Hi, Since both you and your daughter had the same rash sequentially, its probably a viral rash (rash associated with some viral fever). She may also have develop some fever. Its quite common for children to be fussy, irritable and refuse to feed during initial 2-3 days of such illness - nothing to worry, if she is otherwise active and feeding somewhat normally. I used to give calamine lotion for applying twice daily over rash (you can buy without prescription), antihistamines like hydroxizine to relieve itching and paracetamol for fever for such cases. Get back to your doctor if she develops high grade and continuous fever / very lethargic / not at all feeding; otherwise everything will settle in a couple of days Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Muhammed Aslam T. K, Pediatrician
