Dc3 has chicken pox. He's 9 months old and started getting spots yesterday, now he is covered, but not too I'll. Dc1 and 2 have not had chicken pox, but have been exposed to it lots of times without getting it. I know dc is contagious until the blisters scab and fall off, but how careful do I need to be? I've sent dc1 to school so did the school run this morning (its tricky but not impossible to get someone else to do it). Feel a bit confused about quarantine, any advice? I'm sure I should know all this!
