Thank you for your query on Healthcare Magic.
Your daughter is having gastroenteritis
mostly due to a virus or bacteria.
For vomitings you can give her an anti emetic like ondansetron
in prescribed dose.
Give oral rehydration solutions like Pedialyte
, coconut water, and lemon water to maintain good hydration.
Monitor her hydration statues by skin turgor, urine frequency, and oral cavity moisture.
Consult the doctor for examination and specific treatment.
Hope I have answered your query.
