Protecting our children

Would you be willing to go to jail to protect your child/Children?
My Bijous "F" wanted to pick her up for his scheduled weekend. I sent him an email the day before letting him know she was ill and for him to pick another weekend. He showed up anyway. Brought the police to our home. Insisting that he be able to take her. I said no. I violated the court order because the order has no language about what to do when the child is sick. I now have to do community service and jail time over the weekend.
