Best kids' water bottles at a glance

How did we choose the best water bottles?

When testing and selecting the best water bottles for kids, we considered value for money, capacity, size, comfort for kids, materials and how leakproof they are. Our Best lists are compiled by qualified and experienced parenting journalists. They rely on a number of sources, including our independent reviews, testing undertaken during the MadeForMums Awards, and feedback from our home testing panel and Top Testers Club. Each year thousands of products are put through their paces by hundreds of parents across the country on behalf of MadeForMums, to ensure we’re bringing you honest and true reviews and recommendations. Our list is not an ordered ranking. Instead, it is a carefully selected group of tried-and-tested products, each of which we believe is best for a different situation or requirement. We don't just tell you what is best, we help you discover what is best for your family.

Ion8-water-bottle-with-child-tester

Why we chose it: A practical, parent-approved bottle that’s easy for children to open, secure when closed and designed to avoid leaks in bags.

We’re a big fan of Ion8 bottles in our house. Leak proof, easy to clean as no straw to clean and dishwasher safe. We’ve got the plastic ones (they do metal too) and have had no issues with scratches etc, even the one that my daughter takes to school everyday.

What to keep in mind

Key specs: Capacity: 400ml | Size: 7cm x 6.7cm x 17cm | Material: Plastic | BPA free: Yes

This bottle is great for hygiene thanks to its spout cover. It flips open easily and locks closed using just one finger, while the locking system means there’s less risk of it popping open and spilling everywhere. Parent tester Hannah also rated this bottle, saying: "No leaks and super easy to open and keep clean, both my 1 and 3 year old (pictured above) can use them with ease."

The vented, smooth liquid flow helps your child drink at a comfortable speed, and the soft grip makes it easier for little hands to hold. The bottle is the width of a can, so it should fit neatly in car cup holders too.

The plastic is phthalate free, non-toxic and BPA free. As well as the Space design pictured, there are other cute designs to choose from, including unicorn and dinosaur options.

Little girl testing the Nuby Incredible Gulp Tritan Bottle

Why we chose it: This no-spill cup is easy for younger children to open and close independently, with a soft-flex spout and clear Tritan bottle.

I love that it's spill-proof, I feel safe having it in my daughter's bag. My daughter finds it easy to open and close herself.

What to keep in mind

Key specs: Suitable age: 18+ months | Capacity: 360ml | Size: 10cm x 7.5cm x 21cm | Material: Silicone | BPA free: Yes

This Nuby Incredible Gulp Tritan bottle is useful for keeping younger children hydrated wherever they are. The soft-flex silicone spout is dentist-approved and pops open by pushing a button, making it easy for children to drink from. The cover helps prevent spills when it’s closed.

The bottle itself is made from Tritan, a BPA-free, shatter-proof plastic that’s dishwasher safe and microwave safe. It’s as clear as glass, so you can easily keep track of how much water your child is drinking.

Parent tester Emma, mum of 3 year old twins, says "it's good you can get replacement straws/tops/spouts as my daughter likes to chew on hers!" If you feel like you're constantly replacing bottles because your child chews them, replacement components could be a more cost-effective option.

Munchkin water bottle

Why we chose it: This brand new kids' bottle is insulated, extremely easy to open, close and carry. It's an ideal first water bottle for toddlers.

We haven't experienced any spills and the little carry handle means she happily carries it around herself.

What to keep in mind

Key specs: Suitable age: 24m+ | Capacity: 355ml | Size: 21.5cm x 7.5cm x 7.5cm | Material: Plastic and silicone | BPA free: Yes

The Munchkin Stay Cool insulated bottle is a handy option for keeping drinks cool when you're out and about. Its double-wall insulation helps keep water chilled for longer, while the 355ml capacity is a good size for toddlers. The flexible straw is gentle on gums, and the flip-top lid has a handy carry handle for little hands.

The leak-resistant valve helps prevent spills, while the durable plastic construction means it can cope with being dropped.

Parent tester Hollie, mum to Margot, says: "It's a lovely vibrant design and my daughter found it so easy to open and close herself, which makes my life a lot easier. We haven't experienced any spills and the little carry handle means she happily carries it around herself. It's really easy to wash and as it's plastic it just bounces if she drops it. She found it slightly harder to suck water through than some other bottles, but this is likely due to the leak-proof valve."

If you’re on the hunt for a kids stainless steel water bottle, this Yeti kids water bottle keeps drinks ice cool all day. It’s designed to be leak proof as long as the lid is properly closed, and we like the easy carry handle, which makes it simple for smaller hands to grab and go.

This one is extremely durable too, so it can handle being dropped by little ones. It’s dishwasher safe, which takes the hassle out of cleaning. It is on the pricier side compared to others in our best kids water bottle UK list, but it comes with a 5 year warranty and a choice of 20 different colours.

Sistema Twist 'n' Sip being tested laid out on a counter

Why we chose it: A budget-friendly, easy-clean bottle with a hygienic twist lid that works well for sports and school.

I think they are such a good quality, a good price and they last my children ages...I like that they come in different colours as well and they are easy to wash.

Key specs: Capacity: 330ml | Size: 6.1cm x 6.4cm x 16.2cm | Material: Plastic | BPA free: Yes

If you're looking for an affordable water bottle, the Sistema Twist 'n' Sip is a practical option. Its lid allows the bottle to be opened and closed without fingers touching the sipper tip, making it more hygienic than bottles where children need to touch the drinking spout.

We also think it's a great sports water bottle for kids, thanks to its clever shape that adapts well to the hand. It can be cleaned in the dishwasher, is microwave safe without the lid, and is phthalate and BPA free.

Little Life Kids Water Bottle being tested by little boy

Why we chose it: A child-friendly straw bottle with a wrist strap, side measurements and replaceable components.

It's not the biggest but any more and my boys would find it overwhelming, being faced with that amount to drink. It easily fits in a school bag or handbag being that size too

The Tritan material is shatter-proof, durable, stain and odour-resistant. It’s also dishwasher safe. If needed, you can buy replacement straws, lids and other components as parts wear out.

Product shot of SHO kids water bottles

Why we chose it: A durable insulated stainless steel bottle with 2 lids, bright designs and a lifetime guarantee.

SHO bottles are great. They’re metal not plastic, so they don’t crack. They come with a straw lid too, so great for getting water into kids on hot days. They're also leak proof - our daughter (2) has been using the same one since before she turned 1 and it’s been brilliant.

Key specs: Capacity: 260ml/370ml | Size: 6.5cm x 6.5cm x 19cm / 7cm x 7cm x 23cm | Material: Stainless steel | BPA free: Yes

We're really impressed by this reusable bottle from SHO. Its stainless steel design is durable and insulated, keeping drinks cold for 24 hours and hot drinks warm for 12 hours. It comes with 2 lids: a screw lid and a straw lid. The screw lid is 100% leakproof, while the straw lid is spill proof.

The bottle also comes with a lifetime guarantee, so although it’s expensive, there’s reassurance that it’s built to last. We also like the bright designs, including animals, dinosaurs, dragons, pirates and mermaids. You can personalise the bottle with your child’s name for an additional £10.

Key specs: Capacity: 350ml | Size: 7cm x 19cm | Material: Stainless steel | BPA free: Yes

We like this robust water bottle from onegreenbottle. The bottle is insulated, so similarly to the SHO bottle above, it will maintain the temperature of cold drinks for 24 hours and hot drinks for 12 hours.

As our tester mentions above, it’s easy to clean. It’s also a good size for a toddler to wrap their hands around, and the 350ml capacity is a practical size to keep younger children hydrated.

Onegreenbottle is a strong eco-friendly choice too. For every bottle sold, the company reclaims 50 single use plastic bottles from the ocean. The company is certified B-Corp, its supply chain is single-use plastic free and the bottle is 100% recyclable.

Why we chose it: A reliable insulated bottle that keeps drinks cold and has a child-friendly flip-top straw lid.

What we like

What to keep in mind

Key specs: Capacity: 355ml | Size: 7cm x 7cm x 19cm | Material: Stainless steel | BPA free: Yes

If you're looking for a bottle that'll keep cold drinks cold, these flip-top Funtainer drinks bottles are a good option. Using Thermos technology, they claim to keep drinks cold for up to 12 hours, and we’ve seen that for ourselves: MFM's Gemma used one of these with her toddler during a heatwave and it became a must have.

The bottle features a flip-top with a push button that can be operated by small hands. Inside, there’s a soft silicone straw. With the lid properly clipped on, it’s leakproof, but with the lid off the straw can drip or spray. To wash it thoroughly, you’ll need to take a few pieces apart, but no more than others on this list. The bottle also comes with a 5 year guarantee.

What to consider when buying a kids' water bottle so it lasts

What types of kids water bottles are there?

The two main types of water bottles are plastic and stainless steel. If you are purchasing a plastic water bottle, you should ensure it's BPA and phthalate free. Stainless steel is a more sustainable and environmentally-friendly option, but these tend to be slightly more expensive.

Other than material, you can also choose between different caps. There are sippy caps, straw caps, sports caps or simple open bottle tops. This comes down to preference; there’s no right or wrong cap, so choose whatever suits you and your child best.

How big should a kids water bottle be?

Depending on the age of the child, they'll need a bottle with a different capacity. For a toddler, the ideal capacity is around 300-350ml. There’s not much need for anything bigger, as it may be too heavy for them to carry.

A school-age child should have a 500-750ml bottle. This ensures they have enough water to last them throughout their school day.
