When should the nursery be done?

JKPLMS

SO and I started the nursery last week...we just about have all the painting done, just a few touch-ups to do. Our furniture is ordered and should be here by the end of this week and I bought the window valences. We have the bedding on our registry so I don't know when we will be getting that but I feel like I need to get the room done for some reason. I know I still have 4 months but I keep hearing those stories about women who have their babies 5 weeks early and then I want to get it done even more! When is everyone trying to finish their rooms by?
