It is called messy May sensory box. Somehow both of us ended up covered in corn starch. But it was so fun Jman cried when it went away and begged for it again.
This month is construction theme. Some rocks, beans, corn meal and corn starch and throw in some tractors. My little boys dream. He was a little hesitant about getting in there and kept trying to clean off, but that didn't last long. He finally was willing to get really into it. He wanted to get in the box as usual but I did not want to clean that up so he stayed out this time. I think this one is a favorite. May have to keep it through June because I don't see myself changing it.
