Your new must-have for stress-free formula feeding. Designed specifically for parents who want convenience, confidence, and peace of mind, this premium smart thermos takes the hassle out of both on-the-go and middle-of-the-night feeds.

This Bottle keeps 750mls of sterilised water warm for up to 12-24 hours (and maintains cold or warm temperatures for 12–24 hours), so you can prep bottles whenever your baby needs them — no rushing, no reheating, no waiting.

Love Lil Moo

Amazing for travel!! Perfect for our family road trips, don't have to muck around with warming or finding boiling water then adding a bit of cold water etc etc, easy to know exactly when its ready and keeps the water clean as don't need to test it before hand!

Lily

Really considered if I needed this.. but I'm so glad I got this. I can go out for the day and have no worries about trying to find somewhere to warm his bottle up as it stays warm. Also over night it's perfect.
Definitely something I would tell other mothers to get

Bonnie E

I love you can use this for road trips and not have to worry about the water being to hot or to cold, the temperature being perfect for baby is amazing and gives them that comfort they need wherever you are. I wish I had this with my first baby! Such a life saver!

Eyisha

This was an absolute lifesaver when traveling!! Our hotel room did not have a microwave so we just filled this up with hot water each night before bed, then could instantly make bottles throughout the night in the room, and stayed warm all the next day too. Amazing!!!

Shannon

Making feeding time easy! Having the water heated and kept at the perfect temperature prevents me from having to go downstairs to the kitchen during night time feeding. Resulting in my baby staying sleepy and not requiring any or as much effort to be soothed back to sleep. On the go water for outings, making life easy especially since we prefer warm milk to help with our babies sensitive digestion.

FAQ's

What actually is the Smart Formula Feeding Thermos?

It's not a bottle warmer - it's instant. It doesn't heat anything. It holds 750ml of pre-boiled, sterilised water at a safe, consistent feeding temperature for up to 12–24 hours, with an inbuilt thermometer in the lid so you can check the temperature with a swipe of your finger. No power, no cords, no waiting. Just pour, add formula, feed.

Why is it so handy?

Because it takes the two hardest parts of formula feeding — timing and temperature — out of the equation. Keep it on your bedside table and a 2am feed takes 30 seconds instead of a trip to the kitchen. Take it to the park, the car, the airport, and you've got warm sterilised water ready to go without hunting for a café or a microwave. It's the closest thing to the speed and simplicity of breastfeeding.

Why can't I just use a kettle?

Kettles boil water beautifully. They just don't solve the problem. With a kettle you still have to wait for it to boil, wait for it to cool, then guess whether it's the right temperature — usually with a hungry, crying baby. And a kettle can't come with you to the park. The thermos removes the waiting and the guesswork entirely.

Why not just use a normal insulated thermos?

A regular thermos will keep water hot — but "hot" isn't what you need. You need a specific, safe feeding temperature, and you need to know it's that temperature without dipping a finger in or pouring a test bottle. Our thermos has a stainless steel body with a copper layer for a longer, more stable temperature hold, plus an inbuilt smart thermometer and touch display so you know exactly where you're at. A standard thermos leaves you guessing; this one tells you.

How does it work?
  1. Fill it with sterile, hot water — slightly warmer than your baby's ideal temperature if you plan to feed hours later.
  2. Before opening, flip the thermos upside down so the water touches the lid.
  3. Swipe your finger across the top of the lid to read the temperature.
  4. Pour into your baby's bottle, add formula, mix, feed.

The whole thing takes about 30 seconds.

Do I have to charge it?

No. The touch display runs on a long-lasting battery, so there's nothing to plug in, nothing to charge, and no risk of it dying on you halfway through a trip. Grab it and go.

Can I put formula or breastmilk in it?

No — the thermos is designed for water only. When your baby's ready to feed, pour the water from the thermos into their bottle and add the formula then. Breastmilk shouldn't be held at a warm temperature for long periods, and made-up formula shouldn't sit either, so keeping the thermos to water is what keeps every feed safe and fresh.

Temperature & Light Indicator

Have complete peace of mind knowing your water is always at a safe temperature with our smart temperature indicator and three-colour light system. No more touching or testing your sterilised water — just glance at the display and feed confidently.

Temperature guide:

  • Yellow: 0–30°C
  • Green: 30–45°C (ideal range)
  • Red: 46°C+ (too hot)
How To Clean

The base of the bottle without the lid is dishwasher safe! Simple wipe the lid with a wet, clean cloth when required.

How To Get An Accurate Temperature Reading

Hold the bottle upside down for at least 10 seconds, then swipe your finger of the lid straight away to read temperature. Repeat this step to confirm the reading is consistent.

1 Year Warranty

Continue to feed safely and confidently, with quality you can trust.
