DS2 swollowed a glass pebble last year, he was then 5.
he complained that he could still feel it in his throat, so of we trot to A&E.
one xray later, tis in his belly, so they just say keep an eye to ensure safe passge thru his gut, and go back if not passed in several days (not time limit given, butI assumed about 6/7).
anyhooooooooooo
3days later, he stops pooing, I start fretting.
ask advice on here on day 6, they say let him run around and play lots to stimulate his bowel (IIRC at least)....he goes to play on his bike, then runs in the house heading for the loo, like a child poccessed.
BANG, he shot the damn thing out like a bullet (I seriously thought he had cracked the loo it was that loud!)
and he has been fine since
