All three of my children have come out with chicken pox spots at the same time. Everything I can see online states there's quite a long incubation period and chicken pox is only contagious up to 2 days before the spots appear. So they can't have caught it from one another. I'm confused as to how they could have all caught it at the same time. Has this happened to anyone else? A bit worried the school will think I'm lying! I wasn't planning on making a GP app as I don't want to waste their time when there's nothing they can do, the children are well in themselves other than itchy spots, and it's very clearly chicken pox.would I be best making an app for the GP to confirm? Not sure they will write a letter for me to give to school though, and I wouldn't want to ask they're busy enough as is
