You can safely assume that the whole problem is viral in nature. Give your child ORS solution like electral powder in water, and continue with Wikoryl for her cold. Use Crocin whenever needed for fever. Consult her pediatrician
once to check her weight. Keep giving her breastfeeds. Don't worry, she will soon be all right. Look out for danger signals ... like high fever
, reduced urine output
and not taking feeds, blood in stools or any other problem that is new ... if so, stop taking internet advice and go immediately to a pediatrician.
