Kasia Lew , mother of 2; extended breastfeeding & tandem nursing
From a mother’s moment to a lasting keepsake
MILKIES® began with Kasia Lew in 2013, after the birth of her first child, Adam. As she practiced extended breastfeeding, and later tandem nursing two children, she experienced the quiet, powerful bond that forms during this intimate season.
After months of research and development, Kasia launched MILKIES® on Mother’s Day 2016 from a home-based operation. It has grown into an international brand, serving 70,000+ mothers across 50+ countries who wanted a meaningful way to keep their story close.
DIY by MILKIES® was created by listening. Many mothers loved the idea of a breastmilk keepsake but felt hesitant about sending milk to a third party. With Kasia’s background in computer linguistics and multimedia, she built a complete DIY kit with step-by-step video guides that makes the process clear and approachable.
DIY by MILKIES® is the only kit that preserves liquid breastmilk in resin without altering its natural state. That commitment to authenticity and quality is central to Kasia’s mission: to help mothers keep what matters, beautifully, and truthfully.

A breastmilk keepsake that feels like your story
Breastfeeding is equal parts devotion and disappearance, a daily ritual that ends before you are ready to let it go. A breastmilk keepsake gives that time a shape you can hold, wear, and keep.
By Kasia Lew, Founder of MILKIES®
The last feed is rarely announced
If you are searching for a breastmilk keepsake, you probably already know the strange truth about breastfeeding endings. They do not always arrive with a ceremony. One day the feeding rhythm changes, the latch lasts a little less, and the chapter that once felt endless suddenly becomes finite.
The early months are noisy with guidance and opinion. Later, when it is time to stop or simply slow down, it can be oddly quiet. Friends move on. Partners are proud, relieved, confused. You may feel triumphant and bereft in the same breath, because you have been someone’s comfort, medicine, and home.
Objects help when language fails. We keep a hospital bracelet. A lock of hair. A photograph that proves we were there. But breastfeeding is harder to archive. It is intimate, largely unseen, and often reduced to logistics rather than remembered as a relationship.
A breastmilk keepsake is not about freezing time. It is about admitting it mattered. It gives weight to a season that can otherwise blur into night feeds, laundry cycles, and the soft ache of giving.
The question is not whether your breastfeeding story deserves a marker. It does. The question is how to choose one that feels safe, personal, and worthy of what you carried. That is where the right approach, and the right preservation method, becomes everything.
Why we crave proof of what we survived and what we loved
The emotional math of breastfeeding memories
Breastfeeding tends to be narrated in opposites. Natural, yet demanding. Tender, yet physically intense. Private, yet endlessly discussed. When it goes well, it can feel like a secret superpower. When it is hard, it can feel like a daily referendum on your adequacy. Either way, the experience is not neutral, so it makes sense that you want a breastmilk keepsake that carries the complexity, not just a cute symbol. Many mothers describe weaning as a quiet grief. There is the hormonal shift, yes, but also the identity shift. Your body stops being a place of instant comfort. Your baby becomes more independent. You become more visible to yourself again. A keepsake does not erase that transition, but it can make it feel recognized.
Why sending milk away can feel like too much
Classic breastmilk jewelry services often require mailing your milk to a studio. For some, that is perfect: you want the professional to handle everything, and you trust the process. For others, it raises immediate friction. What if the parcel is delayed? What if it leaks? What if you are not comfortable posting something so intimate to someone you have never met? This is where a breastmilk keepsake becomes about control as much as sentiment. Privacy matters. So does timing. You might want to make it during nap time, on your schedule, without explaining yourself to anyone. The modern keepsake market is catching up to that desire for autonomy.
The pressure to make it meaningful without making it performative
There is also a cultural trap around motherhood memorabilia. We are told to document everything, then judged for trying too hard. A breastmilk keepsake can feel vulnerable because it is unapologetically sentimental. Yet sentiment is not a flaw. It is a form of fidelity to your own life. The best keepsakes do not shout. They sit close to the skin and remind you, quietly, of what you did: the nights you stayed awake, the days you returned to work, the tandem feeds, the pumping sessions, the patience. Meaning does not need an audience. It needs a place to land.
When a keepsake becomes something you can actually make
Breastmilk jewelry is exactly what it sounds like: a piece of wearable jewelry that contains preserved breastmilk set into a resin “stone” or inlay. At its best, it is not novelty. It is craft, chemistry, and memory, with a result that looks refined enough to wear daily.
For years, the main route to a breastmilk keepsake was to ship milk to a studio and wait. That model works beautifully for many people, and MILKIES® built its reputation there by fulfilling over 100,000 orders for mothers across more than 50 countries. But the more breastmilk stories the team heard, the clearer one thing became: a significant group of mothers wanted a hands-on option, or simply did not want to send their milk anywhere.
DIY by MILKIES® was developed for exactly that gap. It is a do-it-yourself breastmilk jewelry kit created by the MILKIES® brand after years of professional keepsake work. The kit turns a kitchen table into a small, structured workshop, with a large work mat, tools, and a step-by-step video guide that functions like a calm instructor beside you.
Kasia Lew, the founder behind MILKIES®, is also a mother who practiced extended breastfeeding and tandem nursing. Her view of a breastmilk keepsake is not abstract. It is lived. With a background in computer linguistics and years running a multimedia agency, she approached the DIY experience the way she approached usability: fewer mysteries, more clarity, and a process that respects how little uninterrupted time new parents actually have.
Crucially, DIY by MILKIES® is designed around a specific promise: you can preserve full liquid breastmilk inside resin without drying it, without mixing it with powder, and without removing anything from it. That single technical decision changes the entire feel of the keepsake, because it aims to hold your milk in a form that stays closer to what it truly was.
- Privacy first because your breastmilk keepsake stays with you from start to finish
- Time flexibility because you can craft during a quiet hour at home
- Emotional ownership because making it becomes part of the memory
- Guided confidence because the step-by-step video reduces guesswork
- Design choice because the kit includes multiple jewelry styles and finishes
A breastmilk keepsake can be symbolic, but it also has to be stable. That stability depends on preservation. Many DIY kits on the market rely on drying the milk into powder or blending it with fillers before it ever meets resin. DIY by MILKIES® takes another route. To understand why that matters, it helps to look at what preservation is really doing, and why “liquid” is not just a marketing detail but a technical stance.

What preservation really means when you are casting breastmilk in resin
To make a breastmilk keepsake that lasts, you have to solve a practical problem: breastmilk is an organic liquid with water content, fats, and proteins. Resin, meanwhile, cures into a stable solid. If you introduce moisture incorrectly, you risk clouding, separation, brittleness, or long-term discoloration. That is why so many methods begin by drying the milk first.
Drying can work, but it changes the material. Powder-based approaches typically require dehydration, grinding, and then mixing the powder into resin or clay-like bases. You may still end up with a meaningful piece, but you are no longer preserving the milk as milk. You are preserving a transformed ingredient.
MILKIES® developed patented technology to preserve liquid breastmilk directly in resin. In DIY by MILKIES®, that technology is adapted for at-home use through a controlled, step-based workflow. The kit uses a preservation agent that is mixed with measured liquid milk, then incorporated into an emulsion with resin components at specific timings. The intention is simple: create a stable, uniform result without demanding that you dry, bake, or alter your milk beforehand.
That “pure liquid” approach matters for two reasons. First, it respects the original material emotionally. If you are making a breastmilk keepsake, you may want the comfort of knowing it truly contains your milk in its natural form. Second, it reduces user error by removing the most variable step in many DIY processes: home dehydration. Not every kitchen environment is the same, and not every drying method is reliable.
The DIY by MILKIES® kit also makes craft logistics less daunting. You are given a structured work mat, precisely sized syringes for measuring, and a workflow that depends on timing rather than intuition. Once the resin is mixed, you continue straight through casting, then let the piece cure undisturbed. The result is less like improvised crafting and more like following a well-designed laboratory recipe, translated into a home-friendly ritual.
Proof beyond pretty packaging
MILKIES® built this DIY system after fulfilling 100,000+ keepsake orders worldwide, earning a 5/5 star rating from 2,000+ reviews. DIY by MILKIES® carries that field-tested learning into a kit you can use at home, supported by teams in Europe and North America.
Your kitchen table becomes a small kind of studio
A breastmilk keepsake does not begin with the finished jewelry. It begins with the moment you decide your story deserves an artifact. For many mothers, the most tender part is that the making is quiet. There is no crowd. There may be dishes in the sink, a toy under the chair, and the low hum of a baby monitor. Still, you carve out an hour and call it yours. The box arrives in pink and blue, designed with compartments like a careful promise that nothing is missing. You lift the lid and see order: tools, blanks, small bottles, syringes that look more clinical than crafty, and a generous work mat that turns your surface into a mapped-out process. There is also a clear, readable instruction manual, and a step-by-step video guide that removes the fear of getting it wrong. You are not expected to be a jeweler. You are expected to be present. Choosing the jewelry feels surprisingly intimate. A necklace sits near the heart. A ring is a private glance every time your hand moves. Earrings are for the days you want the memory to meet the world. A bracelet is a quiet weight on the wrist. DIY by MILKIES® gives you multiple options, with finishes in silver, gold-plated, and rose gold-plated, so your breastmilk keepsake can match your actual life rather than an idealized version of it. Then the ritual begins. Gloves on. Workspace set. Milk measured. There is something almost calming about precision when so much of early motherhood is improvisation. You clean the setting carefully, as if you are making room for meaning. You follow the timing, stir with intent, watch the mixture turn milky-white, and notice how your attention narrows. The outside world recedes. When you finally fill the setting, you do it slowly. You are not merely pouring resin. You are setting a fragment of lived experience into a form that will outlast the fog of newborn months. It is strangely moving to see something once consumed, swallowed, and gone become visible and kept. You leave it to cure in a safe place, resisting the urge to check it every ten minutes. Waiting, again, becomes part of the story. Days later, when it is fully cured, you lift it from the holder and see it: your breastmilk keepsake, solid and luminous, not loud, not kitsch, simply there. A small proof that the time happened, and that you can carry it forward without having to relive every detail to justify it.
- Choose your setting and prepare a clean, level workspace
- Preserve a measured amount of liquid milk using the kit’s guided method
- Mix resin components and create the milky emulsion on a strict timeline
- Combine, cast into your jewelry, then let it cure undisturbed
What you are really choosing when you choose a keepsake method
Most breastmilk keepsake options fall into three lanes, and each appeals to a different kind of parent.
First, there are send-away services. The advantage is obvious: you do very little. Professionals handle the preservation and casting, and the finish can be beautifully polished. The tradeoff is emotional distance and logistics. You must package and post something intimate, trust transit, and wait. If your main need is control and privacy, that waiting can feel heavy.
Second, there are inexpensive DIY kits that rely on drying the milk or mixing it with powders and fillers. These can be accessible, but they often ask you to do the hardest part alone: transform a biological liquid into something resin can tolerate. Drying conditions, measurement accuracy, and material quality can vary widely. If your breastmilk keepsake is meant to last decades, inconsistency is not a small issue.
Third, there is the middle ground that DIY by MILKIES® aims to occupy: professional-grade preservation logic, but in your home, on your timeline, in your hands. The kit’s defining difference is that it preserves full liquid breastmilk in resin without the drying or powder step, supported by a structured workflow, tools, and a video guide. For mothers who want involvement without gambling on chemistry, that combination can feel like relief.
The best choice is the one that matches your temperament. If you want to outsource completely, a studio may be ideal. If you want the meaning to include making, and you want your breastmilk keepsake to stay with you from start to finish, a guided DIY approach is hard to beat.
Something small that tells the truth
At some point, breastfeeding becomes a story you tell yourself rather than an act you perform. The details fade first. The sensations fade next. What remains is the feeling: the closeness, the relentlessness, the tenderness, the strange pride of having given so much of your own body to another person. A breastmilk keepsake is not an attempt to live in the past. It is a way of making peace with time. It says, quietly, that your effort was real and that it deserves a physical witness. Whether your journey lasted weeks or years, whether it was easy or hard-won, the fact that you wanted to remember it is reason enough. If you have been waiting for the right moment to honor what you did, consider this permission. Make the hour. Clear the table. Follow the steps. Let the piece cure. Then wear your breastmilk keepsake the way you lived the chapter itself: close to the heart, and entirely your own.
When you are ready, start your breastmilk keepsake at home and let the making become part of what you remember.
