My 20 months kid started to have a fever last night, his underarm temperature was measured up to 101.4. He is now around 99.8...It has lasted for 15 hours. But he can eat and behave like normal, just a little bit irritable. One or two hour ago, I found those rash on his leg and arm. Don’t know what’s this, so we can’t decide whether it is worth to take him to urgent care ( it’s Saturday today)...😢 Does any mom know what’s this and have some suggestions? Thank you very much!
