I think that the parent always knows their own child best. If your child is not acting themselves, or is complaining of not feeling well when normally they are anxious to come to school, then I would keep them home for the day to watch and evaluate.
The policies that MFISD have are few, but very specific: A child...
1. Must be fever free for 24 hours after having a fever of 100.0 or more
2. May not stay at school if vomiting or having persistant diarrhea.
3. Must be free from infection, or in the process of treatment (antibiotics), before returning to school.
Anytime you have a question, be sure and contact me, I would be happy to talk with you. 830-798-3678
