She never has before. She hasn't slept since 1pm and has been crabby and I couldn't get her to sleep. Then I noticed she felt hot. Don't have a proper childrens thermometer but just a normal one and took her temp under her arm which was 38.1. Is this high?? What do I do??

We gave her some panadol. I can hear her laughing with DH at the moment.

Is she sick?? What do I do??
