We Tried to Break the 3 AM Bottle Curse — Meet Nuby RapidCool™
If you’ve ever stood in the kitchen in the middle of the night, bouncing a hungry baby on one hip while frantically cooling a bottle under the tap like a sleep-deprived barista… this one’s for you. Nuby’s RapidCool™—a tiny, travel-friendly gadget that cools freshly boiled water + formula to feeding temp in just a couple of minutes—has landed in Australia (after flying off shelves in the UK), and it’s aiming straight at the pain points of night feeds, daycare drop-offs and weekends away.
Below: what it is, how it works, where it shines (and where it doesn’t), plus real-world scenarios to help you decide if it’s worth the space in your nappy bag.
What is RapidCool™?

Think of RapidCool as a compact, insulated bottle-cooling pod. You mix the feed with freshly boiled water (per global safety guidance for powdered infant formula), seal, and the unit rapidly brings it down to a comfortable feeding temperature—safely and consistently—without the guesswork. No running taps, no juggling ice baths, no microwave roulette.
- RRP: $69.99
- Where to buy: Baby Bunting and Ramsay Pharmacy
- Best for: Formula-feeding families who want a faster, safer, on-the-go route from kettle to cuddle
Safety note: Health authorities advise preparing powdered formula with water that has been boiled and cooled to no less than 70 °C, then bringing it down to a safe feeding temperature. RapidCool’s whole job is to make that final “cool it quickly” step fast and predictable. Always follow your formula tin instructions and test the milk on your wrist before feeding.
Why parents are buzzing about it
1) It attacks the real bottleneck (pun intended)
Boiling water is easy. Waiting for it to cool is not—especially at 3 AM or while your toddler practices parkour off the couch. RapidCool shortens that “cool-down limbo” to a couple of minutes, so the feed is ready about as fast as you can settle in to the feeding chair.
2) It ditches the guesswork
No more “hmm… lukewarm? too warm? try again?” loops. You follow the simple steps, and the unit handles the cooling. You finish by testing a few drops on your wrist like always.
3) It’s nappy-bag small
Because it’s compact and self-contained, it earns its spot next to wipes and snacks. Huge win for travel, daycare hand-offs, or feeds anywhere that kettles and cold taps are in short supply (sports sidelines, grandparents’ house, the boot of your car).
4) It’s budget-friendly
At $69.99, it’s less than many benchtop formula gadgets and doesn’t lock you into a bulky appliance. One device, many situations.
How it works (in plain English)
- Boil fresh water (kettle or stove).
- Measure & mix your powdered formula with the hot water inside RapidCool, following the scoop-and-water ratios on your formula tin.
- Seal, shake, wait a short beat. The unit does the rapid cooling.
- Test a few drops on your wrist, then pour into your baby’s bottle and feed.
That’s the workflow. It’s designed to support the safety step (hot enough to neutralise bacteria) and the sanity step (cool enough to feed soon).
Real-life use cases (where RapidCool shines)

Night feeds at home
Prep in the kitchen, head back to the nursery with a ready-to-pour feed in a couple of minutes—and skip the tap-cooling routine entirely. Pair with a dim night-light and your future self will thank you.
Out and about
Take a small thermos of freshly boiled water, your RapidCool, a clean bottle and formula powder. You can prep safely at the café table while your baby conducts a biscuit-crumb science experiment.
Daycare drop-offs & grandparents
Hand over a simple, repeatable process (no fiddly machines or timing anxiety). For carers who want safety + speed without owning extra equipment, this is a gift.
Travel days
Hotel rooms, holiday houses, the great outdoors—RapidCool helps you stick to your formula’s safety instructions without camping out by the bathroom sink.
Pros & cons (because no product is perfect)
The big wins
- Fast & predictable: Dramatically cuts the cool-down delay.
- Portable: Toss it in the nappy bag; no power outlet needed during cooling.
- Simple workflow: Mix hot, seal, cool, test, pour.
- Great price point: Accessible compared with larger appliances.
- Less water waste: No more running the tap to cool bottles.
Things to keep in mind
- One-at-a-time tool: If you’re batch-prepping multiple feeds back-to-back, you’ll repeat the cycle for each feed (still quicker than waiting for bottles to cool on the bench).
- Cleaning matters: Like any feeding gear, good hygiene is non-negotiable. Follow Nuby’s instructions for cleaning/sterilising between uses.
- It complements your routine; doesn’t replace judgment: Always test temp and follow your formula’s directions.
The “but how safe is it?” conversation (let’s have it)
Powdered infant formula isn’t sterile. Health guidance recommends mixing with boiled water no cooler than 70 °C, then cooling to a safe feeding temperature. Parents have long hacked that process with running taps or ice baths—which can be inconsistent and time-consuming. RapidCool streamlines the cooling step so you can do the safe thing fast, at home or on the go.
As always:
- Wash hands and surfaces before preparing feeds.
- Use clean, sterilised feeding equipment.
- Follow the scoop-to-water ratios and directions on your formula tin.
- Test the final milk temperature on your wrist before feeding.
- Discard any unfinished feed within the time window your formula brand recommends.
If you’re unsure about prep, check in with your child and family health nurse or GP.
The parent-proof checklist
- Simple steps: You shouldn’t need a manual at 2 AM. RapidCool keeps it basic.
- Works with your bottle brand: You mix in RapidCool, then pour into your usual bottle.
- Tiny footprint: No new appliance to explain to nan.
- Price you can justify: $69.99 is “shower-gift” territory.
- Retailers you know: Baby Bunting, Ramsay Pharmacy.
Who will love it (and who might not)

Perfect for:
- Formula-feeding families who want safer, faster, repeatable prep at home and on the go.
- Parents with older kids (busy afternoons) or frequent travellers.
- Daycare/grandparent households that need a fool-proof method without a machine setup.
Maybe not for:
- Families exclusively breastfeeding (obviously!).
- Parents who already have a benchtop system they love and never prep outside the kitchen.
Tips to get the most out of RapidCool
- Build your “go kit”: Pre-measure formula in a dispenser, pack RapidCool, a clean bottle, and a small thermos of freshly boiled water.
- Make cleaning automatic: Rinse straight after use; follow Nuby’s cleaning/sterilising guidance daily.
- Keep spares smart: A second clean bottle on hand means you can pour and feed while RapidCool gets a quick clean.
- Night-feed station: Kettle, RapidCool, formula, bottle, burp cloth. Done.
FAQs (the ones everyone asks)
Can I use lukewarm tap water?
No. Health guidance recommends mixing powdered formula with water that has been boiled and cooled to at least 70 °C before you cool it for feeding. RapidCool is the “cool it quickly” step—not a substitute for boiling.
Does it work with any formula brand?
Yes—follow the measurements and directions on your specific tin.
Do I feed straight from RapidCool?
You pour the cooled feed into your baby’s bottle to feed, and always wrist-test the temp first.
How many feeds in a row can I make?
One at a time. If you’re doing back-to-back, clean between uses as per the instructions.
The verdict
Nuby RapidCool™ is one of those rare parenting gadgets that solves a real-world problem without overcomplicating your life. It respects the safety step (mix with freshly boiled water), then slashes the wait to a calm, feed-ready temperature—whether you’re bleary-eyed at midnight or balancing a pram, a coffee and your last shred of patience at the park.
At $69.99, it’s an easy recommendation for formula-feeding families who value speed, safety and portability. Will it make every feed dreamy? No product can promise that. But it will turn the most frustrating part of formula prep into a short, repeatable ritual—and on the parenting battlefield, that’s a genuine win.
