Would really appreciate some advise. DS1 has chicken pox (spots started to appear Friday pm). We are meant to be flying to US on Sunday to visit family. Postponed trip as he was ill last time! Hopefully his spots will have crusted over and he won't be contagious by Sunday. Problem is DS2 who hasn't had chicken pox and isn't showing any spots. Dilemma is a) might he already be contagious - don't want to put anyone on flight at risk. b) supposing he became ill while away and we couldn't fly home. We are going for one week only and DH and I both have to be back for work. Is it reasonable or an over reaction to cancel trip because of possible chicken pox? Any advise greatly received. Finding this very stressful. Lost a lot of money last time (insured but excesses, admin fees, etc) not that this is of course the main issue.
