It's easy and very inexpensive to create opportunities for sensory play for your children. You could put snow, dried rice, beans or pasta in a large baking tray. In warmer weather, fill a tub with water and give kids sponges, squirt bottles, etc. Playing with clay also helps calm children as they use the muscles in their hands to relieve stress. Older children might enjoy knitting or crocheting. And how about that bubble wrap?
