Many children drown, often in very shallow water. It happens in the bath, in garden ponds, paddling pools and water butts.
Supervise children near water at all times. Use a grille on ponds and fill in a garden pond to use as a sand pit. Learn to swim. Do not leave unattended with a young sibling.
Get your child out of the water. Try to get them to cough up any water. If they are not responding call 999.
