Best hot water bottle for kids

Children hate feeling cold, so a kids' hot water bottle is a brilliant way to keep little ones warm after chilly outdoor adventures. A cosy hot water bottle is great for snuggling up with on the sofa after a long day at school and for pre-heating beds before settling in for the night. And it's a lot cheaper than cranking up the central heating.

But hot water and small children sounds like a worrying combination and there are understandably many questions around safety. Our useful buyer's guide answers all these concerns and our roundup features hot water bottles that have been tried, tested and recommended by real parents. 

If you're looking for other ways to keep your kids warm this winter, check out our handpicked guides to the best kids' blanket hoodies, kids thermal underwear, kids' winter hats, kids' gloves and kids' snow boots.

Here are the best kids’ hot water bottles to buy this year. 

1. Best overall kids’ hot water bottle: Warmies Fully Heatable Soft Toy Llama Scented with French Lavender

Warmies Llama hot water bottle

Price: £12 | Buy now from Amazon

"My DCs have microwavable cuddly toys with a lavender bag in them. Would have thought they are safer than a hotwater bottle" - recommended by Mumsnet user, christywhisty

"They are warm and comforting but don't leave a rash if you cuddle with them for too long" - tried and tested by Mumsnet user, Pimmsy

Mumsnetters rave about Warmies across the forums. More like a soft toy than a traditional hot water bottle, it's a great way to keep kids warm on cold winter nights and no hot water is needed. Once you heat the lavender scented bag in the microwave, this adorable llama will be ready to offer your little one a warm cuddle before they drift off to sleep.  And lavender is said to induce sleep (yes, we are willing to try anything). Make sure the kids are tucked up nicely before you pop it in the microwave as the heat will only last for about an hour or so. 

Key specs

  • Hot water bottle type: Microwavable plush with lavender scent
  • Size: 34 x 29 cm

2. Best budget kids’ hot water bottle: Cozy Creatures Super Soft Childs Hot Water Bottle & Cover

Cozy Creatures bear hot water bottle

Price £8 | Buy now from Amazon

Family- and budget-friendly, this Cozy Creatures hot water bottle is both adorable and affordable. The mini hot water bottle holds 250ml of water and comes with a choice of cute covers: a super-soft bear or a bright yellow duck (complete with padded arms and legs for a snuggly feel). If it gets grubby, you can chuck in the washing machine (after removing the rubber bottle). Being a smaller hottie, it will only retain its heat for a few hours but after a frosty day in the playground or just before bedtime, a quick blast of heat is all you need. A few reviews mention that the bottle is a little tricky to get into the cover. 

Key specs

  • Hot water bottle type: Natural rubber
  • Size: 4.8 x 14.22 x 10.67cm

3. Best kids’ hot water bottle with a knitted cover: Netagon 2-Litre Hot Water Bottle and Soft Knitted Cover

Netagon knitted hot water bottle

Price £12 | Buy now from Amazon

More of a traditional hot water bottle and cover, this cosy product is available in a handful of fun designs but we love this cute pooch in particular. All come with a thick knitted cover to protect small hands. A great pick for pre-warming beds before bedtime, it may even help your kids stay in bed. We’ll cross everything for you. It comes in a presentation box so it would make a thoughtful winter gift. 

Key specs

  • Hot water bottle type: Rubber hot water bottle with knitted cover
  • Size: 2-litre capacity

4. Best portable kids’ hot water bottles: Harry Potter Mini Hedwig Hot Water Bottle

Hedwig hot water bottle

Price £15 | Buy now from Amazon

Harry Potter fans will love this cute Hedwig hot water bottle and what better way to keep your little wizards warm this winter. They'll be sure to want to take it with them on their next sleepover. This hot water bottle caused quite the stir on the Mumsnet forums in the run up to Christmas. One mum was desperate to track one down as a present for her daughter and Mumsnetters searched high and low to make her Christmas wish come true. It warmed our hearts and Hedwig can warm your kids' hands too. Snap one up while it's in stock!

Key specs

  • Hot water bottle type: Rubber hot water bottle, polyester and cotton cover
  • Size: 21.5 x 12.5cm

5. Best microwavable hot water bottle for kids: Warmies Microwavable Sheep

Warmies microwavable sheep

Price £13 | Buy now from Amazon

"My mum bought my DSs some 'Fuzzy Friends' for Christmas. They have a little wheat pouch inside that you heat in the microwave (as long as you follow the instructions and don't over heat them, they're fine) and the boys love them. We've used hot water bottles for the last few years but the fuzzy friends are a lot easier" - recommended by Mumsnet user, zisforzebra

This super-soft plush sheep can provide plenty of comfort to young children when needed. After 90 seconds in the microwave, Warmies release a calming scent from the dried French lavender (and millet grain) insert and stay warm for almost an hour - ideal for bedtime routines, though we're sure it will be snuggled even without its warm belly. In the summer months, you can pop the inner pouch in the freezer to keep your kids cool. For parents, removing hot water from the equation is another benefit. 

Key specs

  • Hot water bottle type: Microwavable plush toy, millet grain and dried lavender insert
  • Size: 15.2 x 17.8 x 20.3 

6. Best kids’ hot water bottle for cuddles: Baby Worm Baby Bottle

Baby worm hot water bottle

Price £25 | Buy now from YuYu

These wriggly worms are a hit with parents and kids and come in four bright colours - blue, orange, green, and pink. The long, slim hot water bottle can fit around the body for maximum comfort, mimicking a giant hug and it's said to be useful for targeting pain relief in specific areas around the stomach and back. Keeping it in good condition is a doddle as the cover can be washed at 30°c. It's more expensive than some of the others on our list but it's a versatile and comforting buy that can be used by the whole family. 

Key specs

  • Hot water bottle type: Sri Lankan rubber bottle, cotton cover
  • Size: 75 x 12.5cm

7. Best fluffy kids’ hot water bottle: CityComfort Hot Water Bottle with Cute and Fluffy Cover

CityComfort hot water bottle

Price £12 | Buy now from Amazon

"I'd recommend one of those cuddly covers - it stops the bottle being too close to the skin and helps retain the heat a bit longer too" - recommended by Mumsnet user, Iklboo

One Mumsnetter wisely says that a bottle with a cuddly cover is a good option to avoid the traditional rubber surface being too close to young skin. A ribbed, anti-leak hot water bottle and an extra fluffy cover can provide a protective layer against the heat and this sturdy hot water bottle can hold up to a litre of water. Little ones can choose between a beige sheep and a green dinosaur. We'd recommend letting them pick - it might help with bedtime resistance at the end of a busy day.  

Key specs

  • Hot water bottle type: Natural rubber bottle, fleece cover
  • Size: 45 x 35cm

8. Best novelty kids’ hot water bottle: Country Club Novelty Animal Hot Water Bottle

Novelty animal hot water bottle

Price £11 | Buy now from Amazon

"We gave him a very warm (hot) water bottle when he went to bed, encased in a furry dog shaped cover. DH screwed the top on (Geoff Capes could not have got it off) and took it out when we went to bed (it was usually cold by then anyway. DS is 3" - Iklboo

Kids can snuggle up on the sofa after a day at school with one of these cute, toasty animals. Whether they like polar bears, dogs, penguins, rabbits or leopards, Country Club has it covered (in pretty pastel colours to boot). These would make a really lovely gift and a welcome addition to any soft toy collection. And when the kids are out and you're feeling the chill yourself, we won't judge you if you snuggle up on the sofa.

Key specs

  • Hot water bottle type: Natural rubber, polyester cover
  • Size: 42 x 35cm 

Are hot water bottles safe for kids to use?

A hot water bottle is a wonderful way to keep the whole family warm on cold winter nights. However, it is vital that babies and children are kept safe when using them. 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. Hot water bottles made of rubber must have a cover that prevents the rubber from being exposed. If pre-warming a cot or child's bed, remove the hot water bottle before he or she settles down for the night. Don't let children under four hold a hot water bottle. It's recommended that you replace your snuggle buddy 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. 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. You can keep your family warm and safe this winter and beyond by following the guidelines outlined above when using a hot water bottle for children over four years old. 

What’s the best kids’ hot water bottle to buy? 

Because standard hot water bottles often don’t sit right with many parents of young children, the Warmies Fully Heatable Soft Toy Scented with French Lavender is our top kids' hottie. Mumsnet users love the Warmies range, and the lavender scent is great for calming busy little minds. It's cute, affordable, super-soft, and retains a sufficient amount of heat to take the chill off. It should last a few winters before the kids are in their junior years and want something more grown up. Fortunately, our guide provides plenty of options for that time too. 

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 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.
