Not only do the children at Our Neighborhood love our two, very large and awkwardly sized sandboxes, but so does my own child. Our sandboxes have no bottom, and drain easily with no outside force, supporting them to be clean. The former language of "Sandboxes with bottoms which prevent drainage shall be covered when not in use." should be kept. rather than change it in such a way that sand play will be more inaccessible for children in any childcare setting
