Great sand pit! However buy safe sand. There are 4 grades of sand(Fill, plaster, masonary, and Play) and only one grade is suitable for children's sand boxes:play sand. It should be silica free (depending on the state you live in) and is often sterilized. For this reason it is more expensive than the fill sand that is sold in the hardware store.
Crystalline silica, a colorless mineral, also called quartz, is an ingredient in sand, exposure to crystalline silica dust can cause lung diseases such as silicosis, inhaling airborne crystalline silica dust also has been associated with other diseases such as tuberculosis and lung cancer.
