I had to keep my daughter home from a field trip. She had woke up, eaten breakfast, and then told us that her tummy hurt. The first thing I did was take her temperature, and sure enough she had a low grade fever. I kept her home. The teacher, bless her heart, calls my house and tells me if I wanted to, I could bring her to the trip myself, so she wouldn't miss the event. I told the teacher if she felt better, I would bring her later in the day, but I want to make sure its not serious. No sooner than the teacher hung up, my daughter was in the bathroom "tossing her cookies." Needless to say, she stayed home with me and on the weekend we went to the field trip exhibit as a family.
