MyMilk Replacement Lids

Once you have filled your MyMilk tray with breast milk, put the lid on and label the container with the date. Then, place your MyMilk tray in the back center of your freezer. This will ensure that your breast milk stays cold. Freezing breast milk in the freezer door is not recommended because it can have a more variable temperature as you open and close the freezer.

You can keep your frozen breast milk in MyMilk trays for 6-12 months in the freezer, or transfer it to a freezer-safe zippered bag. Storing breast milk cubes in a freezer-safe zippered bag allows you to reuse your MyMilk tray to freeze more breast milk. An additional option for longer-term freezer storage is to transfer your frozen MyMilk breast milk cubes into vacuum-sealed bags.

Be sure to store your oldest milk at the front of your freezer and your newest milk at the back to ensure that you use the older milk first.

Once you have transferred your frozen breast milk portions into a bottle, there are a few different methods you can use to thaw the milk:

1. Put the bottle in a bowl of lukewarm water
2. Place the bottle in the refrigerator overnight
3. Use a bottle warmer

When thawing your milk with water, make sure that the water is lukewarm and not hot to avoid overheating the breast milk.

Each MyMilk tray has 16 half-ounce wells to allow you to freeze a total of 8 ounces of breast milk per tray.

MyMilk trays are made from 100% pure platinum silicone and are BPA-free, dishwasher-safe, and even oven-safe. Our lids are made from 100% BPA-free polypropylene plastic.

We recommend cleaning and sanitizing your MyMilk trays before first use. You can clean them in the dishwasher or in the sink with warm water and soap.

To sanitize, you can:

1. Place in boiling water for five minutes
2. Place in the dishwasher with the sanitize setting on
3. Place in a sanitizing machine

There are two ways to label and date your breast milk. You can either place a piece of our freezer safe kitchen tape on a dry lid and date it with a permanent marker. Or, you can use a water-based paint marker on a dry lid.

Yes, MyMilk trays were designed so that the frozen MyMilk cubes can fit in any baby bottle - narrow-mouth and wide-mouth.

MyMilk trays are manufactured in China, in a factory that pays fair working wages to its employees. All of our trays are tested multiple times a year through third-party laboratories to confirm that they are made with 100% pure platinum silicone, exceed US FDA standards for food safety, and are BPA-free, CA Prop 65 compliant, and CPSIA compliant.

Yes, MyMilk trays are designed to be endlessly reusable. Once Michelle, the creator of MyMilk, stopped pumping breast milk for her son, she started using MyMilk trays to freeze purees and soft foods in half-ounce portions as her son Benjamin transitioned to solids. Another alternative use for MyMilk trays is to freeze homemade minced garlic or ginger and homemade herbed butter cubes for the grown-ups in the household.
