What is the Medela Sonata?
The Medela Sonata is a one of Medela’s higher-end breast pumps.
Medela offers many different breast pumps, each with a slightly different flavor – hospital grade (the Symphony), double electric for pumping at work (the Pump in Style Advanced and Max Flow), portable (the Freestyle Flex and Swing Maxi), single electric (the Swing), and manual (the Harmony).
The Medela Sonata falls somewhere between the Symphony and Pump in Style – it’s a personal breast pump, but it’s a smart pump that can integrate with an app on your phone and the suction/motor is “inspired” by the Symphony.
What are the pros of the Sonata?
Some of the advantages of the Medela Sonata include:
- The Sonata has a rechargeable battery, so you aren’t tied to an outlet when you pump.
- It is a very effective pump – many moms said that it was as efficient as the Symphony (Medela’s hospital grade breast pump), with the added bonus of being much more portable than the Symphony.
- It is a closed system pump, which means no milk in the tubing.
- The Sonata connects to the Medela Family app (available for iOS and Android) to automatically track your pumping sessions.
- Comes with two sets of breast shields (sizes 21mm and 24mm). The breast shields included with the Sonata are Medela’s PersonalFlex flanges, which Medela says are 11.8% more effective than regular breast shields, as well as more comfortable.
What are the cons of the Sonata?
There are also a few disadvantages:
- While the pump is portable and has a rechargeable battery, it is a bit bulky.
- The pump parts the Sonata uses are unique to this pump, so may be difficult to find in a store. (Therefore, you might want to stock up online in case one of yours breaks.)
- It is sold at a higher price point than many other breast pumps.
Medela Sonata Breast Pump Accessories
The breast pump parts are unique to this pump.
- A breast shield connector
- A connector cap
- A valve
- A membrane
One question that comes up frequently with the Sonata is how often the breast pump parts need to be replaced.
Medela doesn’t explicitly define a replacement timeline on their website, but the manufacturer did answer a question on amazon regarding this, stating the following in November 2017:
There is no life expectancy on the parts. We recommend replacing your parts if they are damaged or if they have become worn.
You can also replace just the membranes if you’re concerned about a loss of suction.
The Sonata also comes with PersonalFlex breast shields. These flanges have a 105 degree angle (in contrast to the 90 degree angle other Medela breast shields use) and have softer, silicone edges.
Medela breast shields can be used interchangeably with any Medela pump.
What bottles are compatible with the Sonata?
The Medela Sonata uses regular Medela bottles, which are narrow-mouth bottles. You may be able to screw other narrow mouth bottles into the Sonata pump parts, such as Evenflo or Dr. Brown’s bottles.
If you have wide-mouth bottles you’d like to use with the Sonata, Maymom makes an adapter than you can use to pump directly into AVENT or Spectra bottles.
Medela Sonata or Medela Freestyle Flex?
Both of these are great pumps. Some differences that you may want to consider:
- The Medela Freestyle Flex is much smaller and more portable than the Sonata.
- The Flex is priced slightly cheaper than the Sonata.
- Some women may find that the Sonata is more effective for them than the Flex.
Medela Pump in Style vs Medela Sonata?
Again, both of these are great pumps. The major differences are:
- The Medela Pump in Style does not have a rechargeable battery, so it’s less mobile than the Sonata.
- The Pump in Style is also priced significantly lower than the Sonata.
- The Pump in Style doesn’t have any integrations with the Medela Family app.
Medela Sonata Review: Bottom Line
The Medela Sonata is a great pump for moms who want the effectiveness of a hospital grade pump, but have the ability to use it on the go. It’s a great option for both working moms and exclusive pumpers.
