the night feedings when I've been feeding the twins forever and just need to let my husband give them a bottle. If you are a new mom who has older children, put this pump at the top of your must-have list. You will not regret it. Also, my insurance is through blue cross (Montana) and they fully reimbursed the cost of the pump.

It’s been worth every penny.

These pumps have made my life so much easier; I’m an exclusive pumper. I’m 10 months in and wish I had bought this pump sooner. I love the fact that I can move around and pump anywhere. They seem to be comfortable for the most part and they empty me so much quicker than my regular pump. I also find that I get more milk with these pumps than with my regular pump. I love how compact everything is for these pumps.

Love the freedom!

I love the freedom that this pump provides! It is completely worth the cost. They are truly hands free, and very easy to put on/use (watch the videos available with the app; they're really helpful!). I feel like the pumps do at least as well as my Medela, though my sessions with the willow tend be a bit longer (maybe because I'm not watching every minute tick by, waiting to be able to get up). On the negative side, I must admit the equipment is pretty pricey. I wanted the reusable cups ($50 a set), and I didn't want to wash them every night...so I bought two sets. The bags aren't cheap either. It adds up.

However, it is still a fantastic choice for a pump and I would definitely recommend it!!!

An essential for working moms

I had my first daughter five years ago. I ended up exclusively pumping for her with an older style Medela pump, and would spend hours tethered to my bed or the bathroom at work pumping for her. It’s amazing how much can change in a relatively short amount of time. I just had my second daughter two weeks ago, and had purchased a willow in advance of her birth after doing a lot of research to carefully select a pump. Unfortunately my insurance did not pay for the willow, but did pay for a spectra S1. I decided the ability to pump hands free was worth the extra out of pocket cost for me to get the willow as well. Three days postpartum I developed painful mastitis, and had to use a pump to aid in recovery. I can’t say enough about the difference between the willow and spectra S1. Not only was I able to pump more milk more efficiently with the willow, which allowed for tremendous relief from engorgement, but I was able to get other things done like laundry, work projects, etc all while pumping. This is a huge step forward for working moms to be able to regain this time.

Additionally, I find the app a great resource for troubleshooting, learning assembly, etc. My only critique is that the milk containers can leak easily if you forget to flip the switch from 1 to 2 (which is easy to forget at 3am) and the leftover milk in the flex tubes can spill and get messy. Overall, though, I am generally amazed at how well this pump works, how much time it saves, and what a far superior user…
