my toddler swallowed a quarter sized flat plastic magnet that went with a little magnetic pizza making toy 36 hours ago.It was plastic based, and pretty thin (thinner than cardboard but thicker than paper) we went to the emergency room and they said not to worry about it and wait for it to pass. We live in Japan so communication is an issue. Since he swallowed the magnet, he has been a little more fussy than usual, though eating and drinking normally. Not sleeping well for 2 nights. He just had his morning poo and said it was a bit painful, but looked the same as far as size and consistency. there were some dark bits that were about the color of the magnet part, but nothing the size or shape of the original toy. My question is could that be bits of the digested magnet or should i expect to see something along the lines of it coming out whole, as it went in?
