One mum tester said, “I think this kit is well worth the money and a great investment for new parents. The fact all of this comes in one convenient box along with some other access like bottles, a bottle warming bag and dummies is amazing and just what you need for baby!!”

It also comes with a setting to keep the bottle warm for up to 30 minutes after heating.

Mum tester Natalie found this very useful when it came to travel, thanks to the USB-powered feature for charging on the go, commenting, "it’s perfect for when you are travelling and need to make bottles on the go and it’s also useful at home as you can keep a full days’ worth of feeds in the fridge and just heat the bottles up as and when required.” With three heat settings and a generous formula compartment, it offers versatility. 

The NUPEAA warmer's silicone lid keeps the heating plate sterile for quick and hygienic warming. Parent tester particularly loved the product's silent operation and lightweight design.

This all-in-one feature reduces clutter on your kitchen countertop while providing essential functionalities for feeding and hygiene.

Featuring four different warming functions, including a 'keep warm' setting for up to 45 minutes, this device ensures that your baby's feed is always at the ideal temperature. With a MAM Easy Start Anti-Colic Baby Bottle, a MAM Slow Flow Teat, and a MAM Baby Soother included, it's great value for money. 

Real parent testers have praised its convenience and effectiveness, highlighting its ability to streamline feeding routines and reduce stress. Its multiple functions, including electric and microwave sterilisation, make it suitable for various scenarios, from home use to travel. Mum tester Katie agreed, saying “able to use at home or travelling as a microwave steriliser which was great and really convenient as it is super compact so hardly takes up any room.”

While some would have appreciated clearer water level indicators and a more compact design, overall, they did find this product very easy to use. Mum Jenny commented, “there doesn’t appear to be a maximum line for the water to be filled to, which would make using the steriliser a bit easier to use. I find myself having to measure out the recommended 200ml in a measuring jug to get the correct amount of water.”

Doesn’t take up too much room on the worktop either.”

Compatible with Dr. Brown bottles and most other brands, it’s operated with an easy-to-use LED control panel with a touch keypad and button start function. It efficiently heats multiple bottles before requiring a refill, and the audio and visual alerts signal the end of the warming cycle.

It also has the ability to keep water warm for up to four hours making it ideal for suitable for short trips and outings, with one mum tester commenting that it “keeps water really hot and its ideal for travel.” 
Although it's specifically designed for use with Tommee Tippee Closer to Nature Bottles, it can accommodate multiple food containers, and parents particularly loved how convenient it was for both bottle feeding and transitioning to solid foods.

The thermos-like design holds approximately two bottles worth of hot water, ensuring you have everything you need while on the move. While it lacks temperature control, its affordability and practicality make it a worthwhile investment for parents, although some parents would have also liked it to hold more water, with one mum commenting, “doesn’t hold a massive amount of hot water and feel it does get cold after about 4/5 hours.”

The digital display monitors the liquid temperature as it warms, ensuring precise heating up to 37°C and maintaining this temperature for 30 minutes, with one parent saying, “we checked the temperature a few times after reading some reviews but it was always perfect.”

User-friendly and compact, this bottle warmer requires no water reservoir or measurements, making it ideal for busy parents. Simply twist the bottle into the base, flip the unit, and press to start warming. It's efficient and doesn't clutter your countertop. Plus, there's no need for batteries; just plug it in and go! 

It's a convenient solution for warming breast milk or formula, whether you're at home or on the go. One mum tester said, “we're only formula feeding once per day so are using ready made and once in the bottle this little gadget warms it to the perfect temperature in literally a couple of minutes.” The main downside was how tricky it was to clean, with one mum saying, “only thing that's not great is cleaning it. You can't detach the heat plate to clean. Makes sense really as it needs to stay attached to warm the milk. If you're a germ freak and really want to sterilise everything, it's just something to be aware of.”

Pros

  • Easy to use
  • Compact
  • Comes with 5 bottle adaptors

Cons

  • Wipe clean only

Its one-touch design and compact size make the Nuby Bottle Warmer ideal for travel, fitting all sizes, shapes, and brands of bottles. Whether you’re warming breast milk, formula, or baby food, even from frozen, this warmer gets the job done in as little as three minutes.

To use, simply add water following the instructions, load your bottle using the provided basket, and touch to start. It's important to note that the unit requires a 10-minute cooldown between uses and the power button should be pressed firmly to operate. One mum tester found this very easy to use, commenting, “So easy to use, just use the measuring jug each time and flick the button then just wait! I have noticed over time the wait time for the warming has become a little longer each time but still great!”

Parents love how quick this is when it comes to heating compared to traditional warmers. The main downside they found was that it doesn’t have an off switch, with one mum commenting, “it doesn’t auto turn off the light stays on and the only way to stop it is turn it off at the wall.”

Pros

  • Great for travel
  • Easy to use
  • Works quickly

Best baby bottle warmer with smart control

The Philips Avent Bottle Warmer can warm milk in just three minutes, defrost frozen milk and baby food, and keep warmed milk at the ideal temperature for up to 60 minutes. Compatible with Philips Avent bottles and most other brands, parents found this warmer very easy to use, with one mum commenting, “it is very easy to use and keeps the milk nice and warm without overheating it and making it to hot.”

Featuring smart temperature control, this warmer ensures that milk and baby food are heated evenly without any hotspots. The temperature control also prevents overheating and adjusts the heating pattern for fast warming. 

The clear indicator light lets you know when the milk has reached the perfect temperature, and the warmer automatically shuts off after 60 minutes to prevent dry-boiling. Parents love how this streamlines bottle feeding routines and saves time. The only downside is that warming time can vary a lot depending on the starting temperature which is not ideal for night feeds as one parent found. “Sometimes the milk is 35 sometimes it is 23 and this can be frustrating especially during the night feeds with a screaming baby.” They said.

Pros

  • Smart temperature control
  • Defrosts frozen milk and food
  • Fits most bottles

Cons

  • No water gauge

How does a baby bottle warmer work?

Traditional baby bottle warmers have a central vessel where you put your baby's bottle in. You then fill around the bottle with water and switch on the power, which enables the heating element in the bottle warmer to heat the water and bottled milk in turn.

With a baby bottle warmer, you can take the guesswork out of warming your baby's bottle to the ideal temperature with a thermostat and clear indicator light that goes off when it's just right.

Suitable for breast milk, formula, and even baby food in some cases, make sure the bottle warmer you're looking to buy can accommodate the bottles you have at home. Many come with adapters for holding different shapes and sizes of bottles and jars.

What is the ideal temperature for baby milk?

The ideal temperature for breast milk is 37°C. Not only is it easier to digest for tiny tummies, saving discomfort at bedtime. But babies prefer their milk at natural body temperature. If you've stored your expressed breast milk in the fridge or freezer, using a bottle warmer will bring it back to this temperature for your little one.

The same temperature applies to formula milk too. You can use a bottle warmer with ready-to-use formulas that can be stored in the fridge. However, if you're using powder formula, it's recommended to make up each formula fresh for your baby. In comparison to breast milk, the formula isn't sterile. You should make it up using hot water to kill the bacteria and use it within two hours once cooled to room temperature.

Do you really need a bottle warmer?

While it's not completely necessary, using a bottle warmer is one of the best and safest ways to warm your baby's bottle. Not only that, but a bottle warmer is:

Quick: Baby bottle warmers are designed to be quick and efficient, so your baby isn't left crying or hungry for too long - something mum and baby can both appreciate! Some bottle warmers can reach the perfect temperature in as little as 90 seconds.

Easy to use: There's very little hassle involved; you just need to put in the bottle, fill it with water if the reservoir is low, switch it on, and go. Some baby bottle warmers have pre-programmed settings to suit different bottles and starting temperatures, whilst others just have a one-touch operation to save the faff if you're consistently heating the same type of bottles.

Reliable: Baby bottle warmers are designed to evenly heat up your baby's milk every time without the risk of overheating. Some will even keep your baby's bottle warm for a long period of time with auto-shutoff and overheating protection to prevent anything from getting too warm.

Transportable: As well as being generally more convenient, some bottle warmers are designed to easily fit in your baby's changing bag and carry on the go. These can be USB charged, require no power at all, or be mains-powered but light enough to carry with you when visiting family and friends.

Is a bottle warmer better than using the microwave?

It is definitely better. Warming your milk in the microwave is not recommended. Warming in the microwave can result in uneven heating as the milk is directly heated - bottle warmers heat the water surrounding the bottle instead. This transfer of heat is a much safer process – bottles heated in the microwave may continue to ‘boil’ after being removed and could end up being too hot for your baby’s sensitive mouth. Not only that but overheating the milk can damage baby bottles and destroy the natural nutrients contained in breast milk.

If you’re not using a bottle warmer, it’s recommended to replicate the process by filling a jug or bowl with warm water and placing your baby’s bottle inside for no more than 15 minutes.
