What’s in the Box? A Complete Overview of the 16 Piece Set

The MyMilk Breast Milk Trays 16 Piece Set is exactly what it sounds like: a comprehensive kit designed for moms who need to store breast milk in bulk without sacrificing quality or convenience. Each set includes four trays, each featuring multiple individual compartments that hold approximately 1 ounce of milk per cube. That means you can freeze up to 64 ounces of milk in a single batch — enough to cover several days of feedings.

The trays are made from high-quality, food-grade silicone that is BPA-free, phthalate-free, and FDA-approved for direct food contact. The silicone is flexible yet sturdy, making it easy to pop out frozen milk cubes without cracking or spilling. The set also comes with matching lids that snap on securely, preventing spills and protecting the milk from freezer odors. For moms who want extra organization, the MyMilk Replacement Lids are available separately if you ever need spares.

• 4 trays with 16 one-ounce compartments each = 64 ounces total capacity per batch
• 100% platinum silicone, BPA-free and phthalate-free
• Snap-on lids for spill-proof storage and odor protection
• Compact design stacks neatly to save freezer space

Why Pumping Moms Love the 16 Piece Set: Key Benefits

One of the biggest challenges for pumping moms is managing the sheer volume of milk while keeping it organized. The MyMilk Breast Milk Trays 16 Piece Set addresses this head-on. Because each cube holds exactly 1 ounce, you can thaw only what your baby needs — no more defrosting an entire bag only to waste half. This precision is a game-changer for moms who are tracking intake or dealing with a baby who eats variable amounts.

Another major benefit is the tray’s freezer-to-bottle convenience. Once the milk cubes are frozen solid, you can pop them out and transfer them directly into a bottle or storage bag. The cubes are uniform in size, so they fit easily into standard bottle necks. This also makes it simple to combine cubes for larger feedings. For moms who pump multiple times a day, the ability to freeze in bulk and then portion later saves hours of time each week.

• 1-ounce cubes prevent waste and allow precise feeding
• Cubes fit standard bottle necks for direct transfer
• Bulk freezing reduces daily handling and cleanup
• Lids keep milk safe from freezer burn and odors

Design and Material Quality: Built for the Long Haul

Souper Cubes is known for its durable silicone products, and the MyMilk Breast Milk Trays are no exception. The trays are made from thick, high-quality silicone that holds its shape even after repeated freezing, thawing, and washing. Unlike thin plastic trays that can crack or warp, these trays feel substantial and are built to last through months of daily use. The silicone is also non-stick by nature, so frozen cubes release effortlessly with a gentle twist or press on the bottom.

The lids are a standout feature. They snap on with a satisfying click and create a tight seal that keeps milk cubes securely in place. This is especially important when stacking multiple trays in the freezer — you don’t want one tray sliding and spilling its contents. The lids also prevent the milk from absorbing any freezer odors, which is a common issue with open containers. For moms who want a coordinated look, the set is available in several colors, including the popular MyMilk Breast Milk Trays - Pink and MyMilk Breast Milk Trays - Gray.

• Thick platinum silicone resists cracking and warping
• Non-stick surface for easy cube removal
• Snap-on lids create an airtight seal
• Available in multiple colors to match your kitchen aesthetic

How to Use the MyMilk Breast Milk Trays for Maximum Efficiency

Using the 16 piece set is straightforward, but a few tips can help you get the most out of it. First, always wash the trays and lids with warm, soapy water before first use. Silicone can retain a slight manufacturing smell, which a quick wash will eliminate. Once clean, fill each compartment with expressed milk, leaving a tiny gap at the top to allow for expansion as the milk freezes. Snap on the lid and place the tray flat in the freezer.

After 4-6 hours (or overnight), the milk cubes will be fully frozen. To remove them, simply flex the tray or push the cubes out from the bottom. Transfer the cubes into a labeled freezer bag or container, and return them to the freezer. This method frees up the trays for your next pumping session. For moms who pump multiple times a day, having two or more sets in rotation means you always have a clean tray ready to go. You can also use the No Mess Serving Utensils to handle the cubes without touching them directly.

• Wash trays before first use to remove any manufacturing residue
• Leave a small gap in each compartment for expansion
• Freeze flat for 4-6 hours, then transfer cubes to bags
• Rotate between multiple sets for continuous use

Cleaning and Maintenance: Keeping Your Trays Hygienic

Breast milk storage requires strict hygiene, and the MyMilk Breast Milk Trays are designed for easy, thorough cleaning. The silicone material is non-porous, meaning it won’t harbor bacteria or absorb milk residue. You can wash the trays by hand with warm, soapy water and a soft sponge, or place them on the top rack of your dishwasher. The lids are also dishwasher-safe, though hand washing is recommended to preserve the snap mechanism over time.

One common concern with silicone is staining, especially from fatty breast milk. While the trays may develop a slight yellow tint over time, this is purely cosmetic and doesn’t affect safety or performance. To minimize staining, rinse the trays immediately after use and avoid letting milk dry on the surface. For stubborn residue, a paste of baking soda and water works wonders. Avoid using abrasive scrubbers, as they can damage the silicone’s non-stick surface.

• Dishwasher-safe (top rack) or hand wash with mild soap
• Non-porous silicone resists bacteria and odors
• Rinse immediately to prevent staining
• Use baking soda paste for stubborn residue

Comparing the 16 Piece Set to Other Breast Milk Storage Options

When it comes to breast milk storage, moms typically choose between bags, hard plastic containers, and silicone trays. Bags are convenient but can leak, tear, and are single-use, creating waste. Hard plastic containers are reusable but take up a lot of freezer space and can be difficult to clean. Silicone trays like the MyMilk 16 Piece Set offer the best of both worlds: reusable, space-efficient, and easy to clean.

Compared to standard ice cube trays, the MyMilk trays are specifically designed for breast milk. The compartments are the perfect size for a typical feeding, the lids prevent spills and contamination, and the silicone is medical-grade. While the initial investment is higher than a pack of bags, the trays pay for themselves over time since they can be used hundreds of times. For moms who pump for several months, this is a smart, eco-friendly choice.

• Reusable silicone is more eco-friendly than disposable bags
• Compact design saves freezer space compared to hard containers
• 1-ounce portions are ideal for baby’s feeding schedule
• Medical-grade silicone is safer than plastic alternatives

If you’re a pumping mom looking for a reliable, efficient, and hygienic way to store your breast milk, the Souper Cubes MyMilk Breast Milk Trays 16 Piece Set is an excellent investment. It simplifies the process of freezing, storing, and portioning milk, saving you time and reducing waste. Ready to upgrade your pumping routine?
