After this incident a little while back I was thinking the kids really haven't had much sensory play since we have spent so much time inside. (We limit baths during the winter because of their crazy dry skin.) The snow and ice was still packed on top of the sandboxes at the playgrounds so I brought out a tub of rice and let the kids play, pour and enjoy. They were engrossed for quite a while, but I had to put an end to the fun once Oliver started tossing the rice around. Bonus points: they also enjoyed helping me vacuum and sweep up the mess!
