When I first started pumping, I never expected that breastmilk storage bags would become such a big part of my daily life. But soon enough, I had a drawer full of them—and after all the effort it takes to fill those little pouches, tossing them after one use just felt… wrong.

So I started wondering: is there a way to reuse breastmilk storage bags that actually makes sense? Turns out, yes—lots of ways, in fact. Some are practical, others a little outside the box, but all of them helped me cut down on waste and keep things a bit more organized in the chaos of parenting.

Kitchen and Food Storage

Honestly, the kitchen is where my reusing habits really took off. I mean, these bags were made to hold food, right? It’s not a huge leap.

Baby Food and Snacks

Once my baby started eating solids, I realized these bags were perfect for storing purées. I’d make a batch of carrots or sweet potato, divide it into bags, and freeze them flat. When I needed one, I just thawed it, snipped a corner, and squeezed it out—easy peasy. No digging around for containers or dealing with clunky lids.

I even started using them for snacks when we were heading out the door. Grapes, crackers, little finger foods—they all fit nicely, and the bags slide right into the diaper bag without taking up much space. Plus, they’re lighter than plastic containers and way less bulky.

And here’s a gem I stumbled on: the Momcozy Spout Breastmilk Storage Bags. These have a built-in pour spout that makes serving super smooth—no awkward pinching or mess. It’s one of those “why didn’t someone think of this sooner?” kind of upgrades.

Baking and Cooking

I also found myself grabbing old breastmilk bags when I didn’t want to deal with piping bags. I’d scoop in some frosting, cut a little hole in the corner, and boom—makeshift pastry tool. It worked like a charm and saved me from more dishes.

And when I had leftover sauces or broth after cooking? Into the bag they went. They froze flat and stacked neatly in the freezer, which was a win for my already jam-packed fridge.

Travel and Organization

It’s amazing how a simple pouch can make travel less chaotic. I’ve learned to never underestimate a clean, empty bag.

Toiletries and Personal Items

At some point, I started packing travel-sized toiletries into leftover milk bags—and let me tell you, it’s one of those mom hacks I now swear by. They’re secure, easy to seal, and I don’t care if they get a little banged up. Shampoo explosion? Not today.

I also stash things like cotton pads, hair ties, even nail clippers when I’m packing in a hurry. And because the bags are clear, I can find what I need without digging through everything.

Electronics and Cables

Cords everywhere drive me nuts, so now I keep them in labeled milk bags. Chargers, headphones, those random USB sticks that seem to multiply—I just throw them in their own bag and zip it up. It’s not fancy, but it works. I even have one labeled “just in case” for all the little tech extras that always end up at the bottom of my backpack.

Arts and Crafts

You’d be surprised how many craft projects start with, “Hey, what if we used one of these bags?”

Children’s Activities

I’ve used breastmilk bags to create sensory bags—just add water, food coloring, and glitter. Freeze them or use them as squishy play mats. They’re safe, fun, and honestly mesmerizing. My kid can poke at them for a good 20 minutes, which in toddler time is basically a lifetime.

We’ve also cut them up to use in collages, made mini puppet costumes out of them, and even turned one into a DIY snow globe pouch. It’s not always Pinterest-worthy, but we’re having fun—and that’s what counts.

DIY Projects

Sometimes I reuse the bags for practical DIY too. I’ve cut them into stencils for painting, or made little pouches for buttons and sewing supplies. I even tried sealing one with tape to turn it into a snack bag—and hey, it held up!

If you’re into giving small gifts, these can work as personalized gift sleeves. Add a sticker, some ribbon, and you’ve got something a little quirky and totally homemade.

Household Uses

Outside of the kitchen and craft corner, I found a bunch of little ways to reuse breastmilk storage bags that I hadn’t thought of before.

Storage and Organization

Let’s talk junk drawers. Mine was overflowing with paperclips, screws, and… who knows what else. I started sorting things into clean bags—rubber bands in one, safety pins in another—and labeling them. Suddenly, I could find stuff without digging. Wild, right?

I also use them for packing snacks on hikes or for organizing small toys. My toddler loves picking out which “bag of treasures” to bring when we go out.

Gardening and Outdoor Activities

Here’s a weird one that actually works: slow irrigation. I poked a couple of tiny holes in a bag, filled it with water, and left it at the base of a plant. The water trickles out slowly, which is especially helpful when I forget to water for a few days (which is… often).

And for outdoor days, they’re great for tossing in sandwiches, packing wipes, or keeping bug spray from leaking all over everything. They’re lightweight, sturdy, and surprisingly reliable.

Safety and Cleaning Considerations

Okay—real talk. Not every breastmilk bag is meant to be reused, especially the thinner, single-use types. But for the sturdier ones? You can definitely get more life out of them if you clean them properly.

I wash mine with warm, soapy water right after use—before anything dries out or gets crusty (gross, I know). If the bag’s dishwasher safe, I’ll toss it on the top rack. Otherwise, I rinse it well and air dry it upside down on a drying rack.

I’m also careful not to mix up what the bag was used for. If it held breastmilk, I don’t reuse it for snacks or baby food. That just feels like a line I don’t want to cross. Labeling helps here—just a quick note with a marker can make all the difference.

Here’s what my routine usually looks like:

Better safe than sorry, especially when it comes to food safety and little ones.

Conclusion

It’s funny—something as simple as a breastmilk bag can turn out to be so much more useful than you’d expect. Once you start thinking outside the box, it’s easy to find ways to reuse breastmilk storage bags that go way beyond their original job.

From storing baby snacks and organizing cords, to craft-time fun and impromptu gardening hacks, these bags really earn their keep. And while I’ll always appreciate their role in the early feeding days, I’m even more grateful for how they’ve stuck around to make everyday life just a little easier—and a little less wasteful. So if you’ve got a few empty bags lying around, don’t toss them just yet. Give ’em a rinse, get creative, and see what they can do.
