Practical guidance on keeping children safe around water, from garden ponds to open water and swimming pools.
Water Safety is the awareness and precautions that protect children around water such as pools, baths, rivers, and the sea, where drowning can happen quickly and silently.
Drowning is one of the leading causes of accidental death in children. Young children can drown in as little as a few centimetres of water, and it often happens silently. Supervision, education, and environmental awareness are the most effective prevention measures.
Children are drawn to water and may not understand the dangers. Drowning can occur in seconds and is often silent — there is rarely splashing or calling for help. Risks exist in gardens (ponds, paddling pools), at swimming pools, and near open water such as rivers, canals, and the sea.
In your child's behaviour
Supervise constantly around water
Never leave young children unattended near any water — including baths, paddling pools, ponds, and buckets. Active supervision means watching continuously, not checking intermittently.
Invest in swimming lessons
Teach your child to swim as early as is practical. Learning water survival skills — floating, treading water, and getting out safely — is as important as learning strokes.
Teach open water rules
Explain the dangers of cold water shock, hidden currents, and unseen obstacles. Teach the 'float to live' technique promoted by the RNLI and agree that open water is never entered alone.
In immediate danger: call 999. For non-emergency police matters, call 101.

Myth: If a child was drowning, you would hear them shout or see them splashing about.
Fact: Drowning is usually fast and silent. A struggling child typically cannot call out or wave for help and can quietly slip under the surface within seconds, which is why RNLI and CAPT (Child Accident Prevention Trust) both describe real drowning as silent, not the noisy struggle shown in films.
Myth: A bath, paddling pool, or garden pond is too shallow for a young child to actually drown in.
Fact: CAPT and RoSPA warn that babies and toddlers can drown in just a few centimetres of water, because they may not yet have the reflex to lift their head clear on their own, so even shallow water needs arm's-reach supervision at all times.
Myth: Armbands, or a child who can already swim, mean you do not need to watch them closely.
Fact: RoSPA is clear that inflatables and swimming aids are not a substitute for supervision or swimming ability, and that even children who swim well should still be actively supervised whenever they are in or near water.
Stay within arm's reach any time your child is in or near water, including the bath, a paddling pool, or by a garden pond. At this age a child can drown in seconds and in only a few centimetres of water, so watching from another room or glancing over occasionally is not enough. Empty paddling pools straight after use and treat ponds, water butts, and buckets as hazards to fence off, cover, or remove.
Children this age can understand simple water safety rules but will forget them the moment they get excited, so they still need close, active supervision rather than just being told what not to do. Use this stage to build real swimming and floating skills with a qualified teacher, and agree simple rules before they go near water, such as asking permission first and never going in alone.
Start introducing the specific risks of open water: rivers, lakes, canals, and the sea are colder and far less predictable than a pool, with hidden currents and sudden changes in depth. Teach the RNLI's Float to Live technique, leaning back with the airway clear and gently moving the hands and legs to stay afloat, as the first thing to do if they ever get into trouble in the water.
As children begin swimming with friends without an adult right beside them, agree ground rules for open water: check with you first, never swim alone, and never jump or dive into water of unknown depth. Reinforce that being a confident pool swimmer does not make cold-water shock or currents any less dangerous, and that Float to Live is still the right first response if they get into difficulty.
