How big was the piece? If it was pretty small, give 1/2 inch of laxatone or petromalt and watch very carefully. If it was a big piece, think about going into the vet right away if you are sure it was ingested. Unfortunately styro won't show up on a x-ray. If your kid paws at his/mouth repeatedly or has thin stringy stools take the fert into the vet immediately. (S)he might need surgery. Hoping it turns out ok, Matthew in CO. [Posted in FML issue 3455]
