If you've looked at swimming aids for babies, then life jackets are the next best thing. They help to keep your children floating the right way in water and also come with features such as whistles and crotch strap to keep the life jacket in the correct position.

A buoyancy aid is significantly different from a life jacket, and works in a similar way to some baby swimming vests. These are ideal for shallow water and splashing around in a shallow pool. It's important to know the difference between the buoyancy aid and life jacket before purchasing.

Went on our holiday and his confidence grew and grew to the point he even went down slides on his own and felt safe... So many people commented on this and wished they had brought one too. Didn't chaff either, and would definitely recommend. Obviously, you still have to watch them as it's not a life jacket. Thank you for making our holiday so much easier :) used it without armbands!"

Best kids life jackets: all you need to know

What to look for when buying a kids life jacket

With all the technical language and many options to choose from, it can be tricky to know which kids life jacket to buy.

According to the Royal National Lifeboat Institution choosing a lifejacket for the type of activity you are doing is the most important part.

With a large variety of life jackets on the market, it’s good to know what certain features to look for:

Buoyancy: The heavier the child, the more buoyancy needed. Measured in Newtons, 100N is the average for sheltered calm water (and 150N for coastal). Check the life jacket for its recommended amount and also consider what you are buying the life jacket for.

ISO approved: All new life jackets are required to meet the International Standards Organisation standard ISO12402. Older life jackets might have the CE approved mark for full safety and protection, numbered between EN393 to EN399.

Sizing: Buy a life jacket aligned with the RNLI suggestions. It must have a firm fit and be suitable for your child’s current size. Avoid buying for them to grow into in a few weeks or months. If the life jacket is too big, your child’s head will slip right in and provide no support, which is dangerous. To test the correct fit, lift the life jacket around 3cm from your child’s shoulders.

Foam: All children under seven years of age should be in a foam life jacket.

Neck /collar support: Without this important feature - it is not a life jacket.

Strapping: Straps around the crotch ensure that the life jacket is positioned correctly when in use and also helps to prevent the life jacket from rising up.

Whistle: A great feature to have if the wearer needs to call for help and get your attention.

Vibrancy: It’s always handy to have a bright life jacket with additional reflective taping to ensure full visibility. Avoid dark colours as these are hard to see in the water.

What is the difference between a life jacket and a buoyancy aid?

Life jacket

A device that keeps the wearer facing upwards in the water with head support, is strongly recommended for babies, toddlers and kids who struggle in the water by themselves.

Buoyancy aid

A device that aids the buoyancy of the wearer and keeps them afloat. Recommended for older children and more confident kids in the water, as these generally do not provide head support.
