i don't really have any advice but i think you seem to have covered lots of possibilities & opportunities for improving things this time round. the other thing you can work on is remembering that you have done this before. it might take time, but hopefully this time is easier &, if not, you know that it can still be successful even if it takes a while to establish things.

i agree with MP as well - make sure you let them know if you need help. most people i've spoken to who have 2 or more have said they are mostly left to their own devices second time round. and nothing wrong with reinforcing your plan with your ob/the midwives before you go in to theatre. i have a feeling too that your milk might be faster considering it's a scheduled c-section & less traumatic for the body than an emergency c-section
