Elvie vs Willow Pumps: Choosing the Best Breastfeeding Gadget

Last Updated: 18 March 2022
 best breast pump

Before leaving the maternity ward, the nurses told us that the best way to increase milk supply is to pump. They explained all about extraction, etc., but we can't say that we listened. The idea of being hooked up to some kind an apparatus to extract milk didn’t seem like something we would do. We found it strange that any woman would because it sounded as if it is implied that women become reduced to milk supplying machines when they become mothers. But our baby was our world! So we figured - let’s try breastfeeding, and then try formula if things won’t be well.

We also asked our friend Julie for help and being a mother herself, she said something along the line: “But, you DO know that breast milk is a better food option than any formula? Even World Health Organization said so. Why don't you try pumping instead? There must be some models that will not make you feel weird". She used a wearable breast pump when feeding her younger son. Moreover, Julie told us that these new models of hands-free breast pumps became a big hit recently, and all the busy moms are using them. After thinking about it, we decided to give it a go and started looking for the best breast pump. It turned out she was telling the truth. It became such hype that the market is expected to grow at 8.2% CAGR. Our minds and eyes were stuck on two models Elvie and Willow! These two gadgets appear to be almost identical. However, some differences can play a defining role when investing.

What Are Wearable Pumps and Are They Worth it?

 What Are Wearable Pumps and Are They Worth it

We can say that the best hands-free breast pump is a real game-changer, and here is why. We know that there isn’t healthier food for the little ones than breast milk. And the American Academy of Pediatrics claims that we should breastfeed at least during the first year of a baby’s life. And if you opt for breastfeeding be prepared that it will take between six and eight hours per day. Pumping will take even more. This is quite intimidating, isn’t it? However, it doesn’t need to be, but you need a wearable pump.

Wearable pumps are breast pumps that you can wear under your clothes and do whatever you want or need to do during the time they extract the milk. You can use them when working, traveling, reading a book and enjoying time with your friends. And to get as much comfort, you need only the best pumping bra. There are several models out there. However, we chose today to talk about the similarities and differences between Elvie vs. Willow. We will also mention some breast pumping tips.
