DS has chicken pox. I first thought he had been bitten (DH has, just been staying near coast) but it's spread like wildfire in less than 24h and classic chicken pox. First of all, what can help him? He seems fine - bit tired, and starting to scratch a little (spots turning to blisters now). How long does he have to stay off school etc? Also, other DSs (2 and 11m) seem pox free - will it come later, or if they don't have it now will they not get it? Thanks :)
