Thanks for your query.
Your child is having blood in stools which suggest dysentry
Most important is to maintain hydration.
This is good that child is active.
Give oral rehydration solution sip by sip after each loose stool
,give coconut water,lemonade,curd,boiled potato,banana,rice porridge.
Give lactobaccilus sachet for 2 to 3 days.
Watch for signs of dehydration
If stool sample shows any infection your doctor will give a course of antibiotic.
Wishing your child good health.
