My Dd loved a bit of go cat
DS liked to help feed his grandma's dog - spoon the Winalot into her bowl and then served gets to lick it
DS in his time has also eaten sponges, chalk, no less than four coins, a Lego, a Nerf dart, soil, sand, Playdoh, glitter, confetti, bird seed, an entire page of newspaper, a frozen fish finger, a whole green pepper including the stalk and seeds, and a candle.
No ill effects and I stopped ringing the GP after the third or fourth time.
Coins, magnets, batteries (especially those button batteries), and anything sharp needs to assessed at A&E but most everything else works its own way out.
