Reminds me of the time my friend's 2 yr old swallowed a wood screw. Almost choked to death on it but ended up swallowing it. Dr. gave her something to drink that would make it pass with no damage, but it wasn't showing up in the ol' stinky diaper for a couple days... They had one x-ray showing that screw about belly button area. So he brought her over and I ran my metal detector over her belly and sure enough, it was still in there, nice loud BEEP in her belly. Still after a week, no screw in the diaper. Went back to Dr. for another Xray, and GONE. Their babysitter didn't check the turds like she'd said she would/did. LOL
