hiya, sorry to hear he has chicken pox, good news for you, i work as nursery room leader, keep him warm and the spots can heal as quick as 4 days. soon as the last one scabs over, take him back, he wont he contagious. he is only contagious when getting spots. as for ur little man being ill now, he will have a fab immune system when he gets to school.
chin up... and put heating on
