Important Note: All adapters come with an additional insert sealing ring to ensure a tight connection between the baby bottle and the adapter. The device will only be 100% leak-proof if both sealing rings (heating plate and adapter) are used. If there is any leakage, you may have forgotten to install a sealing ring.

Adapter Use: For a more secure fit, screw adapter into the warmer tightly first, and then screw in your bottle.

Using Breast Milk with the Portable Bottle Warmer

Great news - You can heat breast milk in the bottle warmer. We recommend setting it to 37°C, our lowest heating option. The slow heat technology preserves the nutrients in the milk and prevents any hotspots. Make sure the breast milk is thawed before heating.

Using Formula with the Portable Bottle Warmer

Warm the water first using the portable bottle warmer. Once it reaches the desired temperature, add your formula.

Note: Do not add the formula before heating the water, as it will stick to the heating plate and prevent the bottle from warming correctly

How Long Will My Bottle Take to Heat?

Your bottle will typically take approx. 5-10 minutes* to heat, using slow heat technology to ensure no hot spots. Our warmer will also hold the water at your desired temperature until you're ready. Choose from 37°c, 40°c, or 45°c.

The exact time may vary depending on the initial temperature of the liquid, the selected temperature setting and the volume of liquid. We recommend filling bottles with room temperature or warm water when heading out & about. Chilled water will take longer.

Heating times and performance are based on room-temperature water/milk, as well as approximately 150ml of liquid.

Pour water or milk into your baby bottle.
Screw the warmer onto the bottle: Keep the bottle upright while attaching the warmer, with the Lil Moo warmer upside down on top of the baby bottle.
Invert the bottle: Once the warmer is securely attached, turn the baby bottle upside down so the Lil Moo warmer is upright beneath the bottle.
Select the desired temperature: Press the button to choose between 37°C, 40°C, or 45°C.
Wait for the beep: The temperature will gradually rise and display on the warmer. It will beep once the set temperature is reached.
Test the liquid: Before feeding your baby, test the liquid against your skin to ensure it is at a safe temperature

Reassemble

After wiping down your Lil Moo place the lid back on firmly (there is a trick for this) so that they stay secure on the bottle warmer:

1. Put on the dust cover normally

2. Press in with the centre of the thumb to create a vacuum

3. Slightly lift the edge of the dust cover so that air escapes and a vacuum is formed

Formula Feeding – Important Instructions

If heating formula, it’s essential you:

Heat the water only first.
Add formula after the water is heated.

Why this matters:

Heating formula mixed with water causes residue to stick to the heating plate, which interferes with the unit’s ability to heat effectively and can damage the plate over time.

To clean your portable bottle warmer while out and about, follow these simple steps:

Wipe down. Use a soft, damp cloth or wipe to wipe the exterior of the warmer. Avoid getting any water into the heating unit.
Remove any spills: If there are any spills or stains on the warmer, gently wipe them away with a cloth dampened with warm, soapy water.
Dry thoroughly: After cleaning, ensure the warmer is completely dry before storing or using it again.
Clean the heating plate: Clean the heating plate with a soft, damp clot or wipe. Be sure it is completely dry before use.
Regular maintenance: Perform regular cleaning to keep your portable bottle warmer in good condition and ensure its longevity.

Sterilising

Unplug and cool down: Before cleaning, ensure the warmer is unplugged from charger and has cooled down completely to avoid any accidents.
Prepare a sterilizing solution: You can use a commercial sterilizing solution or prepare a mixture of water and sterilizing tablets or use boiling water.
Disassemble: Remove lid and rubber seal.
Soak: Place the sterilising solution or boiling water on the heating plate but do not submerge the unit. Soak rubber seal separately.
Soak for recommended time: Follow the manufacturer's instructions if using solution or soak with boiling water for at least 5 minutes.
Rinse thoroughly: Tip water/ solution out and wipe down to ensure all liquid is removed.
Air dry: Allow all the parts to air dry completely before reassembling or using the portable bottle warmer again.
Perform regular sterilization: It's essential to sterilize your portable bottle warmer regularly, especially if it comes into contact with milk or formula, to prevent the growth of harmful bacteria.

Watch video instructions for cleaning

Important: Before use, ensure placement of the sealing ring is correctly installed, refer to instruction manual for full details.

Make sure your wall adapter has a voltage of 5V-2A or 5V-3A and charge it to 100% before use.

If heating formula, it’s essential to:

Heat the water only first.
Add formula after the water is heated.

Why this matters:

Heating formula mixed with water causes residue to stick to the heating plate, which interferes with the unit’s ability to heat effectively and can damage the plate over time.

Adapter Use: For a more secure fit, screw adapter into the warmer tightly first, and then screw in your bottle.

How will you know when the warmer is fully charged? It will display '100'. Remember to ensure you are using the correct wall plug to allow it to charge fully!

How long will one charge last? It depends on the volume of liquid being used, the starting temperature and how long you are holding the liquid at that chosen temperature. However, on average we see one charge warming approximately 3-4 bottles.

You could warm your babies bottle before you leave home, but it'll be cold by the time your baby actually wants it. That's the trap - a bottle warmed at home has a shelf life of about an hour, but hunger doesn't run to your schedule. It hits in the supermarket queue, in the car on the motorway, at the park with no kitchen in sight. Every parent knows the specific panic of a screaming baby and a cold bottle in your hand and nowhere to fix it. The warmer means that moment simply doesn't happen to you anymore.

Plus, Lil Moo parents have found warm bottles over cold tend to lead to better sleep, more comfort, and more milk intake!

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.

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.

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.

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.

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

The whole thing takes about 30 seconds.

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.

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.

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)

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

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.
