Premmie & PND

Debbie
I'm 33+4 and have a slow leak. They want to bring my elective section forward to possibly next week. (4 baby 3 section!) 
My 2nd baby was premmie 33weeks, and I suffered pnd. I felt like there was no bond. 
How can I stop that happening again?? I'm so worried about it. I also wanted to breastfed but it was pretty impossible before!
