Hi Dear, Ideally give her only liquids right now since she is having temperature and may vomit out everything. Frequent vomiting can lead her to weakness and dehydration, also kids get tired and frustrated.
Secondly, if she is not accepting allopathic medicine, you can go for homoeopathic treatment for her, it is absolutely children friendly and harmless....
Next Steps
you also continue with cold water strips over her head to avoid temperature raise. And sip by sip ORS as well.
