I don't know why you people dumping
steroids in to kids blood stream. They are nothing but toxins may aggravate infection or other side effects.
Unless there's is an indication don't use it. Other they cause fluid retention,
dyspnea, obesity, opportunistic infections etc.
Nose bleed in a kid may be due to nasal pricking need to apply a pressure , avoid dry environment means use moisturizer.
If symptoms not improved please consult your
ENT specialist he will examine and do nasal packing and treat you accordingly.
Hope I have answered your query.
