good evening, as ur doctor has advised , its very important to maintain the childs hydration status thru ORS
. watch for signs of dehydration- decreased activity, dry skin
, dry eyes
and oral cavity, sunken eyes, excessive thirst etc. these conditions need urgent medical care. currently i would advice you to get a stool for reducing substance test done if its been missed. if its positive , then we will have to need to give the child lactose free diet. as of now u can try with the supportive medicines like zinc drops and oral enterogermina
, the doses of which have to be decided on the weight of the child, so kindly review with ur doctor.
