Michelle,
anyway i found this:
Is my baby at risk if I get chicken pox close to my due date?
If you get chicken pox early in the third trimester of pregnancy, your baby will probably be fine. Here's why: About five days after you come down with chicken pox, your body develops antibodies to the virus and passes them to your baby through the placenta, offering protection that his own immature immune system couldn't provide on its own.
If you develop chicken pox five to 21 days before your baby is born, he might develop chicken pox, but because of the antibodies he received from you, it's much less likely to be serious. (Some babies exposed to chicken pox in utero don't have any signs of infection at birth but develop a case of shingles during infancy or early childhood without having had chicken pox. Fortunately, it's usually not serious.)
The most risky time to come down with chicken pox is between five days before giving birth and two days after delivery, because then your baby is exposed to the virus but doesn't have time to receive antibodies from you. In this case, there's a high chance (estimated at 17 to 30 percent) that he'll develop what's called neonatal varicella, or newborn chicken pox, which can be serious and even life threatening – especially if left untreated.
Fortunately, your baby's risk of a severe case can be greatly reduced if he gets a shot of varicella zoster immune globulin (VZIG), a blood product that contains chicken pox antibodies. (You may also see this referred to as VariZIG, which is the brand name of the VZIG product that's currently available in the United States.) Your baby will be given the shot soon after birth if your chicken pox showed up within five days of delivery or as soon as you discover your rash if it's within two days after delivery.
If your newborn shows any sign of developing the infection – such as coming down with a fever or showing a rash of even a few spots – he'll be treated intravenously with the antiviral drug acyclovir.
