Hi DS is 22 months and since mid Jan, he has had 3 illnesses with temperatures. The first one lasted 12 days and it was awful and finally diagnosed as flu. He then was fever free for 10 days then got another temperature with cough and cold which lasted 36 hours. Now today 19 days later he again has another temp (38.5) he is currently asleep but his older brother 5 has a hacking cold so I'm assuming he has just caught another virus but is this normal? I've never had this many illnesses with temperatures in such short succession with my eldest. Anyone else experience this during winter? I'm exhausted and constantly worried about him.
