This morning when I got up and changed Jacob's diaper, I found that it was full of blood. His next diaper had blood in it, too, so I took him in for an appointment. So far they don't know what is going on. His urine sample did have traces of blood in it, and they are sending it in for further testing. Right now we are just watching him to see if he seems to be in pain or if he has another bloody diaper. We are hoping that it was just a kidney stone that passed and that there will be no further problems. He's been acting fine today, so that is a good sign. That kid likes to keep us on our toes!
