My last 2 babies were both vbacs. I was up literally... well with my first vbac, I gave birth standing up and they had to force me to sit down to transfer me over to the hospital and then I got up again as soon as I was in the hospital.
With my last baby, I was literally up a few minutes after giving birth so I can try to deliver the placenta and then go see the baby in the nicu because they had to take him due to inhaling amniotic fluid.
