Milkies Milk Trays

Milkies Milk Trays

Let’s face it – pumping and storing breast milk takes effort. It is a labor of love, of course, but hard work nonetheless. But, if pumping and storing your breast milk helps you reach your breastfeeding goals and allows your child to have your breast milk for as long as possible, it is worth every bit of effort, right? Milk Trays, a breast milk freezing system, can help to make this chore easier. At first glance, Milk Trays look similar to typical ice cube trays. But, take a closer look and you will see that Milk Trays are much, much more. Unlike ice cube trays, Milk Trays are specifically designed for expressed milk. Most importantly, Milk Trays are made from PET plastic, a food-safe plastic that contains no bisphenol-A (BPA), phthalates, or dyes. Milk Trays freeze your milk in 1-ounce “Milk Sticks” that fit through ALL bottle openings and allow you to thaw just the right amount of milk for each feeding – so that not a drop of your “liquid gold” goes to waste. Milk Trays have fitted lids that protect your milk while it freezes and allow for space-saving stacking in the freezer, and the trays are flexible enough to allow the Milk Sticks to be removed easily.

Main features

  • Each tray freezes eight 1-ounce “Milk Sticks”, allowing you to thaw the exact amount you need for each feeding
  • Trays are made from food-grade plastic that is free from bisphenol-A (BPA), phthalates, and dyes
  • Milk Sticks fit in ALL bottle openings
  • Manufactured in the USA
  • 100% reusable and recycleable

Better then anything else

I have had no problems with this product. I see what other reviewers mean about being careful when putting this in the freezer so it doesn’t spill…but then again, I think its always like that when putting ice trays or anything else in the freezer. I was able to get around that by not filling the trays up to the brim, after that I didn’t have the same problem with spills when putting the cover on. I think that this is better then any other option I found for freezing milk.

Give them a try

I used the standard milk storage bags all through nursing my first child, and they were fine. My biggest complaint was that the quantity frozen in the bag often didn’t match the quantity I wanted in the bottle! So, when I saw these trays they looked like a good solution to that issue.However, after ordering the trays, they sat in the box for a month because I was hesitant to mess with my old system for pumping/freezing. Finally I took them out, washed them, and started to use them. It took about a week for me to get into a groove with them, but now that I am, I can’t believe I ever went without them! They rock!Here’s what I love:-milk freezes much faster-you can freeze milk at any time (no waiting to have the right quantity you want to make up a bag)-milk easily pops out of trays and into a regular freezer bag to store-these save $$! Because you can use regular freezer bags, these cut your milk storage costs and will pay for themselves-you can easily get just the amount of milk you want for a bottle-they wash up quickly & easily between uses (hand wash only!)My tips/what I’ve learned:-It’s true the cover doesn’t fit snugly onto the tray, but it’s not designed to. Just be careful when placing the tray in the freezer and it’s not an issue. I put mine in our chest freezer and just created one nice, level spot in a basket to place the tray while it’s freezing. Not a big deal.-Don’t overfill the trays. There is a clear line in each compartment underneath the top. Don’t pour the milk in past that line. This gives the milk a little room to expand as it freezes and you won’t have the spillage/leaking issues as long as you keep the tray level.-I use gallon ziploc freezer bags to store the milk sticks. I just write the month on the bag and then bag 1, bag 2, etc. as I fill them up.I highly recommend these. Don’t listen to the negative reviews. Try them for yourself and see if they work for you. Personally, I can’t imagine these not making your pumping/milk storage life easier!

Generally a good product

I have been pumping and storing breastmilk for 2 months and like these trays a lot. They are convenient and easy to use. To address some of the cons: No, the lids do not snap on tightly, but if you are careful when moving them and lay the trays flat in the freezer you don’t lose any milk. Freezer burn isn’t an issue since I transfer the milk to freezer bags once frozen, and I don’t think these were intended for long term storage, since they do not hold much.Someone said once frozen, they are hard to get out of the trays. I haven’t found this to be the case. Once frozen, I let the trays sit a minute or two out of the freezer, give the tray a little twist and then empty the tray into the lid on the counter, if stuck I pop a stick out by inserting a knife at the end the cube. I then place them into quart sized ziplock baggies for long term storage.The sticks fit into bottles easily, if broken in half. I can get 4 oz into a 9 oz Avent bottle for thawing.

Leaks, cubes too long

This product seemed like such a great idea. And it kind of is, but it is poorly executed. First off, it isn’t dishwasher safe. Unlike most baby things, it cannot handle high temps so it shouldn’t be boiled before the first use and you have to hand wash it. Of course there are no instructions about boiling before the first use and I had to go on their website to find out. Had I gone with my gut I would have ruined them. Not a deal breaker, but dishwashing is more convenient. Secondly, the lids don’t snap on like it seems they would. They just sort of sit on top and leak like crazy if the trays get tilted at all. I have a drawer style freezer and opening and closing the drawer is enough to make it spill so I only fill the cubes abut 1/2 full. Third, the cubes are really long. In the 4 oz bottle size all the bottles were too short to fit them in. I could break them in half but then I would only get half the milk in. The only bottles tall enough are the thin dr brown bottles (thankfully this is the only kind my son likes anyway). If you are using 8 oz bottles then I guess you are fine, but that is more milk than we needed. Finally, the shape is not as convenient as it seems. I can get three to fit if u really cram them in, but they don’t touch the sides of the bottle so getting them to melt in a hot water bath takes forever. I think I am going to switch to freezing milk in bottles. No more fuss. Oh, and a good trick to getting them out of the tray is using a butter knife to loosen the two short ends and then prying them out. They tend to jump onto the counter but no biggie. Bottom line, I feel like I wasted my money and I would not buy again or reccomend to a friend.

Great way to save milk!

I love the fact that milk is frozen in one ounce quantities. This means you thaw out exactly what you need…you never waste an ounce! You do have to wash by hand, and sometimes it’s difficult to pop frozen milk out of the tray, but overall I like it much more than the plastic bag storage systems that are more common. It is also much more environmentally friendly, since you can store many ounces of frozen milk in quart ziploc bags instead of throwing away milk storage bags every three ounces.

tray feels low quality– but it does what it’s supposed to.

I *love* this system for freezing/storing breastmilk.That said, this tray feels low quality. The lids don’t snap on, and I end up spilling milk all over in the freezer– usually just a little– fairly often. The product would benefit from some sort of gutter system around the edge, because it leaks if you hold it just a couple degrees off of level.

Great concept, works well

I like these trays- easy to use, makes small quantities of frozen milk that can be placed in freezer bags (I use the Lansinoh bags or quart freezer bags as the label suggests). Others complained the lid is not tight- but if I don’t overfill the slots and carefully place it in the freezer, I have no issues. I do have problems getting the cubes out, though. I have to turn the tray upside down, let it thaw a minute or so and push/pull out each cube. Even so, I find these much less frustrating than the Lansinoh freezer bags, I spill less milk with these.

Good Product, Could be better

Great milk storage. In the first month of pumping I kept running out of milk storage bags and quickly realized we needed a better system. These milk trays are great. They could use some improvement tho. The lid just sets on top of the bottom and doesn’t keep the milk from spilling. You have to be VERY careful when moving the trays as to not spill the precious fluid.I am looking at other ice trays to see if I can find one that will not spill as easily. Would still recommend this product.

Watch out for hot water!

I don’t have any issues with spills, but I have a very short distance between the countertop and the freezer. The sticks are easy to remove by twisting the whole tray.Be careful as we have warped our first set by putting hot water on it to clean. The plastic is quite flimsy (in order to be able to twist it) and it will simply bend and warp if you pour hot water on it.I have bought a second set so I can say I’m satisfied with the product!

Save your money.

These are a good idea – but what a mess! They don’t latch together and you’ll spill milk all the way to the freezer.

I thought these would be the answer because they seem to make so much sense, but they don’t work as well in practice. First of all, while they freeze milk easily, the milk lines stick to one another in the bags, so you can’t choose one or two, it’s all a big clump. Secondly, the milk gets freezer-burn on all the exposed surface area of the milk lines- and I use expensive breast milk storage bags, too. They do not work like you’d want. Maybe if you keep them separated from touching one another in a freezer bag and use them within a short period of time, which many women might do.

Just what I wanted

Works as advertised. Yes, the lid doesn’t fit tight and you have to be careful when transferring it to the freezer. Just go slow and have a space cleared for it.

Jenna Widnoon, PA

Love this

This is so convenient. Especially when you need just 1 or 2 oz of breast milk to mix in the oatmeal/rice. Way better than frozen in a bag with more than 2 oz.

Best breastmilk storage system

I love this product for several reasons:- reusable- BPA free- made in USA- size – 1 oz sticks help with controlling how much milk I use- easy to cleanThe trays are sturdy, but not dishwasher safe – due to the BPA free aspect. The lids are not snug fitting, so you have to be careful when transferring to the freezer. I find however, that if I fill them below the recommended line, the chance of spillage is greatly reduced. It also helps with fitting the frozen sticks into the bottle. To fit more than 2 sticks at the same time I break them into smaller sticks. The frozen sticks fits nicely into quart size freezer ziplock bags, 1 ziplock/1 tray . It is also nice that the trays are being sold as a 2 pack. I would highly recommend it as alternative to the milk storage bags – its a one time expense and you get to control amount of milk you defrost.

Love freezing milk in 1-oz portions

I love how this gives me the ability to freeze milk in 1-oz portions so I don’t have waste. After 3 months of light use (will use daily and update if necessary when I’m back at work full-time), I haven’t had any issues with the fit of the lids.Only real drawback is you have to use 8-oz or larger bottles with wide necks unless you want to defrost the milk in a different container first. And I’m not sure it’s possible to fit 3 frozen sticks into a single 8-oz bottle, certainly not 4, but my child should only be needing 3-oz at a time for a good while still.Regardless, for me it’s worth it to be able to defrost only as many ounces as I need because I REALLY hate pumping and don’t want to end up throwing out something I worked hard to produce.

a few changes could really improve this

If each section could be made a bit deeper (while still keeping the fill line at the appropriate height), the milk would be less likely to spill out of each section. Also, if the lid would somehow snap on, that would make transportation easier. If the container was airtight, that would also improve the product.

Good product

This is a good product and a great idea except they are too long to fit in the smaller 6 oz bottles.

Carlene Signal Mountain, TN

Love it

This tray is great and a better way to freeze breast milk rather than ice cube trays the sticks come off very easily from the trays. , i just use the gallon ziplock bags after I freeze the milk and it stores and organizes better in my freezer. I’m very pleased with this purchase. It arrived two days early from estimated delivery.
