Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
Your 2 year old child had
fever, small circular patches on his bottom, and loose stools.
You too had patches on hand, belly ache,
diarrhoea with blood.
It appears that both of you had same infection, it is infectious, and may belongs to
salmonella group or some viral infection.
So far it is O.K. but if there is any urgency you should rush to the hospital. urgency means if the pain is unbearable, or the motions are more.
At least tomorrow i advise you to consult your doctor for diagnosis and treatment.
Wishing for a quick and complete recovery.
Best regards.
