Hello,
Really, it is very difficult to look after kids when they are ill. Moreover, it appears to be a viral illness as all of them are suffering almost same symptoms.
The following are the recommendations of treatment for viral illness in kids:
1) Symptomatic treatments are Tylenol, Ibuprofen, cough syrup, and nasal decongestants
2) Adequate hydration is to be maintained
3)
Liquid diet is to be encouraged more
4) Hand hygiene is very important
Regarding rash with fever, causes are many that include even some serious infections like varicella (
chicken pox), hemorrhagic fevers et cetera. So, it would be better to
consult a pediatrician for
fever with rash.
Calf cramping is due to
viral fever and subsides as illness comes down. So, no worry is necessary in this respect.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Pallavi.m
