Overview
The Maymom Breast Pump Bottle is an aftermarket bottle set designed to be compatible with the Medela Pump in Style, one of the most popular breast pumps in the United States. The appeal is straightforward: Maymom offers an 8-pack at $15.49, which works out to roughly $1.94 per bottle, considerably less than purchasing the equivalent volume of official Medela bottles.
Each bottle holds approximately 5.07 fluid ounces, a useful capacity for pump sessions and milk storage. The 8-pack format means parents can pump into multiple bottles throughout the day and refrigerate them without needing to wash immediately after each session, which is a meaningful convenience for working or busy parents. The newborn age range listing reflects that pumped milk in bottles is often used from birth onward.
With 1,900 ratings at 4.6 stars and 200 units bought last month, this is a well-established aftermarket option with a solid track record. Parents researching Medela-compatible bottles will find Maymom consistently surfaces as a recommended third-party option, and the review volume supports that reputation.
Pros
- 8-pack at $15.49 is roughly $1.94 per bottle, significantly less than Medela branded equivalents
- 4.6 stars from 1,900 ratings reflects reliable aftermarket compatibility
- Designed for Medela Pump in Style connector fit, reducing the need for adapters
- Multiple bottles in one pack reduces mid-day washing for frequent pumping parents
Cons
- Compatibility is specific to Medela Pump in Style; parents with other pump brands should verify fit before purchasing
- Aftermarket bottles may occasionally have tighter or looser connector fits than first-party bottles due to manufacturing tolerances
- 5.07 oz capacity is a moderate size; parents who pump large volumes per session may want to look at larger bottles

Performance notes
Based on owner reviews and the product's position as an aftermarket Medela-compatible bottle, the most important performance factor is the connector fit. At 4.6 stars from 1,900 ratings, the vast majority of reviewers report a functional and reliable fit with the Medela Pump in Style. The bottles are plastic and are typically reported as BPA-free for pump-related bottles, though this should be confirmed on the Maymom product page. Leak-proofing during storage is a common concern for pump bottles, and reviewers generally find these satisfactory when the cap is seated properly.
What buyers say
With 4.6 stars from 1,900 ratings, buyer sentiment is strongly positive for an aftermarket product. Medela users who switch to Maymom bottles frequently cite the cost savings and functional compatibility as the primary reasons for satisfaction. A small minority of reviewers note occasional fit variability, which is not unusual for aftermarket accessories. At 200 units bought last month, demand remains active and consistent.

Frequently asked questions
Will these bottles fit other Medela pump models besides the Pump in Style?
The product title specifically mentions compatibility with the Medela Pump in Style. Medela uses consistent threading standards across several of its pump models, so some other Medela pumps may also be compatible, but this is not guaranteed. Checking the Maymom product page for the full list of compatible pump models before purchasing is the safest approach.
Are the Maymom bottles safe for storing breast milk in the freezer?
Many pump-compatible plastic bottles, including those from Maymom, are designed to be freezer-safe for milk storage. However, freezer safety should be confirmed on the Maymom product page or packaging, as not all plastics are rated the same for freezer storage. Leaving headspace in the bottle when freezing is standard practice to account for expansion.
