My five year old swallowed a small marble what should i do? does she need to see a doctor in person?

Yes, if swallowing..: is a problem, she continues to complain of pain in the chest in the region of the breast bone, the narrowest area of the esophagus, or she has any problem with breathing. Usually a marble will pass via the stool in a few days. Consult your doctor if the marble was actually magnetized or was a coin shaped battery, which could cause complications.

? how big ?: Most smooth sided objects that make it into the stomach will pass without problems within 3-5 days.If she can drink fluids without problems and has no problems with breathing/choking, you can monitor this at home. For objects with jagged edges I feed them stewed okra which forms a slimy coat around the objects and helps it pass. That should not be needed.

Seek care : You should seek care at a ER or pediatric hospital. A simple X-ray may be needed to determine the object the size and location. A child can swallow more than one thing. Deterring the location and size is key. Best of luck.
