I had to have a c-section after being in labor and breastfed in recovery. DD was still covered in blood and "cottage cheese"! Since you are going for a VBAC, you will go into labor naturally so there should not be much delay in your milk if you get a c. I hope you have a successful VBAC. We are unsure about if we will have another baby, but I have already found a VBAC birth center and a VBAC homebirth midwife. We live in a very unfriendly area for VBACs
oh, if you have a successful VBAC, you can nurse as soon as possible. You can ask for delayed cord clamping and still nurse her before her cord is cut. It is recommended by a lot of birth professionals to not cut the cord until it stops pulsing.
I would discuss all this with your OB or MW now and put it in your birth plan.
