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 pump is quiet, has excellent letdown and an expression modes, as well as offers multiple adjustable settings.

What’s Included?

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

  • The Spectra S2 pump
  • 2 Spectra wide neck bottles
  • 4 flanges (two 24mm and two 28mm)
  • 2 Spectra backflow protectors
  • 2 Spectra tubes
  • 2 Spectra duckbill valves
  • A 12-volt AC power adapter

One of the things we love this pump is because all the parts that touch breast milk are BPA free, and fully replaceable.

Overview Of Features

Closed system

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.

This 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. It also stops any risk of milk backflowing into the pump. As a mom who’s concerned with the safety of your baby’s milk, this feature is a 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 electric breast pump option

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. Not only does double pumping save precious time, but it’s been shown to increase your milk supply.

But if your little one is hungry and you’re already nursing them, why not use your pump as a single electric and pump milk from the other breast meanwhile? This is a great way to take advantage of letdown and express a little more milk.

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 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.
  7. After your pumping session, you can hand wash and air dry the parts ready for the next time you pump.

Pros and Cons of Spectra S2 Breast Pump

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

  • Allows for single or double pumping
  • Powerful pump motor but still very comfortable 
  • LCD display

Spectra S2 vs Spectra S1

A lot of people will be wondering, what is the difference between the Spectra S1 and Spectra S2? Well, the good news is that there isn’t a huge amount of difference between these Spectra pumps. They are both closed system, hospital grade breast pumps, perfect for exclusive pumpers. They can both be used in single or double pump configuration and they are both closed system pumps.

The main difference is that the Spectra S2 requires wall power and the Spectra S1 has a built in rechargeable battery. Beyond that, the Spectra S2 is pink and the S1 is blue and slightly heavier. You can read more about the differences between S1 and the S2 here.

Spectra S2 vs Medela Pump in Style

The Medela Pump in Style is one of the most popular breast pumps, but it is very different from the Spectra S2. Let’s have a quick look at some of the differences between the Medela Pump in Style and the Spectra S2.

Medela Pump in Style is not a hospital grade breast pump. However, Medela does consider it to have hospital performance. Meaning its suction strength is as strong as pumps used in hospitals.

Both pumps have letdown and expression modes. However, the S2 has fully adjustable suction and speed, which are able to be adjusted independently so that you can find the settings that are most effective for your body. The Pump in Style’s settings only allows you to adjust the strength of the suction, but not the speed.

The Pump in Style comes with it’s own tote bag, where the S2 is a standalone system. Breast pump bags are available that are compatible with the Spectra S2.

Finally on price, the Spectra S2 is a bit more affordable than the Medela Pump in Style.

The Spectra S2 breast pump is an excellent solution for moms worried about low milk production thanks to its hospital grade features, but it’s still very comfortable.

Spectra S2 is a quiet pump, can be used as a single or double pump and offers highly customizable speed and power.

Spectra Pumps are the some of the best pumps on the market, and the spectra S2 is one of the top pumps in 2021. We rate it as the best pump for increasing milk supply because the strong motor can be used over and over again without damaging the motor.
