He's seven and a half - well beyond the age of "knowing better." Yet Son #3 managed to swallow a magnetic rock several weeks ago. He was never the kid who put foreign objects in his mouth, even as a baby, but lo and behold, this time he did.
A couple of phone calls to our pediatrician and the local emergency room confirmed what we suspected. Since it was only one magnet and no other metal was involved, we just had to wait it out - pun intended. We were on high alert all week but no sign of the magnet. Not exactly something you can ask the school nurse to monitor, y'know?
After a week our doctor recommended an xray to be sure the magnet passed. That's not something you want to discover during an MRI years down the road. Xray showed all was clear.
I guess this means I can no longer threaten to stick him to the side of the refrigerator if he misbehaves.
