Anyone have any experience of your children having chickenpox's twice, my youngest has a few possible spots- too early to tell but he has already had them, I know you can in theory have them twice but I am just a bit worried because last time he had them badly and ended up in hospital (only for a day but still not nice) if he had them badly last time are they likely to be bad again if he has got them a second time? Thanks in advance for any advice
