Create as many tunnels as possible to create an enclosed world to explore. Take fabric tunnels that can be bought at the store and connect them to more tunnels that you make yourself. You can make tents and tunnels by using sheets connected to the couches, large boxes with one or both ends opened. Set the tunnels up in a confined space so that they are not tempted to run around the tunnels, but are made to crawl through the tunnels. Explain and demonstrate how to crawl through the tunnels and tents. Use animals or cars as enticements to crawl through the tunnel to get the toy. Many teachers and parents have found that their child has increased attention inside the confined space of a tunnel.
