What is a nursing keepsake?
A nursing keepsake is a tangible way to honor the season of feeding, soothing, and bonding. With DIY by MILKIES®, you preserve a tiny amount of your own breastmilk into resin, at home, so your memory becomes a wearable piece you can hold onto long after the last latch.
Deeply Personal
A keepsake made from your own milk carries the quiet meaning of late nights, comfort feeds, and the bond only you and your baby know.
Pure Preservation
Our patented method preserves breastmilk in liquid form, no drying, no powders, and nothing removed, so what you keep is authentically yours.
Made to Last
Set in professional-grade resin and crafted with quality materials, your nursing keepsake is designed to stay beautiful for years to come.
Why make your own nursing keepsake?
Milk Stays Private
If the idea of mailing breastmilk feels uncomfortable, you’re not alone. This kit lets you keep the entire process at home, your milk, your hands, your space.
Meaningful to Make
Creating it yourself turns the keepsake into a ritual, not just a purchase. Many mothers say the making is surprisingly calming, and helps them process the emotions of this chapter.
On Your Timeline
No waiting weeks for someone else to make it. You do about 30 minutes of active work, then let it cure, so it fits your schedule, not the other way around.
Worth Celebrating
Whether you’re weaning, returning to work, or simply marking a milestone, a nursing keepsake honors what you gave, one small piece that holds a very big story.

Kasia Lew, Mother of 2, extended breastfeeding & tandem nursing
From a nursing season to something forever
Kasia Lew’s journey began in 2013 with the birth of her first child, Adam. As she practiced extended breastfeeding, and later tandem nursing her two children, she came to understand the bond created in this intimate time, and how quickly it becomes “before you know it.”
After months of research and development, Kasia launched MILKIES® on Mother’s Day 2016. What started as a home-based operation grew into an international brand, now serving 70,000+ mothers across 50+ countries with meaningful, wearable keepsakes.
The DIY kit was created by listening closely to customers. Many mothers wanted a nursing keepsake, but felt hesitant about sending breastmilk to a third party. With Kasia’s background in computer linguistics and multimedia, she built an at-home solution: a complete kit with step-by-step video guides.
DIY by MILKIES® is the only kit that preserves liquid breastmilk in resin without altering its natural state. It’s a testament to Kasia’s dedication to authenticity and quality, so your keepsake reflects your real journey, exactly as it was.

A Nursing Keepsake You Can Wear Without Letting Go
The end of breastfeeding rarely arrives with a neat goodbye. A nursing keepsake can hold the tenderness, the grit, and the small midnight victories in a form that doesn’t ask you to explain yourself.
By Kasia Lew, Founder of MILKIES®
The last feed is not a clean ending
The search for a nursing keepsake usually begins in a moment you didn’t plan. It might be a sleepy latch you suddenly realise is becoming rare, a distracted toddler who pops on and off as if they’ve already got one foot in the next chapter, or the first morning your body feels different after a missed feed. You can be ready and not ready at the same time.
Breastfeeding is physical memory. It is a weight in your arms, a rhythmic swallow, the particular hush that falls over a room at 3 a.m. It is also the unseen labour of it all: the planning, the pumping, the sore days, the quiet triumph when something finally clicks. When it begins to fade, many mothers want something that doesn’t reduce it to a single photo or a line in a baby book.
That’s where the idea of a nursing keepsake becomes more than a Pinterest category. It becomes a way of saying, “This mattered.” Not in a performative, shareable way, but in a private, steady way. Something you can reach for on the days you feel sentimental, and also on the days you feel strangely blank.
Yet most keepsakes either live in a box or ask you to outsource the story to someone else. And for something as intimate as breastmilk, that can feel like another demand on a mother’s trust and time.
There is another route: making a nursing keepsake yourself, at home, with materials designed to preserve breastmilk in its true liquid form inside resin. It’s hands-on, practical, and unexpectedly tender. It turns the act of remembering into a small ritual you control.
Why a nursing keepsake can feel heavier than it sounds
Breastfeeding ends in fragments not fireworks
Many mothers imagine a clear endpoint, a final feed that feels ceremonial. More often, weaning happens by inches. A feed disappears, then another. The chair you always used becomes just a chair again. Your body adjusts, your baby adjusts, and your brain tries to catch up. In that in-between, a nursing keepsake isn’t about clinging to the past; it’s about giving the past a place to rest. It can hold the story without asking you to keep replaying it. It also gives shape to a chapter that is frequently minimised. You may hear, “At least you got a few months,” or, “They won’t remember.” But you will. And memory deserves a home that isn’t only in your nervous system.
The pressure to choose the perfect object
There is a strange modern expectation that every life milestone should be captured in the correct artefact. The wrong choice can feel like failure, as if meaning is something you can purchase in the right font. A nursing keepsake works best when it is less about trend and more about truth. The truth is sensory: milk, skin, warmth, time. Keepsakes that honour breastfeeding tend to work when they are tactile and durable, not merely decorative. The object should withstand the ordinary days, because breastfeeding itself was made of ordinary days. A wearable keepsake can meet you in the school run, the commute, the supermarket aisle, without requiring you to open a memory box to access the feeling.
Privacy and control are part of the emotion
Breastmilk is intimate in a way people outside the experience often underestimate. It carries identity and vulnerability. For some mothers, sending milk away to a third party feels straightforward. For others it triggers a hard no: concerns about mishandling, loss in transit, or simply the discomfort of letting something personal leave the house. That’s why the DIY approach has become so important in the keepsake world. A nursing keepsake made at home can be less about craft and more about agency. You decide the timing, the level of focus, the pace, and what happens to the material at every step.
A nursing keepsake that is made not commissioned
Breastmilk jewelry has existed for years, often through send-away services where a creator preserves milk and sets it in resin or stone-like material. The emotional promise is clear: a nursing keepsake that is both personal and wearable. The practical barrier has always been trust and logistics, especially when the milk itself is the irreplaceable ingredient.
DIY by MILKIES® was created for the mother who wants a nursing keepsake but also wants to stay close to the process. After MILKIES® had already processed over 100,000 orders in keepsake jewelry, it became obvious that there was a group of mothers who loved the idea yet hesitated to mail their milk to anyone at all. The answer wasn’t to pressure them. It was to design a kit that made professional-level preservation possible at the kitchen table.
As the founder, I came to this with the same layered feelings many mothers carry. I practiced extended breastfeeding and even tandem nursing my two children, living through the way these seasons shape your identity and then slip away before you are ready. My background in computer linguistics and years running a multimedia agency taught me something surprisingly relevant: clarity matters. When emotions are high, instructions must be calm, precise, and human.
So the kit is built like a guided workshop. It includes a step-by-step video guide, a large workmat that organises every stage, and all necessary tools and components. You choose your jewellery setting first, because your nursing keepsake should match your life, not the other way around: four necklace designs, two ring styles, three earring types, and a bracelet design, in silver, gold-plated, or rose gold-plated finishes.
Most importantly, DIY by MILKIES® uses MILKIES® patented technology to preserve full liquid breastmilk in resin without drying it, without mixing it with powders or clay-like bases, and without removing anything from it. The point is not to “transform” your milk into something else. The point is to keep it recognisably what it is, then lock it safely into a form that lasts.
- Privacy by design because your breastmilk stays with you from start to finish
- Control over timing so your nursing keepsake can be made when you feel ready
- Hands-on meaning because making the piece becomes part of the memory
- Professional-grade materials and guidance without needing a studio
- Choice of settings so the keepsake looks like jewellery not a craft project
The romance of a nursing keepsake is easy to understand. The realism matters, too. A piece you’ll actually wear needs stability, clarity, and a method that respects what breastmilk is: a complex liquid. That is where preservation technology stops being a marketing phrase and becomes the quiet engine of the whole experience.

What it means to preserve liquid breastmilk in resin
Most DIY options on the market ask you to dry breastmilk first, turn it into a powder, then mix it with another substance that behaves predictably in resin. It is an understandable workaround, but it changes the starting material. For mothers seeking a nursing keepsake that feels true, this can create a psychological distance: the milk becomes an ingredient rather than the point.
Preserving breastmilk in its liquid form is harder because liquids introduce variables: moisture content, stability, and the risk of separation or degradation over time. A reliable approach needs a preservation step that stabilises the milk before it is introduced to resin, as well as a resin system that cures in a way that supports clarity and long-term durability.
DIY by MILKIES® is designed around MILKIES® patented preservation technology for liquid breastmilk in resin. In practical terms, the kit guides you through measuring a precise amount of milk, mixing it with a preservation agent, and then combining that preserved milk with a carefully prepared resin emulsion. Timing and measurements matter because you are creating a controlled environment where the milk can be held in a stable, wearable form.
This is why the kit experience is structured. The workmat keeps steps in order. The step-by-step video guide reduces guesswork. The included tools (syringes, holders, mixing sticks) exist to protect accuracy and cleanliness, both of which are essential when your nursing keepsake is meant to last for years.
A quick note on safety and common sense: resin and preservation agents are chemicals, even when designed for consumer use. Wear the gloves provided, work in reasonable ventilation, avoid contact with eyes and skin, and keep the project away from children and pets while you work. The goal is a calm hour of focus, not multitasking through a milestone.
The technical promise is simple to describe and difficult to execute: keep the breastmilk pure, keep the process doable, and keep the final piece stable. When those three align, a nursing keepsake stops being a delicate idea and becomes a dependable object.
Proof that mothers want this done properly
MILKIES® has served over 100,000 customers across more than 50 countries, supported by thousands of 5-star reviews on platforms like Facebook and Google. DIY by MILKIES® brings that same seriousness to a nursing keepsake you can make at home.
The kitchen table workshop and the quiet pride of making
A nursing keepsake doesn’t need an audience, but it does deserve a moment. The best time to make it is not when you feel rushed, or when the house is loud, or when you’re doing it for the sake of ticking a box. It’s when you can give yourself a pocket of stillness. The box arrives in soft pink and blue, with compartments that make the whole thing feel less like a craft kit and more like a small, organised studio. You lay out the large workmat, and suddenly there is a map for your hands. Tools have a place. Steps have a rhythm. The instructions are comprehensive and readable, and the video guide is there when your mind wanders and you want someone to calmly bring you back. You pick your setting first. Some mothers choose a necklace because it sits close to the heart. Others choose a ring because hands did the work: the latching, the holding, the pumping, the constant washing up. Earrings can feel surprisingly right, too, because they are close to the face where your baby once studied you. Whatever you choose, the result is a nursing keepsake that meets you in daily life rather than living in a drawer. Then comes the part that feels more intimate than expected: measuring the milk. It is such a small amount, and yet it carries a whole era. There is a strange tenderness in being precise with something you once produced in abundance or fought hard to produce at all. You follow the steps, you mix, you time, you watch the liquid turn into something that can be set. And when you finally fill the setting, you see it: a milky, luminous centre that looks like a tiny held light. You set it aside to cure. You don’t hover. You just let it become what it is becoming. Later, when you lift the finished piece from its holder, the feeling is not only sentimentality. It is competence. You made a nursing keepsake with your own hands, and it looks like jewellery you would wear even if no one knew the story. That is the point. It is yours first.
- Choose your setting and prepare it so the surface is clean and stable
- Preserve a measured amount of breastmilk using the provided preservation system
- Prepare and time the resin mixture so it reaches the correct consistency
- Combine, fill the setting carefully, then let your nursing keepsake cure undisturbed
Choosing a nursing keepsake without settling for compromises
When you start looking, you’ll notice three main paths to a nursing keepsake. The first is the send-away service: you mail your milk, wait, and receive a finished piece. It can be beautiful, but it asks for trust in shipping, handling, timelines, and communication. For mothers who feel protective of their milk or anxious about loss, that emotional cost can outweigh the convenience.
The second path is the cheap DIY kit. These often rely on drying milk, mixing it with powders, or using craft-grade resin that isn’t designed for long-term clarity and stability. The process can feel vague, the results inconsistent, and the piece can end up looking like a “project” rather than fine jewellery. A nursing keepsake should not require you to accept uncertainty as part of the charm.
The third path is the professional-at-home middle ground: a kit designed with the seriousness of a brand that has already done this at scale. DIY by MILKIES® belongs here. It offers choice in jewellery styles and finishes, a structured process with a video guide, and a patented method that preserves liquid breastmilk in resin without drying or altering it. That combination matters if you want a nursing keepsake that feels private, reliable, and genuinely wearable.
There is also a softer comparison that rarely gets mentioned: what you do with the memory itself. Some keepsakes ask you to display the story. A wearable piece lets you carry it quietly. If your breastfeeding journey was complicated, hard-won, or simply yours, a nursing keepsake that doesn’t demand conversation can be the most respectful option.
A story you carry forward
Every mother has her own timeline, and every breastfeeding journey has its own texture. Some end with relief, some with grief, many with both. The point of a nursing keepsake is not to freeze you in the past. It is to honour the past so you can move without dragging it behind you. A piece of breastmilk jewelry made at home is small, but it is not trivial. It says the work was real. It says the tenderness was real. It says the long nights and the ordinary mornings count as a chapter worth marking. When you wear your nursing keepsake, you may think of the first latch, or the day it finally stopped hurting, or the feed that got you through a fever, or the quiet awe of your body doing what it did. Or you may simply feel grounded, as if the story has been placed somewhere safe. If you’re looking for a nursing keepsake that respects privacy, craft, and the emotional reality of motherhood, consider making one with your own hands, in your own time.
When you feel ready, set aside an hour, clear a small space, and let your nursing keepsake become something you can hold for years.
