DS1 swallowed 10 cents when he was 3 and the Dr said he should poop it out within a few days. He was mortified that we'd have to check his poo to see if it came out so he always did a poo when we weren't paying attention and flush it really quick LOL, so we had no idea if it ever came out or not, but when he was 6 he had a pelvic xray and nothing showed up on it so I assumed that it did come out. Over the years in nappies I've also seen beads, lego knex and a wheel off a matchbox car It shouldn't cause her any trouble, but I'd let them know JIC.
