I have been trying to get a 2 year old with cerebral palsy to tolerate being positioned over the horse's barrel prone and he always cries. Today he was so interested in a new toy that he forgot to be afraid. I gave him a picture card to hold that shows a moving horse when the card is opened and closed. He had much better head control in this position than I expected and he was able to hold the card with weight on his forearms while my side walker held onto his legs. We were even able to do this while the horse was walking.
The technique used to make the card is called scanimation and the book Gallop is filled with these moving animals.
