On first google search I was disappointed. Specific sites for breast feeding came up with absolutely nothing when I typed 'sexual abuse survivor' into the search box. In sections re. 'problems breast feeding' they were all physical issues rather than emotional.
The La Leche League http://www.llli.org/ however did respond to my enquiry, quickly and suggested a podcast by the author of this book;
When Survivors Give Birth: Understanding and Healing the Effects of Early Sexual Abuse on Childbearing Women Penny Simkin, PT, and Phyllis Klaus, CSE, MFT (2005) p.80that I would buy if the country I live in wasn't so corrupt when it comes to parcels arriving/leaving.
...and P.16 of this document is useful http://www.breastfeedingmadesimple.com/thelongshadowHFM.pdf
So far I plan to buy breast sheilds. I have purchased a pump and tried it against my skin to see how it feels and even switched pump on for a second or two to see how tolerable it is. I have bottles for back up (not purchased formula yet) and to feed expressed milk to. I have spoken to my obstetrician about concerns who responded well but after being present at my polypectomy, numerous vaginal examinations and 2 embryo transfers he was shocked the subject hadn't come up before. He assures me I can have space and privacy afterwards for first feeding attempts which will help. I started a thread on Mumsnet which got a good response and on these recommendations I have also bought clothes that are discreet for feeding too which hadn't occurred to me.
I'm still quite determined and at least now I feel a little more prepared.
Thank you for the lovely response to my last post, private and public...good idea to tag/label posts too to reach wider audience.
