Thank you for your query on Healthcare Magic.
Your child seems developed gastroenteritis
because of contamination of food most probably.
The mainstay of treatment is to control vomitings and to maintain her hydration.
You can give an oral anti emetic like ondansetron
in prescribed dose to stop the vomitings.
Give sips of oral rehydration solutions like Pedialyte
, coconut water, and lemon water to maintain her hydration.
Monitor her hydration by activity, moisture of oral cavity, skin turgor, and urine output.
For fever you can give Tylenol
in prescribed dose.
Consult your Pediatrician
for the physical examination, assessment of her hydration status, and for specific treatment.
Hope I have answered your query.
