  1. This child presents with many low risk factors: (1) exact timing of ingestion is known, (2) she is asymptomatic, (3) the battery has moved beyond the esophagus presumably into the stomach, and (4) it’s a small (</= 12 mm) battery. I agree that she can be discharged home with appropriate anticipatory guidance, although "48 hours return for Xrays" is likely too fast.
