Nick missed his 4th day of school

Hello,
I guess scared is all that I can think of these days. We are so proud that Nick has started kindergarten and he absolutely loves it. I can actually enjoy some quiet time at home and get my work done without interuptions. There is not a minute that goes by while Nick is at school that I can not help but wonder.... is he washing his hands, did he touch anything, did someone sneeze on him. I understand these things are out of my control, but letting go, is not easy. So, what happened? Nick definitely had some dirarhea on Wednesday during the day. He went to bed Wed. night and woke up in the middle of the night and threw up. We told him Thursday morning that he could not go to school and he was so upset. He was worried that he might be 'star of the day' and he would miss it. We explained to him that star of the day would be someone attending school that day and he would have another chance. Greg called clinic and Nurse Clarie said to give him some zofran (anti-nausea medicine we usually give him before chemo). She said as long as he does not have a fever, to continue to watch him and keep liquids in him. The zofran seemed to help his stomach pain and stop the throwing up. He went to the bathroom quite a bit, but we think he was just getting rid of the virus he had. He feels much better today and the kids are actually off today, which is good, because I do not think I would have sent him anyways. We are planning on enjoying the long weekend with the kids and some outdoor time. Karen
