Thank you for your query on Healthcare Magic.
Your child is having gastroenteritis
The mainstay of treatment is to maintain hydration and to monitor the hydration of the child.
Maintain her hydration by giving sips of oral rehydration solutions like Walyte, coconut water, and lemon water.
Monitor her hydration by activity, urine output, skin turgor, and tongue moisture.
Don't give any self and unprescribed medication.
Consult your Pediatrician
for the assessment of the child and for medication.
Hope I have answered your query.
