If you could grant yourself one extra magical power as a mom, which would you choose? Not feeling tired? Always knowing exactly what your child needs? Or being able to whip up a good meal, bottle, homemade puree, or dish at any moment? If that last wish sounds like you, just know that at Élhée we’ve discovered an appliance that's not magical, but almost, and totally compatible with our bibRonds: the bottle prep machine.
What is a bottle prep machine used for?
Imagine a coffee maker, but for infant formula. Convenient and fast, it would be used to prepare baby bottles instead of your hot drinks. In reality, this handy little kitchen appliance already exists. Just a bit bigger than a bottle warmer, it's mainly designed to come to our rescue in emergencies.
The idea behind this invention is a machine that's able to take over for parents by preparing milk meals for baby, handling the amount of formula, the evenness of the drink, and its temperature. And it does all this in under 2 minutes for most of the models on the market.
How does an automatic bottle prep machine work?
Gather the infant formula, a bottle of mineral water suited for newborns, the bottle, and a teat fitted correctly to its screw ring. Whether the formula goes into the bottle or straight into the machine, the bottle prep machine heats the water or preparation to around 98.6 °F— the temperature of breast milk — so baby can drink right away with no risk of being burned.
In short, once your machine is set, place the open bottle in the dedicated spot under the spout and press the button. The time it takes for a kiss, and you’re done.
5 advantages for baby meals
- Fast, it prepares the bottle in just a few dozen seconds
- Hygienic, it reduces the need to handle formula, often has a full self-cleaning mode and, depending on the model, a sterilizing compartment for bottles
- Efficient, it heats the water or milk preparation to 98.6 °F, the ideal temperature, in just a few seconds
- No waste, you no longer risk spilling the dose of formula, adding too much, or throwing away a failed bottle
- Multi-purpose, the bottle prep machine can also be used to heat up baby food containers during solid food introduction

How to choose a bottle prep machine without making a mistake
Measuring, mixing, dispensing, heating, and even sterilizing or storing, bottle prep machines offer several advantages. Élhée helps you sort through them to choose the features that are truly essential for you.
Basic or multi-function?
At its most basic, a bottle prep machine is used to bring water to the right temperature and provide a consistent mix with no wait. Milky Now by Babymoov, for instance, claims to prep a bottle in under 40 seconds.
Multi-function machines can measure out both the formula and water from different containers, but also sterilize the bottle or heat up baby meals when you start introducing baby foods. That's especially true of the Bib’Expresso® by Béaba, which offers a water bath function also designed for travel usage.
A wide enough range of measurements
Whether your baby is a big eater or just nibbles, make sure to pick a machine that offers enough measurement options. Some only offer common bottle sizes (5, 8, and 11 oz), while others are more flexible, offering amounts starting at just 2 oz with Babymoov's Milky Now and even 1 oz for BabyBrezza. This is also handy for small meal supplements or in-between age stages.
Extra features?
A bottle holder might be built in, as well as a water filter, which is perfect for giving extra comfort to sensitive tummies. This feature, for example, is found on the Perfect Prep Closer Tommee Tippee, which can filter tap water and prep several bottles in advance throughout the day.
Some models can even be connected to a smartphone or tablet to start prepping remotely and keep track of baby’s feeding schedule easily, including growth charts.
Consider which features are important for you and your child in the coming weeks and months, especially since some can raise the price beyond your budget.
Equipped with two reservoirs, one for powdered formula and one for water, the Formula Pro by BabyBrezza is, for new parents, the Rolls Royce of these machines. Once it’s filled, you don’t have to do anything else—it measures out both formula and water and takes care of everything in under 10 seconds.
Maximum compatibility
Over the weeks and months, you’ll probably use different bottles of assorted sizes and capacities, as well as other small containers to prep and sometimes carry baby meals. Making sure your machine is compatible is important if you want to keep using it for a long time, maybe even until baby eats regular meals with you.
BibRONDS Élhée: compatible with all instant prep machines
With its round shape, soft curves, and motherly flexibility, the bibRond by Élhée doesn’t look like any other bottle. Maybe that’s what made you fall for it and buy it? Or maybe it’s the colors—both delicate and trendy—perfect for coordinating with a baby shower gift? Most of all, it’s the healthy, safe medical-grade silicone that truly won you over.
And if we gave you one more reason to grab our lovely bibRond Élhée? Now’s the time to discover that our bibRonds in 5, 8, and now 11 oz, are all perfectly compatible with bottle prep machines on the market!
Forget about the bottle warmer that’s too small, too slow, overheats, doesn’t mix the formula, and doesn’t sterilize the bottle. Say hello to a prep machine you can keep front and center on your kitchen counter, right next to your collection of round bottles!
And if a bottle warmer is a must-have for you (you’re absolutely right!), check out the portable, rechargeable bottle warmer and its up to 12-hour autonomy! Rechargeable via USB-C, it screws directly onto Élhée bottles to warm water or milk (breast or formula) in just 5 minutes flat. Want to give it a try?

BibRond Élhée: combining convenience and safety
With its line of revolutionary bibRonds, Elhée focused on baby safety. That’s why medical-grade silicone and a unique closure system ensure a healthy preparation with every meal. For your peace of mind—and because we know a newborn brings a thousand worries—the formula only comes into contact with the carefully selected silicone for both the body and nipple of the bibRond, which is free from chemical substances like Bisphenol A and S.
