I'd say no, and so would my mother, but when I was two or three I used to eat the stuff anyway. She made it with food colouring, flour, salt and water, so if anything it would have been even more disgusting than your Kool-Aid flavoured playdough. But hey, I also used to eat sand when they took me to the beach, so what do I know?
