Anxiety about Due date approaching.

68 days left until due date. It seems so far away yet so close at the same time. My son will be 17 months old when his baby sister arrives and I think the anxiety is starting to set it. Anyone have any advice on having 2 babies so close together??? I'm starting to feel really nervous about everything and I'm still undecided on if I should do a vbac or repeat c section. So I have a lot on my plate at the moment. Some advice, any advice would be greatly helpful to relieve some of this stress and anxiety I'm feeling.
