The small size is body sock is for children wearing clothes size 3-5 years.
 
Body Socks are fun, therapeutic sacks constructed from breathable four-way stretch lycra. Body Sox teach both adults and children about gross motor control by providing proprioceptive feedback that leads to a new awareness of the body. Just climb in, close it up or keep your head out, and watch your body make shapes.
 
Body socks will help children with sensory processing disorders to work on "position in space" skills. They must kinesthetically feel what their bodies are doing and how they are coordinating their body movements. They can watch themselves in the mirror or create shadows.
 
The Senco Body Sox provides heavy work/deep pressure input that is both calming and organizing. Through all of these movement activities in the lycra "body sock", they will have comfortable, resistive material to push against and have pushing against them. This will benefit both children with tactile defensiveness as well as the sensory seeking kids.
