My 22 month daughter has recently been having sulphur like smelling burps with runny smelly bowel movements. ?

Ingest fluids: Sounds like she has gastro-intestinal infection.Make sure she drinks plenty of clear liquids wit sugar and electrolytes.Stop all solid intake.If she is not urinating every 6 hrs take her to a Doctor

?smelly burps?: Ask yourself anything different In her diet at that time. You check on Google for foods that contain high amounts of sulfur compounds in them.
