Whether you are a first-time parent or a seasoned pro looking to upgrade your milk storage system, this review will help you decide if these trays are right for you.
What Are MyMilk Breast Milk Trays?
MyMilk Breast Milk Trays are specially designed silicone trays that freeze breast milk into individual, easy-to-pop-out sticks. Each tray holds multiple compartments that each hold about 1 ounce of milk—a common feeding size for many infants. The trays are made from 100% food-grade silicone, which is BPA-free, phthalate-free, and safe for freezing breast milk.
Unlike traditional ice cube trays or plastic freezer bags, MyMilk trays offer a streamlined system. After freezing, you can pop out the milk sticks and store them in a freezer-safe container or bag, or you can keep them in the tray with the optional MyMilk Replacement Lids for added protection against freezer burn and odor absorption. The trays are also stackable, making them easy to organize in your freezer.

- Each compartment holds approximately 1 ounce of milk.
- Made from platinum-grade silicone, safe for direct contact with breast milk.
- Compatible with MyMilk Replacement Lids for airtight storage.
- Dishwasher-safe for easy cleaning.
Why Choose Silicone for Breast Milk Storage?
When it comes to breast milk storage, material safety is paramount. Plastic bags can sometimes leak or develop micro-tears, while plastic containers may contain harmful chemicals like BPA. Silicone, on the other hand, is inert, non-toxic, and does not leach chemicals into your milk, even when frozen or heated.
Silicone is also flexible and durable. MyMilk trays can be twisted or flexed to easily release frozen milk sticks without cracking or breaking. This flexibility means you never have to struggle to get milk out, reducing waste and frustration. Additionally, silicone does not retain odors or stains, so your trays stay fresh after repeated use.
- BPA-free, phthalate-free, and PVC-free.
- Non-porous surface resists bacteria and odors.
- Flexible design allows for easy release of frozen milk.
- Safe for freezer, microwave, and dishwasher.
How to Use MyMilk Breast Milk Trays for Safe Freezing
Using MyMilk Breast Milk Trays is straightforward. First, ensure the tray is clean and dry. Pour expressed breast milk into each compartment, leaving a small gap at the top because milk expands when frozen. Place the tray on a flat surface in your freezer and let it freeze for several hours or overnight.
Once frozen, you can pop out the milk sticks and transfer them to a labeled freezer bag or container. For added convenience, you can also use the MyMilk Replacement Lids to seal the tray directly, preventing freezer burn and keeping milk fresh for up to six months. Remember to label each stick or bag with the date of expression to follow the first-in, first-out rule.
When it is time to feed your baby, simply thaw the required number of sticks in the refrigerator or under warm running water. Never microwave breast milk, as it can create hot spots and destroy beneficial nutrients. The 1-ounce portions make it easy to prepare exactly what your baby needs, reducing waste.
- Always wash hands and pump parts before handling milk.
- Use within 4 days of thawing in the refrigerator.
- Do not refreeze thawed breast milk.
Key Features of MyMilk Breast Milk Trays
The MyMilk Breast Milk Trays are designed with the busy mom in mind. Here are some standout features that set them apart from other storage options:
First, the trays are made from high-quality, food-grade silicone that is both flexible and sturdy. Each tray holds 10 compartments, giving you 10 ounces of storage per tray. The compartments are shaped like sticks, which thaw quickly and evenly. Second, the trays are stackable, allowing you to store multiple trays in a small freezer space. Third, they come in a beautiful mint color that brightens up your freezer and makes them easy to spot.
Another great feature is the compatibility with MyMilk Replacement Lids. These lids snap onto the tray, creating an airtight seal that protects milk from freezer odors and ice crystals. This is especially useful if you plan to store milk for longer periods or want to avoid transferring sticks to bags.
- 10 compartments per tray, each holding 1 ounce.
- Stackable design for efficient freezer organization.
- Airtight lids available separately for long-term storage.
- Dishwasher-safe for effortless cleaning.
MyMilk Trays vs. Traditional Breast Milk Storage Bags
Many moms wonder whether they should use breast milk storage bags or a reusable system like MyMilk trays. Bags are convenient for travel and take up minimal space when empty, but they have downsides. Bags can leak, are prone to tearing, and are single-use, which generates plastic waste. They also require careful handling to avoid contamination.
MyMilk Breast Milk Trays, on the other hand, are reusable for years, making them more eco-friendly and cost-effective in the long run. They eliminate the risk of bag leaks and make portioning effortless. The only trade-off is that trays take up more space in the freezer compared to flat bags. However, their stackable nature helps maximize space, and the convenience of having pre-portioned sticks often outweighs the space consideration.
For moms who pump regularly and store milk at home, MyMilk trays are an excellent investment. They simplify your routine, reduce waste, and give you peace of mind knowing your milk is stored safely.
- Reusable silicone vs. single-use plastic bags.
- No risk of bag leaks or tears.
- Easier portion control with 1-ounce sticks.
- More environmentally friendly.
Tips for Getting the Most Out of Your MyMilk Trays
To extend the life of your MyMilk Breast Milk Trays and ensure safe storage, follow these simple tips. Always wash the trays before first use and after each batch. They are dishwasher-safe, but you can also hand wash them with mild soap and warm water. Avoid using abrasive sponges that could scratch the silicone.
When filling the trays, leave a small gap at the top of each compartment to allow for expansion. This prevents the tray from bulging or cracking. If you are using the MyMilk Replacement Lids, make sure they are snapped on securely before placing the tray in the freezer. Label the lids or the tray with a marker to keep track of dates.
Finally, consider using the No Mess Serving Spoon or No Mess Serving Utensils from Souper Cubes to scoop out frozen milk sticks without touching them directly. These utensils are designed to fit perfectly with Souper Cubes products and help maintain hygiene.
- Wash trays thoroughly before first use.
- Leave headspace in compartments for expansion.
- Use airtight lids for long-term storage.
- Label sticks with dates for easy rotation.
