Both my kids got it DD1 got it when she was 2 1/2 and DD2 got it off her when she was 6 months old. DD1 got it every bad even though she had the immunisation. DD2 wasnt so bad even though she never had the immunisation. The first signs for us were flu like symptoms and whinginess and temp then a day later first spots appeared, DD1 got first spots in the nappy area then on her leg then shoulder. DD2 got spots first on her leg and torso. Hope this helps.
