Jars Made for Feeding and Storage


Volume Markings
Our jars are upgraded with precise volume markings to help parents. Fill the jars past the markings up to near the top of the jar – get your full capacity.


Easy to Clean
Straight sides with no awkward-to-reach parts make our jars easy to clean and won’t leave the stinky stale milk smell. If you’re busy, just pop it in the dishwasher.


Warm Milk Safely Right in the Jar
Take out of storage and prepare your baby’s milk in the same jar. Do make sure to thaw properly if taking out of the freezer – all glass will crack due to sudden temperature changes.


Ideal for Breast Milk and Baby Food Storage
The extra silicone seals inside the storage lids help form an airtight seal to preserve freshness and prevent freezer burn.


Safe to Freeze, Safe to Warm
Freeze breast milk or baby food—or anything really. To reheat a frozen jar, simply thaw on the counter for a few minutes or in a bowl of warm tap water for minute.
All mason jars will break if taken directly from the freezer to high heat (ie bottle warmers, microwaves, etc..) but as long as you thaw the jar first, heat is no problem!


Wide Easy to Clean and Easy to Fill
Regular-mouth mason jars have wide, easy to fill openings. This also makes cleaning a breeze. No bottle brushes or pipe cleaners required.


Upcycle For Years to Come
We intentionally kept branding minimal, mature, and gender neutral so that these jars can last well beyond the baby phase.
Safety First: Our glass baby food jars are made from premium, non-toxic, and lead-free glass, ensuring no risk of micro-plastics, toxins, or chemical leeching. Perfect for storing breast milk and baby food safely.
Airtight Freshness: Each jar comes with a removable 100% silicone ring around the lid, providing an airtight seal to keep contents fresh and prevent freezer burn. Ideal for preserving the quality of baby food and milk.
Space-Saving Stackable Design: The stackable lids make organizing easy and maximize storage space in your refrigerator or freezer. No more cluttered shelves—just neat, stackable jars.
Multipurpose Use: These jars are versatile and multipurpose, easily converting from storage containers to feeding bottles by adding a Mason Bottle nipple. They’re dishwasher safe, easy to clean, and perfect for everyday use.
Precise Measurement Markings: The jars feature embossed 0.5-ounce incremental measurement markings, up to 6oz (180 mL) / 2oz (60 mL), with a full capacity of 8oz / 4oz. Easily track intake and portion sizes.

Came broken and scratched up.
One of them was completely shattered, 2 were chipped and there bits of glass everywhere. Iâll still use the ones that survived once I can be sure Iâve gotten all the bits of glass off of them (Iâve already boiled, and washed in the dishwasher but I still feel grittiness) but Iâm not loving the look of them or the quality as much as I was expecting.
Love these
Work good. Seals fall out of lid sometimes if you dont have them sucked under ththe lid rim but otherwise good
These are great for milk storage! The lids are where my issue lies. There is a small insert inside & it can get moldy if you donât take it out. Also, a couple of the lids have cracked & broken just from washing & using them multiple times.
Me encantaron los frascos, súper prácticos, el tamaño justo, fácil de limpiar, son súper versátiles y los puedes usar para otras cosas y además están muy bonitos
Restos de vidrio pequeño adentro de los frascos.

Great combination of sizes, and oz and ml markers are clearly marked in glass. The lids are plastic, so if you’re trying to avoid plastic altogether you can use metal mason jar lids and rings instead. Mason Bottles also offer adapters for pumping directly into their jars, but we had mixed results. Love that these will continue to be useful long after we’re done bottle-feeding!
