Have you and your DH had it?

I would put off TTCing this month because chicken pox isn't very friendly in early preg (I can't remember what effect it has but I have read that it isn't good). And make sure that if you or DH have any symptoms get them checked because it can turn into shingles in adults.

Otherwise, check that his fingernails are cut short so that he doesn't cause damage to his skin if he itches and if he does scratch any chicken pox poxs can get infected really easily and scar so use some sort of antiseptic cream on them.

Also, a friend tells me that letting them run naked (or as close as possible to it) cuts down on the discomfort.
