Please can someone enlighten me? My friends DS (4) got chicken pox 6 days ago. He has a little brother who hasn't got/had it yet, but she was happily carting chicken pox child around to gymnastics etc today - surely said child is still infectious and little brother certain to be festering with potential chicken pox germs? My two haven't had it and I'm 12 weeks pregnant (not announced yet) so feel a bit sensitive about germs and chicken pox in general, but sure 6 days is not long enough to get over it -please tell me I'm being OTT about it all!!
