The school policy at my DD's school is if your child is sent home sick then they have to be fever free for 24 hours without medication. So obviously no kid can come back the very next day. This parent has sent her child to school the next day TWICE. Her son was sent home for throwing up and she sent him back the next day. Then the next week he was sent home with a fever and once again she sent him back the next day. What is wrong with these people? Would you ever send your kid to school if they were sent home sick the day before, even though school policy stated not to?
