I know how you feel. My guy was 2 weeks early, 8lbs, 6oz, and breech, so I had a c-section. My first was a natural birth, so having the c-section wasn't something I really wanted to do and I blamed myself for his issues because I had made the decision to do so. Even though I breastfed for 5 months, each time was torture. I would bite on a burping cloth every time he would latch on, and after a minute, I was able to tolerate it without the cloth.
I feel that women are done an injustice when it comes to breastfeeding. I know that it's better than formula, but it's also not as easy as it is made out to be. I would say that 90% of of the new mom's I know struggled with breastfeeding but when you're pregnant, all of the information is how natural it is, and how it's instinct for your baby; which leads a new mom to think that something is wrong with her if it doesn't go smoothly. I too was determined with my first child and ended up pumping for 7 months. I went to countless breastfeeding clinics and no one could help us, she just would not nurse.
When I realized that I was not the only one, it made me feel better and I was able to allow myself not to feel guilty for something I had no control over. I really tried, but for reasons beyond me, it didn't work. My kids are healthy and happy, so that's what my focus should be.
As mom's we need to cut ourselves a break every once in a while and realize that we have done a lot up to this point. We carried these sweet blessing for 9-10 months, went through the pain of labour, and even nourished them from our bodies. Now we just continue to help them as they grow. They don't come with a manual, so it's a learning game for us all. Each day I spend with my children is a new and beautiful experience. As they get older, I see new personalities developing and it gets easier when they start "giving back" attention-wise.
As for the food issues, hang in there. I too was terrified to try certain things, but it has been okay. I think it was just his body needing to develop more and now that it has, his digestive system can tolerate more.
