Preparing for baby

Hey Mamas, I'm just over half way in my pregnancy now and I've been told my baby is big and that I have a low placenta. Due to those reasons I could need another C Section.

I had a emergency c section with my son and I desperately want to have a natural delivery this time.

Also I desperately want to breast feed this time too, I breast feed for only 2 weeks because I was in absolute agony and I'm stressing again because my nipples are SO SORE and have been SO SORE my whole pregnancy so far and I'm scared I'm gonna have a hard time again.

Do you have any recommendations to help me avoid both of these things... whether you believe it works or not I could do with some help.

Like whats some things at half way in pregnancy I could be doing like any exercises or maybe pregnancy yoga and maybe like putting lanolin on my nipples now to condition them and get them ready? Anything will help.
