Neuroticlady - I'm so glad you went for your walk with the dogs. It does make things seem more normal doesn't it.
Like your ds, our dd was a much wanted, long waited for baby. I had a picture in my mind of the perfect mother I was going to be. I spent two and a half years dreaming, wishing, imagining and building that picture. Obviously, the reality was never, ever going to match.
The second I saw my daughter, I think I felt shock. Pure and simple shock.
I struggled with brestfeeding too, and gave up after a month as it was severely affecting my ability to bond with dd. I began dreading her waking up because I knew that I would have to feed her.
I can honestly say that it took at least 2 months before I started to really bond with her. Up until then, I put on a really good show for everyone else of being a devoted, doting mother. She was always beautifully dressed, my house was clean and tidy and I baked cakes every time someone came round. Inside I was falling apart. It wasn't until I began to accept that this was just a different life - not the ideal life, or the perfect life that I began to relax around dd and really become her mother, rather than her carer.
The one thing I wish I'd done, was talk to someone about how I felt about stopping up breastfeeding. Even now, almost 3 and a half years on, I still feel a sense of loss and bereavement. I can only imagine the feelings you are wrestling with re. breast feeding and breast cancer. Do you feel that your breasts had "let you down" somehow with the cancer, and have now done it again by not letting you breastfeed?
Could your GP refer you to someone to talk to about this - maybe one of the cancer support groups or breastfeeding support groups in Oz?
Keep going, but give yourself a break. You don't need to be the perfect parent. You just need to be good enough.
