The short answer
A 31–36-month-old may open doors and move a stool to reach water, but cannot reliably get themselves out of trouble. Keep a responsible adult within arm’s reach during baths and around pools or other water. Swimming lessons and flotation aids do not replace supervision.

Keep in mind
- Stay within arm’s reach and give one adult clear responsibility for supervision.
- Use barriers and locked access to pools; remove toys that attract children.
- Never rely on lessons, lifeguards or flotation aids instead of close supervision.
What should you prepare before bath time?
Have a towel, soap and clothes ready before your child enters the bath. If you need to answer the door or phone, take your child with you. Check for slippery floors, hot water, an accessible toilet and buckets or containers of water.
What does active supervision look like?
The supervising adult should stay close, attentive and sober; for a young child in water, remain within arm’s reach. Do not assume someone else is watching in a busy setting. Name the adult responsible and hand over responsibility clearly. Drowning can be silent.
How can you block access to a pool?
Use a barrier around the pool with a self-closing, self-latching gate. Remove toys from the water when it is not in use so they do not draw a child back. A door alarm is an extra layer; it does not replace a physical barrier or direct supervision.
What should you do if a child may have been submerged?
If the child is unresponsive or not breathing normally, call emergency services and begin CPR if you are trained. Persistent coughing, difficult breathing, blue or grey skin or lips, altered responsiveness or unusual weakness after a water incident needs urgent medical assessment.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- If a child is missing, check nearby water immediately and call emergency services.
- If a child is unresponsive or not breathing normally after entering water, call emergency services and begin CPR if trained.
