How can I safely incorporate a sand pit into my backyard for my children to play in?

To safely incorporate a sand pit into your backyard for your children to play in, ensure the area is level and free of rocks or debris. Use a barrier to contain the sand, such as a wooden frame or plastic border. Regularly inspect the sand for any foreign objects or pests. Provide shade and cover the sand pit when not in use to prevent animals from using it as a litter box. Regularly clean and sanitize the sand to prevent bacteria growth.
