From fickr - part of www.batconservation.org. This is a dog-faced fruit bat. ("I was given the rare and fascinating experience of stepping into some of the bat cages at Cranbrook Institute of Science in Bloomfield Hills, Michigan. Just me, my camera, and 160 live bats.")
Ideas for various squishy balloons. If E could take a walk outside with an adult and fidget with one of these, would it be enough to help him reset? Also, how about a matching activity where he would guess what is inside?
