No one wants their child to be cold, but the harsh reality of energy bills remaining high this winter means that some may have to look for cheaper alternatives to cranking up the central heating to stay warm. There has been much discussion on the Mumsnet forums about how to keep heating costs down and many parents are in agreement that, along with kids' blanket hoodies and insulating your house with the best draught excluder, a children’s hot water bottle is a great option.
A kids' hot water bottle is a brilliant way to keep little ones warm after chilly outdoor adventures or for snuggling up with on the sofa along with the best heated throw after a long day at school. They’re also great for pre-heating beds before settling in for the night, and with designs available from cuddly penguins to snuggly deers, there's a hot water bottle to suit everyone.
There’s no shortage of options when it comes to the best kids’ hot water bottles, so we’ve done all the research for you in order to help you choose the one that’s perfect for your little one. We’ve spent hours collating the tried-and-tested experiences of Mumsnet users - the largest network of parents in the UK - finding out which hot water bottles they love, and which rate highly with consumer reviewers too.
Plus, if you're looking for more ways for the whole family to stay warm this winter, take a look at our round-up of the best winter coats for women, as recommended by Mumsnet users.

What Mumsnet users say
This Teddy Bear Hot Water Bottle from Dunelm brings all the soft, cosy comfort of a teddy bear and combines it with the warmth and comfort of an excellent hot water bottle. Big enough for older children and/or adults (and easy enough to sneak under your best blanket hoodie while working from home while the kids are at school) it comes in three neutral colours.
The super-soft cover helps ensure the hot water bottle stays warm for a long time. Not bad for just £7! Mumsnetters love the whole Teddy Bear range at Dunelm, which also includes a blanket hoodie, throw and cuddle cushion.

What Mumsnet users say
Long hot water bottles are growing in popularity thanks to their versatility - they're very cuddly, with a greater surface area than traditional hot water bottles. For tween and teen girls, they can be worn around the hips to help ease period pain, or draped around the shoulders to supercharge their best dressing gown's cosiness.
This one from Dunelm comes highly recommended, and at a great price. The teddy fabric is soft and snuggly, and at 77cm, it's a generous length for kids.
Best kids' knitted hot water bottle
Lovely, traditional design
Stays warm for a good length of time
Larger size and more grown-up design make it ideal for tweens and teens
The knitted cover may not be quite as snuggly for younger children
Key specs
Price on writing: £10 | Hot water bottle type: Rubber hot water bottle with knitted cover | Size: 2-litre capacity
More of a traditional hot water bottle and cover, this cosy Netagon hot water bottle is available in a handful of fun designs but we love this cute Westie in particular. All come with a thick knitted cover to protect little ones from coming into contact with too much heat.
This is a great no-nonsense way to pre-warm beds before bedtime and reviewers reported that it stayed warm for a long time. And if you do need more long-lasting heat coverage, you can combine it with one of the best electric blankets.
We love the fact that it comes in a presentation box so it would make a lovely gift for any winter birthdays.
Best microwaveable hot water bottle for kids
Great alternative to using hot water
Cute design
Easy to use
Scented
Won’t stay warm for as long as a regular hot water bottle
Key specs
Price on writing: £17 | Hot water bottle type: Microwavable plush polyester | Size: 13 inches
More like a soft toy than a traditional hot water bottle, a Warmies plush is a great way to keep kids warm on cold winter nights and no hot water is needed. Simply heat the lavender-scented bag in the microwave and this adorable sloth will be ready to offer your little one a warm cuddle before they drift off to sleep. Lavender is said to induce sleep (yes, we are willing to try anything!), however, if your child is sensitive to new smells it may not be the best option.
The heat will only last for an hour or so but many parents saw this as a positive as it prevented little ones from getting too hot. Just make sure everyone is already tucked up in bed before you pop it in the microwave to make the most of the heat before it goes cold.
Did you know Warmies also make microwavable slippers? Don't miss their entry in our guide to the best women's slippers!
Best mini kids' hot water bottle
Leakproof
Perfect size to put in pockets
Made with non-toxic materials
Can be filled with cold water and heated in the microwave
Very pricey given its small size
Won’t keep the whole body warm
Key specs
Price on writing: £14 | Hot water bottle type: Silicone water bottle with fabric cover | Size: 18 x 12 x 7 cm | Colours: Pink, grey
As much as we love a visit to Santa’s Grotto or a trip to a winter wonderland, it's hard to fully enjoy it if your kids are feeling the cold. With temperatures set to drop, you may need more than just a pair of the best kids' gloves to keep little hands warm when out and about. This hot water bottle is extremely small so it's perfect for popping into pockets (why not slip one into the pocket of your best heated gilet while out and about in the cold?) The manufacturers claim it’s completely leakproof so it should be safe to use when your child is moving around.
The hot water bottle is designed to be filled with cold water and then heated in the microwave so there’s no need to worry about using boiling water around your little ones. This clever design also means these hot water bottles can be put in the fridge and used to keep your family cool during the hot weather. The downside? You only get one for the price so if you want one for each pocket this could work out quite expensive.
Best novelty kids' hot water bottle
Great choice of designs
Made from natural rubber
Will make a great gift
Some reviewers found the hot water bottle a little tricky to fit back into the cover
Key specs
Price on writing: £14 | Hot water bottle type: Natural rubber hot water bottle with polyester cover| Size: 42 x 35cm
We were almost prompted to take a poll at Mumsnet HQ to try and decide which was the sweetest design when it came to the Country Club Collection! With everything from a cheeky monkey to a cuddly koala, it will prove almost impossible to pick a favourite for your little one.
Not only do they look great, but the covers are super soft and easy to clean and the bottle itself is made from natural rubber. They’re also the perfect size for little ones to snuggle up with and, unsurprisingly, nearly all reviewers reported they were a huge hit with the kids.
Combine with a pair of the best thermal curtains in your child's bedroom to keep them cost-effectively warm and cosy this winter.
Best Christmas hot water bottle for kids
Adorable attention to detail within the design
Choice of characters
A less festive design may get more use year-round
Key specs
Price on writing: £13 | Hot water bottle type: Rubber hot water bottle with plush cover | Size: One-litre capacity | Designs: Penguin, snowman, reindeer
Keep the Christmas spirit up even in January and February with this adorable festive penguin hot water bottle. There's also a reindeer or snowman design too, so you can choose the one your child will love the most. We think it would be ideal for snuggling up with on the sofa whilst finishing up the Christmas chocolates and watching a film.
Many Mumsnet users recommended using a hot water bottle with a cuddly cover like this one as it’s a good way to avoid the traditional rubber surface being too close to young, sensitive skin. The fluffy cover can provide a protective layer against the heat too. It's worth noting though, it is on the small side compared to some other options, but reviewers agreed it was great for youngsters.
Best hot water bottle for older kids
Large capacity
Good for aches, pains and cramps
Variety of designs
Random design dispatched
Key specs
Price on writing: £5 | Hot water bottle type: Rubber hot water bottle with fleece cover | Size: 2 litre capacity | Design: Multi
Whilst younger children are bound to love cuddling up with a novelty hot water bottle, older children may want something a little more grown-up and sophisticated. We love the large capacity and soft, fleece cover of this hot water bottle from ARMA, offering a simple comforting heat source for tweens and teens without feeling too babyish. It comes in a variety of wintry designs, though Amazon will dispatch a random one so it might be better suited to un-fussy teens and tweens.

Are hot water bottles safe for kids to use?
A hot water bottle is a wonderful way to keep warm on cold winter nights. However, safety experts recommend that they should not be given to children under the age of four.
You should never let your child fill the hot water bottle and never fill the hot water bottle with water that is hotter than 40ºC. Also, make sure that you don’t overfill it as it may leak. Hot water bottles made of rubber must have a cover that prevents the rubber from being exposed to skin too.
If pre-warming a child's bed, remove the hot water bottle before he or she settles down for the night. It's recommended that you replace your hot water bottle every five years and, if you're looking for other ways to stay well and warm in winter, the NHS has some great tips.
Which type of hot water bottle is best for kids?
Hot water bottles should not be used near or around children under the age of four. If you opt for a traditional hot water bottle, choose one with a thick cover to prevent your child from coming into direct contact with the hot water bottle itself and always check that the product you are buying meets British Safety Standards.
Parents can be nervous about hot water bottles around children, so opting for a soft toy-style product that comes with a microwavable pouch is a great way to enjoy the benefits of a hot water bottle without dealing with hot water itself. On the downside, these fluffy characters may have a limited shelf life and they might not be the preferred option when they get a bit older.
What’s the best kids’ hot water bottle to buy?
We chose Dunelm’s Teddy Hot Water Bottle as our number one pick. The thick cover offers plenty of protection from the heat of the bottle itself and it's lovely and big, meaning even older and/or taller children can cuddle the full benefit. It’s also excellent value for money and there are matching accessories.
How we chose our recommendations
Because we know that there’s nothing like a real recommendation, we first headed to the Mumsnet forums to find out which kids’ hot water bottles parents were recommending and had bought. We then did some research across the wider web, looking at which kids’ hot water bottles had been featured in ‘best buy’ lists across websites, and what authentic customer reviews said about them. Having collated all that information, we then narrowed our list down to the best kids’ hot water bottles on the market.
