Children in the infant, toddler, and preschool rooms make extensive use of water sensory tables in their classrooms. Water tables are drained at the end of each day, and sprayed with sanitizing solution. Water table toys are washed with soapy water and dried, or put through the dishwasher. Children are to wash their hands in the hand washing sink after water play because their hands are wet, typically have washed their hands before water play because it is offered when they come in from a large-motor time, have toileted and washed their hands. They are discouraged from participating in water play if they have obvious and visible open sores. Water tables are filled each day of their use with fresh tap water.
