Kasia Lew , Mother of 2, practiced extended breastfeeding & tandem nursing
From Mother’s Heart to Forever Keepsakes
Kasia Lew’s journey began in 2013 with the birth of her first child, Adam. As a mother who practiced extended breastfeeding, and later tandem nursing two children, she deeply understood the bond created during this intimate season and the desire to hold onto it.
After months of research and development, MILKIES® launched 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.
DIY by MILKIES® was created by listening closely to customers. Many mothers felt hesitant about sending breastmilk to a third party. With Kasia’s background in computer linguistics and multimedia, she helped design a complete DIY kit with step-by-step video guides that feels calm, clear, and empowering.
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, preserved as it was.

A breastmilk keepsake that feels like you, not a souvenir
Breastfeeding is intimate, exhausting, ordinary, miraculous. If you want to keep a piece of it without mailing your milk away, the new generation of at-home preservation kits makes the memory tangible.
By Kasia Lew, Founder of MILKIES®
The moment the last feed becomes a memory
There is a particular quiet that arrives after the final latch. No announcement. No music. Just the soft click of routine ending. One day you realize you are no longer counting feeds, no longer packing nursing bras “just in case,” no longer feeling that small, private tug that says you are still someone’s entire world at 3 a.m. And suddenly you want proof it happened at all.
For many parents, the instinct is practical at first. A freezer bag with dates. A photo you never quite print. A onesie sealed in a box that will smell faintly of detergent, not of that season of your life. But breastmilk is different. It is time made visible. It is labor and love you cannot outsource, and a bond that is hard to describe to anyone who did not live inside it.
That is why a breastmilk keepsake is not a trend so much as a response to a gap. We are good at documenting babies. We are less fluent at honoring what mothers did to get them here. Breastfeeding is often narrated through milestones and opinions rather than through the everyday devotion it actually is.
A breastmilk keepsake can be a way of saying, without apology, this mattered. Not because you need to prove anything to anyone, but because you deserve a marker of your own endurance and tenderness. It can be a small object that holds a big chapter, and it can be made in a way that respects your privacy and your pace.
If you have been searching for something that feels personal rather than performative, you are not alone. The good news is that the options have matured. Today’s best approaches focus on preserving breastmilk in its natural state and turning it into jewelry that looks like fine design, not craft-store resin.
Why we want to hold on to something that was meant to disappear
Breastfeeding ends but the body remembers
Even when weaning is planned, it can arrive with an emotional aftertaste. Hormones shift, routines reorganize, and the body that once felt like a constant source of comfort can suddenly feel oddly quiet. People talk about the baby’s transition, but many mothers experience weaning as a private grief. A breastmilk keepsake becomes a gentle counterweight to that feeling. It is not nostalgia for its own sake. It is a way of acknowledging that the relationship changed, and that change deserves a ritual.
The pressure to choose the right kind of meaning
If you have ever been asked whether you want to “do something” with your milk, you already know how quickly meaning can become a performance. Some keepsakes feel overly sentimental. Others feel clinical. What many parents want is simpler and harder at the same time: an object that is discreet, stylish, and emotionally specific. A breastmilk keepsake that looks like jewelry you would wear even if nobody knew what it contained can be deeply comforting, precisely because it keeps the story yours.
Privacy and trust are part of the decision
The most common hesitation is not about the idea but about the logistics. Mailing breastmilk to a third party can feel exposing. There are practical worries about shipping, temperature, and loss, but also a basic question: do I want strangers handling something that came from my body? That question does not make you anxious; it makes you sensible. The rise of at-home methods is largely a response to this. A breastmilk keepsake that you create yourself can offer the reassurance of control, while still meeting a professional standard of preservation.
The keepsake that becomes a piece of jewelry you actually wear
A breastmilk keepsake can take many forms, but jewelry has a unique advantage. It is close to the body, it is portable, and it does not require you to open a box to feel the memory. The best pieces do not scream for attention. They sit on your neck, your wrist, your finger, and they whisper. You know what they mean, and that is enough.
DIY by MILKIES® was created for mothers who want that intimacy without the complicated part of sending their milk away. After MILKIES® had already completed over 100,000 orders in keepsake jewelry, a pattern became impossible to ignore: a significant group of customers loved the idea but could not get comfortable with shipping breastmilk to anyone, no matter how reputable. DIY by MILKIES® is the answer to that hesitation, designed as a true at-home workshop rather than a “best effort” craft kit.
The kit arrives in a beautifully designed pink and blue box with compartments that make the process feel organized from the start, not chaotic. Inside you’ll find a large workmat, tools, and an instruction manual that is extensive and clear. There is also a step-by-step video guide that walks you through the process in real time, so you’re never trying to interpret vague diagrams while resin cures on the table.
You choose the jewelry style that suits you. The range is broad enough to feel like a collection, not an afterthought: four necklace designs, two ring styles, three earring types, and one bracelet design. Each piece is available in silver, gold-plated, and rose gold-plated finishes, so your breastmilk keepsake can match what you already wear.
What matters most, though, is what happens under the surface. DIY by MILKIES® uses MILKIES® patented preservation technology to stabilize breastmilk and set it in resin while keeping it in its liquid form. No drying. No powder additives. No “milk dust” mixed into a base. The keepsake is made from the real thing, preserved as itself.
- Keep your breastmilk keepsake private by making it at home on your own timeline
- Create a professional-looking piece with a guided process, tools, and a dedicated workmat
- Preserve breastmilk in its pure liquid form without drying, powders, or clay-style fillers
- Choose jewelry that fits your style, with multiple designs and three metal finishes
- Turn the act of preservation into a personal ritual rather than an outsourced service
The emotional pull of a breastmilk keepsake is obvious, but longevity depends on method. Breastmilk is a living, changeable substance; resin is permanent only when the chemistry is right. To understand why some keepsakes yellow, crack, or lose their clarity over time, you have to look at what most kits ask you to do to the milk first. The difference between altering milk and preserving it is the difference between an imitation and an heirloom.

What preservation really means when the ingredient is breastmilk
Most DIY options on the market begin by asking you to dry your breastmilk. Sometimes it is air-dried, sometimes dehydrated, sometimes “turned into powder” through methods that vary wildly in consistency. After that, the powdered milk is mixed with resin or clay-like bases. The resulting look can be pretty, but the process changes the substance fundamentally. It is no longer breastmilk as it existed in your breastfeeding life; it is a derivative.
DIY by MILKIES® approaches the problem from the opposite direction. Instead of drying breastmilk and hoping a mixture behaves, it uses a preservation method designed for liquid milk. The kit stabilizes a measured amount of breastmilk using a dedicated preservation agent, then integrates that preserved liquid into high-quality resin as part of a timed, controlled process. Because the milk stays liquid through preservation, you avoid the common pitfalls of uneven powders, clumping, and unpredictable color shifts.
This matters for the final look, but also for confidence. A breastmilk keepsake is not a weekend craft you casually remake if you don’t love it. The kit’s design acknowledges that emotional reality by making precision easy: syringes for measurement, a clear sequence, and a video guide that keeps you on track. You’ll mix preservation agent with a defined amount of milk, prepare resin with a hardener and additive, and then marry the two at the right moment so the final casting cures with clarity and stability.
There is also a quiet ethical dimension to the “pure liquid” promise. Many mothers do not want their breastmilk turned into a symbolic ingredient, diluted into a base that could be anything. Preserving the milk without removing anything from it respects the original material. It treats breastmilk not as a craft pigment but as a personal artifact.
Behind this kit is a company that has already built its reputation in keepsake jewelry at scale. MILKIES® has served over 100,000 customers across more than 50 countries, with a 5/5 star rating from over 2,000 reviews on platforms including Facebook and Google. That history is not a guarantee of your personal outcome, but it is evidence that the preservation problem has been confronted repeatedly, refined, and supported by real customer experience.
Proof you can feel in the details
DIY by MILKIES® stands on the foundation of MILKIES® experience with over 100,000 keepsakes delivered worldwide and thousands of 5-star reviews. The difference shows up in the kit’s measured workflow, support, and patented liquid preservation approach.
Your kitchen table becomes a small studio
A breastmilk keepsake is often imagined as a finished object, photographed on a wrist or resting against a collarbone. But the making of it can be just as meaningful, especially when it happens at home. You clear a space, not because you need a pristine laboratory, but because you want a moment that is yours. The workmat goes down like a promise that this will be orderly. The box opens in compartments, each piece in its place, and for once the process of mothering is not improvisation. You set a timer. You put on gloves. You watch the video guide once all the way through, then again with your hands moving along with it. There is comfort in being told exactly what to do, step by step, when so much of early parenthood is guesswork. The milk you measure is small in volume and huge in meaning. It is strange, in the best way, to see it treated with the seriousness it deserves. The preservation step feels like science and ritual at once. You connect syringes, mix for a precise minute, check for bubbles, measure again until it is exact. In another life, this level of precision might have felt fussy. Here it feels like respect. You are not rushing; you are paying attention. When resin enters the story, time becomes a real ingredient. You mix, you stir, you watch the liquid turn into a milky-white emulsion, and you realize why interruptions are discouraged. This is one of the rare tasks in motherhood that asks you to finish what you started, uninterrupted, and it can feel oddly restorative. Finally, you fill the setting. If it is a pendant, the pour is slow and close, as if you are trying not to startle the surface. If it is a ring or a small earring, you build it drop by drop. You correct a spill with a cotton swab and degreaser, clean edges until they are sharp again, and place the piece on a level surface to cure. Then you wait. Twenty-four hours becomes a quiet kind of suspense, the way waiting for a pregnancy test once did. When you remove the cured piece from its holder, you are holding a breastmilk keepsake that is no longer fragile. It is set. It is wearable. It is a chapter of your life translated into something you can touch whenever you need to remember what you carried.
- Set up your workmat, choose your setting, and prepare a calm hour of uninterrupted time
- Preserve a measured amount of breastmilk using the kit’s syringe-based method
- Mix resin components precisely, then create the milky emulsion before your working time runs out
- Combine preserved milk with the resin mixture, fill your jewelry setting, and let it cure fully
Choosing between send away services and DIY kits
A breastmilk keepsake sits at the intersection of emotion and materials science, which is why the market splits into two extremes. On one end are send-away services: you ship your milk, professionals do the work, and you receive a finished piece. For some, that is ideal. For others, it introduces friction that is hard to ignore: privacy concerns, shipping anxiety, and the uneasy feeling of handing over something deeply personal.
On the other end are low-cost DIY kits that treat breastmilk like a colorant. Many require drying the milk, mixing powders, or using generic resin without a preservation method designed for breastmilk. The results can vary, and variability is the enemy of heirlooms. When a keepsake fails, it rarely fails loudly. It clouds, it yellows, it loses the look you wanted, and your trust goes with it.
DIY by MILKIES® positions itself in a middle category that has been missing: professional-grade preservation at home. The kit borrows from the discipline of a jewelry studio, measured tools, clear sequence, and guided instruction, while keeping the process in your hands. You can work privately, at your own pace, with localized support from teams across regions including Germany, the UK, the USA, and Canada, backed by production facilities in Poland.
The best choice depends on what you value most. If your primary need is to avoid handling resin, a send-away service may still appeal. But if your primary need is control, privacy, and the satisfaction of making something real from your own story, an at-home breastmilk keepsake kit designed around liquid preservation can feel like the most honest option.
A story you can wear on ordinary days
There will be a day when you stop thinking about breastfeeding altogether. Not because it was insignificant, but because life expands again. The baby becomes a child with opinions. You become more than a schedule. And yet, you may still want one small object that says, quietly, I did that. A breastmilk keepsake is not about freezing time. It is about giving yourself a dignified marker of a season that asked a lot of you. When that marker is a piece of jewelry made from your milk in its pure form, created by your own hands at your own table, it carries a particular kind of truth. If you feel that pull, honor it. Choose a method that respects the material, and a process that respects you.
When you’re ready, start your breastmilk keepsake at home and let the memory take a shape you’ll actually want to keep close.
