With my birthday been 4th January things don't get back to normal until 5th January for me. I always think I've made it though Christmas and New Year without been ill, can I make it through birthday? I have only ever had flu 1 Christmas which was the Christmas in 2010 and 3 birthdays. Surprisingly I have never been poorly for New Years Eve. My 11th birthday I caught flu on the day while having a party at school and teachers thought I'd chocked on a crisp. Thinking that my parents still took me into McDonald's where I couldn't eat. One year later I went down with flu about 2nd January for my 12th. The last sick birthday was my 20th when I also got flu just after New Years Day.
