You have to take good care of yourself, for the chicken pox issue, I have some advice for you, my son had that vaccination when he was 18 mos. Have you ever exposed to chicken pox yourself? if not, you better hold on for now, because, for the vaccination you are actually inject the virus into the body to create the antibody, so if you don't have the antibody yourself, it is very dangerous for a pregnant women to get chicken pox if you are exposed to that now. ( Of course, if you have that in the past, you have the antibody now, so is safe) Usually it takes 2-3 weeks to complete the cycle and you might don't want to give her the vaccination later on since your second baby is coming soon, for the newborn, their immune system is very weak and is not good if she (2nd one) is exposed to that with such a young age. You might want to ask your pediatrican for more details.
