I am so sorry that you are feeling this way and completely understand. A a previous comment said, this is more common than we realise and it was only when I was eventually very open and honest about what a tough time I had that others also told me about the difficulties that they experienced.
At the outset there was no question for me that I would breast feed for a minimum of six months. Initially latching on was a real problem and after a couple of sessions with a wonderful NHS breast feeding advisor we seemed to have that cracked. That said I was still finding breast feeding at best uncomfortable and, for the majority of the time, downright painful. I saw another breast feeding consultant and she confirmed that I had thrush. I was so naive I didn't even know you could get thrush in your beasts - in hindsight it was a given that I'd get it as I always get thrush from antibiotics and was given a large dose post-operatively after my emergency c-section.
I really battled with the thrush (and mastitis) for almost 5 months, (I was also partially bottle feeding when I really couldn't face breast feeding) and finally called it quits. I felt that I'd really failed my son and didn't get any support from the health visitors at the Stormont clinic. My son had mild eczema and despite explaining how hard it was, I just got back the standard line about the importance of breast feeding to avoid things like eczema - just what I didn't need!! Fortunately my GP was very good and was very clear that if you can do it that's great but breast feeding is just one of many things that make for a happy and healthy baby - and mother!
During all those months my poor little boy had terrible thrush in his mouth - and probably internally as well - and I kept being told to just keep putting a particular thrush gel in his mouth post feeds. On reflection I can't imagine that was that great for him on such an ongoing basis.
I generally felt terrible the first few months of my son's life and talking about it after my second son was born, the health professionals believe I had PND. So you can imagine that having the pressure of the breast feeding issue on top of that wasn't great.
With my second son I thought I was all prepared. I had all the techniques to help with latching on and I had lots of acidophilus etc to stop the thrush setting in. Alas we had the same problems and I very quickly decided that I couldn't put myself, and my son, through all that again. It was the best decision I could have made and I felt so relieved once I'd made it! I expressed for four weeks and then went exclusively on to formula.
I was envious of my friends who seemed to find it so easy (and felt rotten opening my carton of formula as they popped their babies on on their breasts) but it turns out that many of them had other issues that I didn't have. We're force fed this perfect image of motherhood that is so detrimental to all of us struggling with the reality. I have to admit that while I still agree with the benefits of breast feeding, I find it soooo tiresome the way proponents imply that it's the panacea to all ills (I'm sure someone, somewhere, has linked it to world peace!!
) and that formula is the devil's elixir!! A friend of mine breast fed for a year and her child is so allergic to things that she can't even be in the same room as a prawn! Incidentally my son's eczema sorted itself out despite not being exclusively breasted. Both my boys are in good health and their immune systems appear no different from their friends who were exclusively breast fed.
Things are what they are sometimes and all we can do is our best. It sounds as if you want the best for your child and that is absolutely the most important starting point for raising a healthy and happy child. It is hard when we can't do everything that we want for our children but I can assure you that the passage of time will ease your sadness and you will be able to see the many good things that have worked out well.
