Designed by parents for parents, the Yoomi range has been developed to give parents complete flexibility on how and when they feed but also complete peace of mind that their baby is getting the maximum goodness from the precious milk …. Yoomi is ready anytime, perfect every time.
Yoomi was created by Farah and Jim, a Mum and Dad whose experiences of bottle feeding and warming for their son, who was born 6 weeks early, inspired them to look for a better solution. Farah was a lawyer working in London and Jim a former BMW design engineer and CEO of a product design company. The combination of Farah’s inspiration and Jim’s engineering skills together with support from industry experts, led to the creation of Yoomi, the world’s first self-warming baby feeding bottle… the only bottle that will warm your baby’s milk in 60 seconds, anytime and anywhere at the press of a button.
Hailed as one of the Top Ten British inventions of the decade, the Yoomi self-warming bottle does not use electricity or batteries, but instead uses unique patented technology designed, developed & manufactured by Yoomi in the UK. The Yoomi range has been extended to include a unique manual & electric breast pump and a Deep Clean electric steam steriliser, offering parents flexibility and choice whether they choose to breastfeed or use formula.
From the initial humble beginnings, Yoomi is now an international company with a manufacturing facility in the United Kingdom and operates in over 20 countries around the world.
Ready anytime. Perfect every time.
Just imagine - no plugs, no batteries, no flasks and no begging for hot water in cafes.
Our self-warming bottles are fully portable, warming your baby’s feed in just 60 seconds, anytime, anywhere. So they’re perfect when you’re out and about or for those middle of the night feeds.
A unique design.
Just press the orange button and the smart technology in the Yoomi warmer will warm the milk, straight from the fridge, in 60 seconds.
The cold milk is gently heated as it flows through the specially designed channels on the outside of the warmer. By the time the milk reaches the teat, it’s at perfect breastmilk temperature (32-34 deg C).
The smart warmer will stay warm for up to one hour. It uses the same gel as found in hand warmers, a non-toxic, food-grade concentrated salt solution (also used in ice cream). We've coloured it with blue food dye so it's easy to spot.
Sharing the joy. Preserving the goodness.
Breast pumps are a great way for you and your partner to share the joy of feeding your baby breastmilk - the perfect blend of vitamins, proteins, fats and antibodies to help baby grow and fight off viruses and bacterial infections.
But when it comes to warming your breastmilk, traditional heating methods can overheat the milk, reducing its nutritional value.
Our team of highly skilled engineers have developed a high-performance bottle that carefully controls the warming process, so the vital nutrients your baby needs never get damaged.
Safe and hygienic.
Traditional heating methods warm the entire bottle of milk, causing rapid bacterial growth. The longer your baby takes to feed, the longer the bacteria have to multiply, significantly reducing the milk’s nutritional and immunological value.
So we’ve designed the Yoomi warmer to only warm milk as your baby feeds. This means the milk remains cool until the sucking action draws it around the warmer. The warmed milk is immediately consumed, minimising bacterial growth and ensuring your baby receives the maximum goodness.
Tried and Tested.
The Yoomi self-warming system has been tried and tested by parents, midwives and health professionals all over the world.
Winners of over 30 awards in the UK, including ‘Best Bottle’, ‘Best Travel Invention’, ‘Best New Innovation’ and ‘Top Gear’, we’ve also won awards in the US, France, Japan and Sweden.
In a ‘breast to bottle’ independent parent review by Mother & Baby magazine, Yoomi was awarded a 5/5 ‘Best Buy’ beating leading brands as the ‘Best bottle for breastfed babies’.
How does the Yoomi warmer work?
The warmer works in the same way as the gel hand-warming packs that warm up when you click a metal disc inside – when you press the orange button on the yoomi warmer, you’re effectively clicking the metal disc and it’s the phase change from liquid to solid inside the warmer that creates the instant warmth.
The cold feed is gently warmed as it flows around the specially designed channels on the outside of the warmer. By the time the feed reaches the teat, it is at natural breast milk temperature (32-34 deg C). The warmer has been carefully designed to stay warm for up to one hour.
You then need to recharge the warmer between each use. You need to take the warmer back to its liquid state inside, ready to use again.
Are the contents of the warmer safe?
Yes, the contents of the warmer are safe. The warmer contains the same gel as used in commonly available hand warmer packs.
The gel is a non-toxic, concentrated salt solution (It is used as an additive in ice cream). Just to be extra safe, we have added a food grade colourant so that any leaks are visible, and Bitrex®, a safe but bitter substance that will ensure that in the very unlikely event of a leak, baby will not swallow any of the solution.
Can Yoomi overheat my baby's feed?
No, it cannot. Our engineers have designed the yoomi system so that it is impossible for baby's feed to be warmed above a safe, maximum temperature (when used as instructed). This means that there is no possibility of baby being exposed to unsafe temperatures from either the bottle or the warmer.
How do I know when my warmer is ready to use (fully recharged)?
Your warmer is ready to use when:
1) it has been allowed to cool after recharge (75 minutes at room temperature or 20 minutes in cold water),
2) it rattles when you gently shake it (when warmer is cool) and 3) the button is orange.
How do I know that the warmer has begun to warm up after I have pressed the orange button?
After pressing the orange button firmly, please WAIT 30 seconds for the orange button to start fading. A blue button indicates that the warmer is warming up. Also, after 2-3 seconds the warmer will no longer rattle when gently shaken.
How do I know when I need to recharge the warmer?
Your warmer needs to be recharged if there is no rattle when you shake it. This is because it is still solid inside after its last use. To recharge it you need to ‘melt’ the contents to take it back to a liquid so that it’s ready to go again.
A new warmer will always need charging before its first use.
My warmer won’t activate - the rattle is there and sounds like a ball in liquid.
If your warmer has charged correctly and you have a rattle that sounds like a ball in liquid, yet your warmer will not activate, the activator inside the button has become dislodged. You can reset your warmer easily with the following steps;
1. Put your warmer in the deep freeze (under the peas etc!) for 90 minutes but no longer.
2. After 90 minutes, take the warmer out of the freezer and shake it. The rattle should still be there although it may sound a bit fainter - as if the contents inside have frozen.
3. Press the button - it will be much harder to physically press than a warmer that has not been frozen - please don't be afraid and press hard. It may take a few repeated prods with slightly more force.
4. It should activate as normal - you'll know if it has activated as the rattle will disappear within 2-3 seconds.
5. Although you can't use this warmer for a feed, it will completely reset it and so you won't ever have to freeze it again.
When should I replace my warmer?
Replace the warmer at the first sign of damage or if blue dye is visible.
Replace your warmer after 300 uses
Replace your warmer if the button no longer turns orange at all after being cooled to room temperature
There is a tick box table within the instructions to help you keep track of your usage.
How can I sterilise and recharge the Yoomi warmer?
The warmer should be sterilised and recharged before each use. There are 3 options to recharge the warmer; in a microwave using the Yoomi pod, in a pan of boiling water or in an electric steam steriliser. Boiling and steaming also sterilises but when using the pod, you need to then sterilise the warmer either in a (non-microwave) steam steriliser, in boiling water or by using a cold water sterilisation solution.
How soon after recharge can I use it again?
Please be careful when handling the warmer as it will be very hot immediately after the completion of the sterilisation cycle or after having been in a pan of boiling water.
Please let the warmer cool for 75 minutes (at room temperature) or for 20 minutes (in a bowl of cold water). If you use water, the warmer will no longer be sterile (fine for babies over 1 year). Try using a cold water sterilisation solution to speed up the cooling and also keep it sterile for longer.
How long does the warmer stay charged?
In general, the warmer will remain recharged almost indefinitely and will be ready for use when you press the orange button - so it’s up to you how often you would like to use your warmer. Very occasionally, it is possible that the warmer can be inadvertently activated if it is bumped hard, so keep it protected and remember that it will need re-sterilising if left for long periods.
my warmer does not recharge or will not stay recharged
It may not have been charged for a sufficient period of time, try recharging it again - follow the recharge tips on the instructions. Very occasionally it is possible that the warmer can be activated by being bumped hard. Please handle the warmer with care.
I have pressed the button when the warmer was hot, is this a problem?
Yes, pressing the button when the warmer is hot deactivates the warmer and prevents the warmer from working. Unfortunately, the warmer will need to be replaced if this occurs.
My warmer is charged, but no longer sterile – how can I sterilise it? Do I have to recharge it again?
Once your warmer is charged, it stays charged indefinitely, however it will need re-sterilising if you don’t use it straight away. You can either put it on a regular sterilisation cycle (not in a microwave) but remember you’ll have to let it cool. The perfect way to re-sterilise your warmers is to use a cold-water sterilisation solution such as Milton. This way you can sterilise the warmers and use them straight away.
Does Yoomi fit in conventional sterilisers from other manufacturers and which do you recommend to charge the Yoomi warmers?
All Yoomi parts fit in conventional sterilisers from other manufacturers. It is best to sterilise the Yoomi bottle separately from the Yoomi warmer as the warmer requires additional time in the steriliser. The following electric steam sterilisers are compatible with Yoomi warmers:
Does the warmer adversely affect the nutrients of my baby's feed?
No, it does not. The Yoomi warmer has been specially designed to gently warm baby's feed to breast milk temperature. This gentle process ensures that baby receives the maximum nutrition from the feed unlike other heating methods such as a microwave which can damage nutrients.
