Thank you for your query,
Your child is having dysentery
due to a bacteria.
This infection needs antibiotic treatment.
Continue the medication as advised by Pediatrician
Try to increase giving oral rehydration solutions like Pedialyte
, coconut water, lemon water to replace the losses.
Your child is having signs of dehydration
and consult your Pediatrician as she may need correction of dehydration with IV fluids.
Hope I have answered your query.
