Honestly I never pack until I'm in labor. When it starts I usually take a shower put on some makeup pack my bag and make my phone calls. This is my 5th so I know I have time until the contractions are 5 min apart.
You don't have to pack ahead of time but I will say that in some ways it's helpful. You could easily forget something in the rush, excitement of heading to the hospital I packed my bag for both myself and the diaper bag for my daughter when I was 36 weeks. So I knew that I would have everything She and I needed.It really paid off but every momma is different. Do what you think is best.
Thanks ladies I packed today finally just wanted to be ready. My doctor told me when I go into labor I am not really spouse to wait at home since my first pregnancy I had an emergency C-section.
