Thank you for your query on Healthcare Magic.
Your child is having gastroenteritis
which could be due to a virus.
Happy to hear there are no more vomitings.
You start giving sips of oral rehydration fluids sip by sip to maintain the hydration and child urine output.
Monitor her hydration by her activity, skin turgor, wet tongue , and urine output.
Probiotics like saccharomuces or lactobacillus
and zinc can be given after consulting your Pediatrician
Hope I have answered your query.
