Drinking water should be available indoors and outdoors all day. Milk is a fluid food. Milk should be served at meals or snacks where it is planned as part of the recommended intake for the child. Having ready access to drinking water is especially important on hot days except for infants. Infants who receive human milk or formula should receive extra human milk or formula, not water. Children should learn to drink water from a cup or, without mouthing the fixture, drink from a fountain as they can master these skills. Offer water as often as once an hour. No child should be allowed to have water by sucking continuously on a bottle or Sippy cup as it may interfere with proper nutrition. It is best to have children brush their teeth after at least one feeding. When children who have teeth eat and do not brush their teeth afterward, they should have a drink of water to rinse the food from their teeth. Updated 6/2013.
