Mud
Childs choice of "tools" (toys or natures toys)
What better way to not only let your kiddo not only get some sensory time, but to also get out and explore nature!
If you have toys/items outside already, there shouldn’t be any reason you’d need to add or put anything out, who knows, your kiddo may prefer to use things they find in the mud anyway!
Children often get creative on their own using things they see or themselves. Theo sat right down in the middle of the mud mess and tried picking up huge handfuls, kicked it around and stomped in it. He sure did like this messy one!
