Why not take sensory play outside the box with sock bean bags? We have so many mismatched socks around this house so this was a great upcycle project. We have a sensory box with dried split peas and lima beans. Have to admit not one of my favorite sensory boxes - the split peas feel so nice running through your fingers but they are very hard to clean up.
My toddler was able to help make the bean bags. I put some small paper cups in the bean box. She scooped up beans and poured them into the small socks. I used a rubber band to secure the beans inside the sock and turned the sock inside out over the sack of beans. Voila - bean bag! We repeated this process 4 times.
The toddler quickly grabbed the bean bags and began throwing them around the room. There was lots of throwing, squatting, reaching and carrying of the bean bags. It entertained her for some time.
The older kids quickly found a cure for their boredom and practiced juggling with the bean bag balls. The baby sock bean bags were the perfect size for small hands to juggle.
