As a nursing mom, sometimes you can’t help but wonder if you’re producing enough milk to keep up with your baby. 

Breast milk is loaded with nutrients for healthy development, immunity, and growth, and it’s a natural way for you to save thousands of dollars that you’d otherwise spend on baby formula.

Unfortunately, frequent breastfeeding is a lot of work which is why many moms turn to breast pumps for help. Breast pumps are a fantastic way to supplement breastfeeding. Whether that is through increasing your supply, helping to maintain supply while you’re away from your baby, or exclusively pumping.

The thing is, pumping breast milk is no piece of cake either, especially if you’re dealing with low milk supply. 

Luckily, the Spectra S2 breast pump offers an effective solution to meet the feeding demands of your hungry baby while keeping the process effortless for your comfort.

Spectra S2 Breast Pump Overview

The Spectra S2 breast pump is a compact breast pump that’s electrically powered to encourage let down and draw milk from the breast. It’s specifically designed to help moms dealing with decreased breast milk production.

The Spectra S2 is a hospital grade pump that remains surprisingly gentle despite its strong motor. This machine is a closed system that operates quietly, has a letdown and an expression mode, as well as offers multiple adjustable settings.

What’s Included?

The Spectra S2 electric breast pump set includes the following items:

  • The Spectra S2 pump
  • 2 Spectra wide neck bottles

  • 2 Spectra backflow protectors
  • 2 Spectra tubes
  • 2 Spectra duckbill valves
  • A 12-volt AC power adapter

Overview Of Features

Closed system

first of all, the Spectra S2 is a closed system. This means a lot of benefits when it comes to hygiene. If you’re worried that some drops of your breast milk will make their way to the motor or other parts of the pump that rarely get cleaned, you can ease your mind with the Spectra S2.

The fact that it’s a closed system ensures that your milk will remain only where it’s intended to be in the pump. This prevents the formation of mold and build-up of bacteria, eliminating the risk of your breast milk getting contaminated without you realizing it. As a mom who’s concerned with the safety of your baby’s milk, a closed system is a huge plus.

Quiet Operation

Most electric breast pumps are usually loud and let their presence be known. However, if you’re returning to the workforce or typically plan your pumping sessions at night, the Spectra S2 offers a notably quiet pumping experience – operating at 45 decibels only! 

While some moms don’t mind a louder pump at work or around family/friends, other moms prefer to keep their pumping under the radar. Let’s face it, there are lots of immature people out there (whether at work or in public places), and receiving comments from such individuals can be a bit embarrassing or even offensive.

Even if you simply like your privacy, the quiet motor on the Spectra S2 will surely make you feel more comfortable expressing milk wherever you need.

Double or single breast optio

Another practical aspect of this electric pump is that you can use it to pump one single breast or both breasts at the same time! While pumping, it’s a smart idea to just do both breasts at once to save precious time. But if your little one is hungry and you’re already nursing them, why not hook yourself up to the pump and pump milk from the other breast meanwhile?

Massage mode

If you need help to kick things off, the Spectra S2 offers a massage mode for this exact purpose. Massaging your breasts is a great way to stimulate letdown as it alerts your body that it’s time to let the milk start flowing. Of course, you can massage your breasts manually, but allowing this machine to do all the work while you sit back and relax just is a lot more convenient.

Adjustable speed and suction

Finding the sweet spot of suction and speed can be difficult with conventional pumps, but it’s much easier when you have customizable settings as in the Spectra S2. You can adjust the suction both in the letdown mode or expression mode according to your body’s unique response.

A night light

Last but not least, the Spectra S2 breast pump is equipped with a night light that gives you better visibility in the dark so you can see what you’re doing. 

This is particularly helpful for new moms who are often sleep-deprived and stumbling around in the middle of the night trying to feed their babies. If you’re also getting up to pump every few hours in an attempt to stockpile enough milk for your growing baby, a nightlight can be a handy lifesaver.

How to Use The Spectra S2

Spectra offers a comprehensive manual that you can easily download or print, but to get you started, here’s a simple step by step breakdown of how to use the S2 electric pump:

  1. Before the first use, sterilize all the components except for the pump motor and tubing by placing them in boiling water for 5 minutes. Allow to air dry completely.
  2. Press the valve into the bottom of the breast shield then twist the breast shield onto the collection tube. 
  3. Press the backflow protector into the breast shield.
  4. Connect the tube to the pump and connect the other end of the tube to the backflow protector.
  5. Place the breast shield so your nipple is centered within the flange. While pumping, you shouldn’t feel any pain.
  6. Try out different settings to find out what works best for your body response. The lower settings are often better.

Pros & Cons

Here’s what we love about the Spectra S2 breast pump:
