Chicken pox been doing the rounds at dd's nursery. She's had it before as has ds but he was only 4 months old so apparently likely to get it again. Anyway, just noticed three spots in his armpit and he's been cranky today. Could not be I suppose but gut instinct is it's the pox. We're going to the Canaries on Saturday. What to do? Can we just go anyway??? Not v fair on other passengers... But OH NO first holiday for three years!!! Advice please.
