Hi, Welcome to Healthcare Magic forum,
Your baby seems to be having some viral diarrhea
. You are doing the right thing by giving her plenty of fluids which you need to continue. It usually takes 7 to 10 days for it to subside. You can add on zinc containing syrup (syp. Z&D 0.5 ml twice a day) for 14 days. Continue good hydration. Stools will slowly improve. Rash
can be taken care off by applying siloderm cream. Hope your child gets well soon.
