What? You think you'll be sitting at home for 6 months twiddling your thumbs bored while your fiance takes care of the baby by herself?
You have to weigh the risks. If you stay at home worse case is not being able to find a job 6 months from now. If you go to work, worse case scenario is that you get sick and bring it back to your family and a baby with a very weak immune system. Is the pediatrics hospital nearby any good?
