The short answer
At 25–30 months, a child may open doors or move a stool to reach water. The same rule applies in a bath, bucket, paddling pool, pond, sea or swimming pool: a responsible adult must supervise continuously and stay within arm’s reach while a toddler is in or near water. Swim lessons, armbands, inflatable rings and older siblings do not replace adult supervision.

Keep in mind
- Supervision must stay continuous and focused; clearly hand over if another adult takes over.
- Empty baths, buckets and paddling pools after use; restrict access to larger pools with a physical barrier.
- Breathing difficulty, blue colour, altered alertness or persistent coughing after submersion requires urgent assessment.
What makes bath time safer?
Have a towel, soap and clean clothes ready before your child gets into the water. If you need to leave for the door or phone, take your child with you; a few seconds alone is not safe. Restrict access to baths and toilets, and also prevent slips and scalds.
What does continuous supervision mean?
The adult responsible for watching must stay close, attentive and unimpaired; for a toddler in or near water, stay within arm’s reach. If another adult takes over, say so clearly by name. An older sibling is not the designated supervisor.
How can you prevent unsupervised access to water?
Empty buckets and paddling pools after use and turn them upside down. For a home pool, use a barrier that fully surrounds it, with a self-closing, self-latching gate. Door alarms may add a layer but do not replace a fence.
Are armbands, rings and life jackets equivalent?
Inflatable armbands and rings do not make a child drown-proof and cannot replace an adult within reach. For boating and suitable open-water activities, use a properly fitted, approved life jacket. A child who has had lessons still needs close supervision.
What should you do if submersion is suspected?
If the child is unresponsive or not breathing normally, call your local emergency service and start CPR if trained. Even if the child seems well after an incident, seek urgent assessment for persistent coughing, breathing difficulty, blue lips, altered alertness or unusual weakness.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Not breathing normally, unresponsive, blue lips, seizure or altered alertness after submersion.
- Persistent cough, chest retractions, unusual drowsiness or marked weakness.
- The child does not return to usual behaviour after a water incident.
