She has a raised temp, 38.5 (she is normally under 37), a bit of a nasty cough and she looks pale.
BUT she is a acting normally as in as typically annoying as your average 5yr old
So I phoned her in sick to school, but now I am a bit
because she's not acting ill particularly.
But otoh she's one of those children who almost never acts ill. I've taken her to the docs before with a massive temp and raging tonsillitis and she proceeds to dance for them 
AIBU for keeping her off even though she seems OK?
(OH and I are wfh so we're each taking half a day to watch her so not really an issue)
