Ds (17 months) is on day 3 of chicken pox with more still appearing.I have to take Dd2 to pre school this afternoon and then pop to the shops, is it ok to take Ds out when he's obviously still contagious? I have noone to watch Ds and i don't want Dd2 to miss pre school as this is only her second week. If i put the rain cover over his pushchair then surely he can't pass it on to anyone else?
