Try to give her medicines like antacid gels/ lansoprazole
in recommended dosage. You have to continue with oral ondenstron/ domperidone
for vomiting. These medicines will do if its just a gastritis
. Also give her bland diet.
As a child keeps vomiting more and more, it tends to become yellow- that indicates bile.
But if vomiting never stops and all are yellow, she has to be investigated- Ultrasound
abdomen- to rule out any surgical causes.
Hope you find my answer helpful.
Wish a speedy recovery for your kid.
