While it's understandable you want to help your daughter through diet, MMR vaccine-induced ITP typically resolves on its own within 6-12 weeks in most children. However, some dietary approaches that may support platelet health include:

Foods rich in:
1. Vitamin K (leafy greens)
2. Vitamin B12 (eggs, dairy)
3. Folate (beans, oranges)
4. Iron (lean meats)

Always consult your child's hematologist before starting any supplements, as some can interfere with medications or affect platelet function. Would you like me to provide more specific meal suggestions or information about vaccine-induced ITP?

These dietary suggestions are supportive measures, not replacements for medical treatment.
