27wks pregnant & my nephew have chicken pox. I had chicken pox when I was 3. I am just worried that it would harm my baby if a member has chicken pox?

Relax. Your fetus is sharing the antibodies you developed when you had cpx at 3, so neither you or your baby have any risk. Even if you never had cpx, the risk to a developing fetus at that stage (if it got it) is small. There are cases where minor skin scarring was noted, but cpx is not the big risk that many other infections are to a fetus.
