Hi, my 10yo ds has severe autism, GDD, pica. He doesnt communicate. Pica means he eats anything and everything whether edible or not. Mud, slugs, worms, grass, flowers, his nappy & contents etc. He has had this for as long as i can remember but i assumed as he got older he would grow out of it, unfortunately not! Just the other day i ended up in casualty after he got a hold of screen wash and drank it in the car. I would have been so pleased that he actually got lid off something for first time if it hadnt been so serious. Luckily enough no serious damage done. Next day, got hold of talcum powder and full room was white he was covered head to toe and sitting eating it. In asda he takes things from shelves like sausages etc and eats all including package. Think he has stomach of steel. Saw comm paed on monday and asked her if he would grow out of it, she said some do however some develop it as they get older so im none the wiser. Have any of your dc had pica and now seem to be pica free, lol. :)
