What I Loved:

Let’s start with what makes the Souper Cubes MyMilk stand out in the often-overlooked world of breast milk storage. This tray isn’t trying to be everything to everyone; it’s built for a specific, messy job-and it handles the core of that job very well.

Standout Safety: Platinum Food-Grade Silicone

The 100% pure platinum food-grade silicone is the foundation here. It’s BPA, PVC, and phthalate-free, and Souper Cubes mentions rigorous annual testing. For parents, that translates to peace of mind. You’re not just freezing milk; you’re storing it in a material that’s certified safe for direct food contact, which is non-negotiable for baby gear.

Real-World Convenience: The Cube System and Lid

Each tray has 16 wells, each holding 1/2 oz (15 mL) of liquid. That small cube size is brilliant for portion control, especially when you’re mixing fresh and frozen milk or starting solids. The airtight latching lid is a game-changer-it genuinely minimizes leaks in the freezer or diaper bag, something disposable bags often fail at. Plus, the steel-reinforced rim adds heft, so the tray feels sturdy when you’re carrying it.

Versatility Beyond Breast Milk

While designed for breast milk, this tray shines for baby food purees, too. The cubes pop out cleanly once frozen, and their size is perfect for blending into meals or storing homemade blends. They’re also oven-safe up to 415°F and dishwasher-safe, making cleanup a non-issue after a long day.

Eco-Friendly and Space-Saving Design

The reusable nature is a huge win. Over time, you save money on disposable bags and reduce plastic waste. The trays measure 7.25′ L x 6.75′ W x 1.75′ H and stack neatly, which is a small but meaningful detail for maximizing freezer real estate in a packed kitchen.

The Good to Know:

Durability Considerations

The lid’s latch mechanism has received mixed feedback on durability. Some parents find it secure, while others report flimsy latches that can break with frequent use. It’s not a deal-breaker, but it’s worth handling with care. Value perception is split-some see the price as fair for the quality, while others wish it were more affordable for a 2-pack.

Bottom Line:

The Souper Cubes MyMilk delivers on its core promise: a safe, reusable, and convenient way to freeze breast milk. It’s a solid pick for parents prioritizing eco-friendliness and portion control, though be mindful of the lid’s durability over time.

How We Evaluated the Souper Cubes MyMilk Breast Milk Freezer Tray

We didn’t run a months-long freezer trial in a home kitchen. What we did: triangulated Souper Cubes’ published specifications, aggregated owner feedback where available, and mapped the tray’s features against the real-world needs of breast-feeding parents. This review is built around three decision questions-does the MyMilk tray deliver on safe, leak-proof storage, who is it genuinely built for, and who’s better served looking elsewhere? We pressure-tested it across four evaluation dimensions: material safety, convenience in daily use, durability signals from owners, and overall value for the intended buyer. Our goal is to help you decide if this fits your situation, not to crown a universal best.

Is the Souper Cubes MyMilk Breast Milk Freezer Tray Right for You?

1. Who the Souper Cubes MyMilk Is Built For

This tray is a natural fit for eco-conscious parents who want to reduce plastic waste from disposable breast milk bags. It’s also ideal for those who value precise portion control-the 1/2 oz cubes make it easy to thaw only what you need, minimizing waste. If you’re pumping regularly and prefer a system that’s reusable and easy to clean, the MyMilk aligns well with your routine.

2. Who Should Skip the Souper Cubes MyMilk

Skip this if you primarily need bulk storage for large volumes of milk-the 8 oz per tray capacity might feel limiting. It’s also not the best pick if you’re on a very tight budget and prefer the lower upfront cost of disposable bags. Parents who prioritize absolute durability in every component might want to consider the lid feedback carefully.

3. Key Features to Understand Before Buying the Souper Cubes MyMilk

Material Safety: The platinum food-grade silicone is independently tested and free from harmful chemicals, which is critical for baby products.

Lid Design: The airtight latch aims to prevent leaks, but handle it gently to avoid wear over time.

Cleaning and Compatibility: Dishwasher-safe and oven-safe up to 415°F, making it versatile for various foods and easy to sanitize.

4. Setup and Real-World Use of the Souper Cubes MyMilk

Out of the box, the trays are ready to use-just wash them before first use. To freeze breast milk, pour it into the wells, snap on the lid, and place it flat in the freezer. Once frozen, the cubes pop out easily and can be transferred to storage bags or containers. The included storage guide magnet is a helpful reference for new parents navigating safe milk handling times.

Frequently Asked Questions

1. Is the Souper Cubes MyMilk Breast Milk Freezer Tray worth the money?

For parents who plan to pump long-term and value reusability, yes, it can be worth the investment. The MyMilk tray saves money over time compared to disposable bags and reduces environmental impact. However, if you only need occasional storage or prefer the convenience of bags, the upfront cost might not justify it.

2. How do the frozen cubes release from the Souper Cubes MyMilk tray?

The flexible silicone design allows you to push from the bottom of each well, and the cubes typically pop out cleanly. Some users find running warm water on the back helps if they’re stuck, but it’s generally straightforward.

Durability is mixed based on owner feedback. Many find the lids secure and sturdy, but some report that the latches can become flimsy or break with frequent use. Handling them carefully can extend their lifespan.

5. Can the Souper Cubes MyMilk be used for foods other than breast milk?

Absolutely. The trays are excellent for freezing baby food purees, homemade broths, or even juice cubes for older kids. The food-grade silicone and oven-safe rating add to their versatility.

6. How does the Souper Cubes MyMilk compare to similar breast milk freezer trays?

Within the category of reusable silicone trays, the MyMilk stands out for its specific focus on breast milk storage with features like the airtight lid and portion-sized cubes. It’s more specialized than generic ice cube trays, but it competes well on safety and convenience against other dedicated options.

Final Verdict

The Souper Cubes MyMilk is a thoughtfully designed tool that solves real problems for pumping parents. Buy the Souper Cubes MyMilk Breast Milk Freezer Tray if you want an eco-friendly, reusable storage system with excellent portion control and leak-resistant features.
