Thank you for your question.
I am Dr Saha, I shall try my best to help you.
I am sorry for her symptoms.
As her rash is getting better, it is responding to antibiotic.
The vomiting can be due to a few other issues.
There can be gastritis, infection.
Please try to keep her well hydrated.
Peptobismol can be helpful.
ORS, gatorade can be given to balance fluid & electrolyte losses.
If there is no improvement, I would suggest to take an examination by doctor.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
