At 3am your baby is already crying. You need milk ready in seconds, not in five minutes after the kettle boils, cools, and you test it three times on your wrist. And it's not just nights - it's the flight, the restaurant, the park, the family lunch where there's no microwave and your baby is hungry now. Every time you're away from your kitchen setup, you're scrambling. The milk is either too cold, or you've been heating it so long you've lost track of whether it's still safe. The Warm Nest solves this permanently.

  • Milk stays at exactly 37-40 degrees for hours without a power source or reheating so you always have the temperature your baby expects ready and waiting.
  • Wireless and portable with no kettle, no microwave, no plug, and no adaptor required so it works in a car seat, on a plane, in a park, at a restaurant, and in a hotel room at 2am.
  • No guessing and no testing because you filled it at the right temperature and it stays at that temperature - pour and feed, that's it.
  • Anyone can do the feed because the process is open the lid and pour, so your partner, grandparent, or babysitter doesn't need instructions.
  • Night feeds in seconds with no fumbling in the dark and no standing at the kettle half-asleep because the milk is already ready before you even go to bed.
  • 350ml and 500ml options so the 350ml fits in most cup holders and bags while the 500ml handles a longer outing or a hungrier baby.

Once you've had warm milk ready before the cry starts, you won't understand how you managed without it.

3 Reasons Feeding Away From Home Feels So Hard

Night feeds, outings, travel — here is what is actually making it harder than it needs to be.

Milk cools faster than babies feed

Milk cools faster than babies feed

Breast milk or formula cools quickly - especially during a slow or interrupted feed. By the time your baby takes a break and comes back to the bottle, it has dropped below a comfortable temperature. You either reheat and wait, or push on with cold milk and risk the whole feed failing.

Warning signs
  • Baby pulls off the bottle mid-feed
  • Milk feels lukewarm before the feed is finished
  • You end up reheating the same bottle twice in one sitting
Traditional warmers chain you to one spot

Traditional warmers chain you to one spot

Every plug-in warmer, every kettle, every microwave ties the feed to one location. The moment you leave the house - a cafe, the car, a flight, a family lunch - you lose your setup. You either plan everything around a power point or you scramble when your baby is already crying.

Warning signs
  • You avoid going out during feed times
  • You pack a thermos and flask just to approximate a warm feed
  • You've held a crying baby while waiting for a kettle to boil in an unfamiliar kitchen
Preparation time stretches a crying window

Preparation time stretches a crying window

Heating milk takes time. At 2am when your baby is already crying, every extra minute matters. Boiling a kettle, waiting for it to cool to temperature, testing it - that is a 5-10 minute window between hungry cry and first sip. Every second of that feels longer than it is.

Warning signs
  • You heat milk before your baby wakes just in case
  • You've misjudged temperature and had to start over
  • The whole household is awake by the time the feed actually starts
The Common Thread

All three causes share one root: milk temperature is controlled by the warmer's location - not the baby's needs.

Feed on demand

Feed on demand

When your baby wakes, the milk is already at the right temperature - no reheating, no checking, no delay

From Planning Every Feed Around a Power Point to Just Reaching and Feeding

Nobody tells you that the hardest part of a night feed isn't the tiredness - it's the minutes before it even starts. The preparation. The waiting. The cup that's already gone cold before your baby is halfway through. You're not doing anything wrong. You've just been working without the right tool. Warm Nest removes the preparation window entirely - so every feed starts as soon as your baby needs it.

From Planning Every Feed Around a Power Point to Just Reaching and Feeding

Calmer nights

No kettle, no waiting, no testing on your wrist at 3am. The milk is already at temperature — you just open the lid.

Freedom to leave the house

Cafe, car, flight, park, family lunch - the Warm Nest travels with you. Feed wherever you are, not wherever the kettle is.

Anyone can feed — not just you

Anyone can grab it and feed - partner, grandparent, carer. No instructions needed. Just open and pour.

Why the Usual Fixes Fall Short

Most workarounds work once. Warm Nest works every time.

Why the Usual Fixes Fall Short
The usual fix
Why it fails
What we do instead
Boiling water in a kettle
Takes 5+ minutes, wakes the house, and still requires testing
Warm Nest holds milk ready — no kettle needed, ever
Plug-in jug or bowl warmer
Tied to a wall socket — milk cools the moment you walk away
Fully wireless — warm milk travels with you, not the other way around
Microwave warming
Creates hot spots and can damage breast milk nutrients
Even, consistent heat held at your exact set temperature
Leaving milk in a warm water jug
Water cools, milk temperature drifts — unreliable and messy
Built-in heating element holds temperature stable without water
Room-temperature formula
Many babies reject cooler milk, especially when used to warm feeds
Warm, ready milk every feed - no rejection, no transition fussing
Pre-warming and hoping it stays warm long enough
Rarely times right - too cold before baby feeds or too hot at the start
Constant-temperature mode holds it perfectly from the first minute to the last

Frequently Asked

Warm Nest is a wireless, portable constant-temperature milk warmer. You fill it with breast milk or prepared formula, set your desired temperature using the mechanical dial, and it holds that temperature continuously - without a cord, without boiling water, and without any waiting. It runs on a built-in rechargeable battery so you can use it anywhere in the house or on the go.
Yes - Warm Nest is designed with breast milk in mind. Because it holds milk at a steady, consistent temperature rather than rapidly reheating it, it avoids the hot spots that microwaving can create - hot spots are what damage the proteins and antibodies in breast milk. Set the dial to your preferred serving temperature, add your freshly expressed or refrigerator-cold milk, and it will hold at that level without ever exceeding it. We recommend following standard breast milk safety guidelines: use refrigerated milk within 24 hours, and freshly expressed milk within 4 hours at room temperature. Warm Nest is a holding device, not a reheater - so it works best when the milk is already at or close to serving temperature before it goes in.
The 350mL is ideal for younger newborns who feed smaller volumes more frequently. The 500mL suits older babies with larger feeds, or parents who want more flexibility - including holding enough for two smaller feeds back to back. If you're unsure, the 500mL gives you more room to grow.
Warm Nest runs on a built-in rechargeable battery. How long it lasts between charges depends on how warm you set the dial and how many feeds you run back to back - a higher temperature setting draws more power. Most parents find that charging it each evening as part of a bedtime routine - the same way you would charge a phone - keeps it reliably ready for every night feed and the next day. If you are heading out for the day, a quick charge beforehand is all it needs.
Warm Nest charges via the port on the outer body - the same way most modern small appliances do. We recommend charging it fully before first use, and topping it up each evening so it is always ready. The unit will indicate when it is charging and when it is full. Do not charge near water and do not leave charging unattended overnight as a general precaution with any battery-powered device.
Warm Nest uses a mechanical dial that lets you set your preferred holding temperature. Most parents use it at or around body temperature - roughly 37 degrees Celsius - which is the standard recommended serving temperature for infant milk. The dial gives you control to go slightly warmer or cooler depending on your baby's preference. What it does not do is exceed the set temperature, which is exactly what makes it safer than a microwave or a rapid warmer.
Warm Nest is designed as a constant-temperature holder, not an overnight storage vessel. We recommend preparing milk fresh and placing it in Warm Nest immediately before a feed, rather than leaving prepared milk sitting for extended periods. Follow standard guidelines for safe formula preparation and breast milk storage.
The inner cup is hand-wash only. Remove the cup from the outer body and wash it with warm soapy water after each use. Rinse thoroughly and allow to air dry before reassembling. Do not submerge the outer body or battery unit in water. The lid and seal ring can also be hand-washed separately.
US orders typically arrive in approximately 7 days from the date of your order. All Parent Nest orders include free shipping with no minimum spend required. You'll receive a tracking link by email as soon as your order is dispatched.
We stand behind every product in the Parent Nest range. If Warm Nest isn't working for your family within 30 days of delivery, contact us and we'll make it right — whether that's a replacement, a return, or a refund. No difficult process, no long waits. Parent Nest exists to solve problems, not create new ones.
