Mila's Keeper Silicone Breast Milk Storage Bottles are made of 100% LFGB Platinum-Grade silicone. This requires the strictest testing by a third party CPSC-approved lab, meeting EU standards, as medical-grade (different from food grade).

Silicone is an organic based polymer, which is non-toxic and unlike plastic it is very durable, easy to clean and odorless. It is soft, silky and will not stain when washed after each use.

Mila's Keeper prides itself in using the highest quality materials. All components of our products have been tested and exceed all US FDA and CPSC tests for lead, cadmium, Bisphenol A, and phthalates.

Mila's Keeper Silicone Breast Milk Storage Bottles come in two (2) sizes, standard and wide neck, to accommodate different size pumps and nipples.  Make sure you know which neck size is the right storage bottle for you. (Standard is currently on Pre-Order)

*Important notes about use for Feeding:  There are manufacturing variations of many of these brands, therefore we are unable to guarantee that nipples will fit.  Please test nipples for leaks before use.  Also we do NOT recommend its use for feeding past the age when the infant can squeeze the bottle.

The wide mouth of this size also accommodates milk poured from wearable, hands-free breast pumps such as Freemie, MomCozy, Elvie, and Babyation.

Volume: 6 ounces | 180 ml

Weight: Standard: 3.2 oz; Wide: 3.7 oz

Dimensions: Approximately 2.5 inch (63mm) x 4 inch height (105 mm).

Fits conveniently inside the MilKeeper!

Care & Use Instructions

Mila's Keeper Silicone Storage Bottles can be used to directly pump breast milk into using most leading brands of breast pumps, to store breast milk, and to feed.*

In order to secure the leak proof patent-pending silicone lid, there are two ways to use:

1. Push the lid firmly down to the bottom of the mouth of the bottle and twist to tighten, ensuring there is no gap between lid and bottle.

OR the easiest way

2. Simply peel back the lid to open, and push firmly down making sure there is no gap between lid and bottle.  See video here.

*Please note that when you first receive the bottle in its package, the lid might be vacuum sealed making it harder to peel open. Just know that once it is opened the first time, the vacuum will be released and it will be easier to use thereafter.

Use in Freezer & Bottle Warmer

Medical grade silicone is the purest form of silicone which contains no fillers, this means it handles even better under extreme conditions such as the freezer and even boiling water without fear of any leaching chemicals or microplastics which occurs when plastic is heated.

We would like to caution that when doing so, especially boiling, the silicone bottle will be extremely hot and you must use protective gloves to handle the hot glass.

Caring for your bottle:

Be sure to always clean your bottles before first use.

Dishwasher Safe

Yes silicone is fully safe in the dishwasher! We would also encourage a thorough rinse to remove residue beforehand especially in harder to reach places, such as the shoulders of the bottle.

Sanitize

Our bottles may be sanitized in multiple ways - by boiling water, the microwave or by UV sanitizer.
