What temperature is your threshold for sending also to activities, whether it's daycare, preschool, library story time, children's museum...

C has had a low fever on and off over the weekend (mostly 100.3-101). It's 100.3 again this morning. Only other symptom is waking up at night and being extra cranky. She's very verbal but hasn't said anything hurts. I know I should probably keep her home today but just need to know if I'm being overly cautious and regular old considerate of other people. She has her gym drop off this morning.
