I've just found out that we were exposed to chickenpox in the last couple of days. DS is 6 months old. I understand that if he does catch it, it's likely to be quite mild.
However, we're hosting a baby group this week and there will be some much smaller babies and possibly some pregnant women there (who may or may not have had it before).
If ds was exposed yesterday and did happen to catch it, how long would it be before he was infectious? I don't want to panic people, but equally I don't want to expose any vulnerable people to any risks.
