My baby is so sick): she's had diarrhea 6 times today so far and now has a diaper rash because of it and has a runny/stuffy nose and I have the same thing right now and my body and head hurts so I'm sure hers does too on top of a sore throat.. should I take her to the ER? Or just keep giving her tylenol until it goes away? She's 6 and a half months
