Symptoms, or indications of abuse, vary greatly from child to child (or on an individual basis --or in each individual case). Possibly only one, or a few, or none of these symptoms (or indicators) will be readily apparent in a child who IS being abused. 

Absence of any or all of these indicators does NOT mean that a child is NOT being abused. If you suspect there is a problem, do NOT try to diagnose or determine the extent of the problem on your own; please contact a professional immediately.
