thanks for using healthcaremagic
I would be pleased to answer your question .
Since there is presence of blood and pus in both in his urine and stool, it is highly necessary that your son should be on some antibiotic treatment as the infection needs to be cleared . you will surely need to continue with the hydration that you are doing by concentrating on the ORS
intake and keep an account of his total volume intake and urine output . In children , the fluid output should be covered with a total good input or intake of water that is keeping your child hydrated is very important .
Make sure you book an appointment with the Pediatrician
as early as possible .
Thanks and take care
