Thank you for your query,
Your child is having Gastroenteritis
which could be viral or bacterial.
You maintain the hydration status of the child by giving oral rehydrating solutions like ORS
, lemon water, coconut water and dal water.
After each vomiting
or loose motions you can give 100 to 200 ml sips by sips to balance the losses of water and electrolytes in stools and in vomitus.
Monitor her hydration status, activity and her urine output.
Consult your Pediatrician
for examination and for specific treatment.
Hope i have answered your query.
