When they go to the nicu they always give formula, given the condition of baby (and sometimes mom) when they are brought there the main thing is just to get them some nourishment and as soon as possible. Hospital policy also plays a big role in this. Many people think if you want to pump that you tell the nurse and they'll bring it right over, only issue is usually the nurse is told by you, then she must tell the Dr, the Dr then has to write orders for the breast pump, and then it can be given to you.
Since you already plan on having a c section.. this baby should make it to full term so it probably womt have to go to the nicu. So after your all sown up you will see your baby. And you can just begin to breast feed then.
