How contagious is chicken pox, DS (10 months) has about 10 spots on his legs so think he has a fairly mild dose of it but should he avoid all contact with friends etc until it's cleared up. One of my friends is pregnant and she hasn't had chicken pox, so do you think it is safe for her to see me (who has had it before) as long as i am not with DS at the time? Or if we go for a walk and DS is in his pram, is she at risk then?
